Temperature Relays TR660IP monitor up to 6 sensors for up to 7 limits. Different sensors can be connected at the same time, e.g. Pt 100 (RTD) and PTC thermistors. Typical applications are monitoring of motors, generators or transformers. An other application is the use as a two or more step controller with additional monitoring of over- or undertemperature or monitoring of differences in temperatures of 2 sensors.Preset programs allow easy setting e.g. monitoring of transformers with/without monitoring of temperature of core or with/without controlling a ventilator.If the evaluation "2 out of x" is activated with several connected sensors, an alarm is only triggered when the limit value is exceeded in 2 sensors. This prevents false alarms due to a fault in one sensor.

The TR 122 DA transduces the measured temperature/resistance to a proportional DC-current. Applications of the TR 122 D(A) are:Monitoring of temperatures with pre-alarm and alarm in machines and plantsControlling of temperatures e.g. for heated sample gas lines or refrigerating plantsTransducer for Pt 100 (RTD) and resistance (TR 122 DA only)Overview of Functions1 input sensor, Pt 100 (RTD) or resistanceMeasuring ranges -199...850°C / 0...850 Resolution 0,1 °C / within the ranges -19,9...99,9 °C / 0-99,9 2 relay outputs (each 1 change-over contact)1 analog output 0/4-20 mA scaleable (TR 122 DA only, not potentially separated from the inputs)Universal power supply AC/DC 24-240 VStorage and display of the measured MIN- and MAX-values 

The Safety Temperature Limiter type STR 100 is an electronic thermostat monitoring the temperature of heating equipment and machinery. When the permitted temperature-limit is exceeded or in case of a malfunction, the STR 100 switches off without delay. An active reset must be made for a restart. The temperature limit is adjustable with a scaled potentiometer. An unintended or unauthorized adjusting of the limit is prevented through a lead-sealed transparent cover.With supply voltage switched on, the STR 100 operates in a changeable lockout mode and the relay must be started by a reset (manually with built-in reset button or external reset) to make contact (no) close. Applicable for plants with supervised operation. The mode of operation corresponds to type 2BJK according EN 60730/VDE 0631.The temperature is measured with a Pt 100 resistance temperature detector (RTD) according to EN 60751 / IEC 751. The process qualification in combination with the sensor must be proved. To fulfil affords for higher safety functionality the function has to be routine-tested periodically. The thermostat series STR 100 meets safety category 3 (Safety of machines EN 954-1, TÜV Rheinland documents T 24/00 + T103 2007 Z1 + T103 2007 E2). If safety approval is recommended only use listed RTD.Temperature LimiterA temperature-limiter is an equipment that switches of permanently (locked) after the limit has been exceeded. A reset (manually or with a tool) is possible after the temperature has fallen below switch-back point (limit minus hysteresis).Safety Temperature LimiterA safety temperature limiter is a limiter that fulfils in addition the requirements of extended safety according to DIN 3440. 

Temperature relay to protect transformers against excess temperature and to control a fan.The temperatures in the windings are monitored with three Pt 100 sensors. The core temperature can be monitored with a fourth sensor.The 4 alarms/output relays are used to control the fan, to signal an advance warning and to switch-off the transformer. Various programs facilitate using the alarm ideally for each application. Depending on the program, e.g. an extra relay is available for the fault message or for triggering due to exceeding the maximum core temperature.Other usesAlternatively, with the fourth sensor the temperature of the room the transformer is located in can be monitored and, with the alarm, the room ventilation can be controlled. The device can also be used for other tasks for temperature monitoringe.g., for motors.Overview of the functions4 Sensor inputs Pt 100 (RTD), 2 or 3-wire connectionLarge monitoring range -199…+850°C / -199...+999°F4 Alarms / Relays3-digit digital display (resolution 1°C / 1°F)4 LEDs sensor4 LEDs relay4 LEDs alarm1 LED errorControl voltage AC/DC 24-240 VClear displays and simple programmingMin and max sensor values can be savedCode lock against unintended / unauthorised changes to the settingsOptional RS 485 interface with Modbus RTU protocolEasySimulation for simple sensor value simulation 

The Pt 100 thermostat TR600 is a temperature controller and monitors up to six Pt 100 sensors at the same time. Six switching points and six relays permit almost any combination of switching action. It also can select the highest temperature of a group of three or six sensors. The temperatures of two sensors or groups of sensors can be issued to 2 analog outputs i.e. for remote displays or further evaluation. Programming is very variable and simple.Due to the fact that 6 type Pt 100 sensors can be connected, the unit is especially suitable for temperature monitoring wherever up to 6 different measuring points must be monitored simultaneously:motors and generators with simultaneous monitoring of bearings and coolant.transformers with additional monitoring of the core temperature also.power machines and plantsApprovalUL E377414 Process Control Equipment, Electrical - ComponentOverview of functionsMeasuring and monitoring range -199 ... +800 °C6 sensor inputs with 2- or 3-wire connection7 relay outputs with change-over contactAlarm 1 … 6 relay K1 (11/12/14) ...

The PTC-resistor trip device MSF220SE monitors the winding temperature of machines and equipment. Signals, that can be used as ”early warning" or ”malfunction" (switching-off), are transmitted as soon as the admissible limit temperature is exceeded.Two PTC-circuits can be connected to this unit. The integrated rise-delay time ensures a reliable mains voltage build-up.Function2 PTC resistor circuits, 1 to 6 PTC each (max. cold resistance of circuit 1500O each)potential-free contact for alarm 1potential-free contact for alarm 2voltage of pin 3 is connectet to pin 1 with a time delay of 2 sec., replacing an additional timing relay.alarm 3 for check of relay K3LED´s signal state of relays K1 and K2relay K3 picks up time-delayedTEST-button for ALARM 1 and ALARM 2NoteThanks to the delayed switching-on of the error message (approx. 2 s) after the switching-on, this device is especially suitable where an auxiliary voltage is not available and the secondary voltage of the monitored transformer is being used. The MSF220SE can furthermore be used advantageously when combining it with operating current releases. For additional devices, the control voltage is available at terminal 1 time-delayed. In case of a breakdown of the supply voltage, the control voltage is available at terminal 7 and can be used as a message. (Attention! This message will also be given for approx. 2 s. after switching-on.)Functional descriptionPTC-circuits in closed-circuit current principle. When the closed-circuit current flows, both output relays K1, K2 are picked up. Approx. 2 sec. after switching on supply power, relay K3 picks up time-delayed, closing the contact circuits at terminals 31, 14 and 31, 24. As soon as the temperature of the early warning has been reached, relay K1 releases (terminal 31, 12 closed), the alarm 1 is given. If the temperature of malfunction is reached, also relay K2 releases (terminal 31, 22 closed). This alarm 2 can be used to switch off the equipment. If the temperature drops to approx. 5 °C below the temperature of malfunction or early warning, the relays K1 and K2 resp. are switched on again.TEST: LED "ON" – flash -> +2 s -> Alarm 1 -> +3 s -> Alarm 2 

The MSF 220 V is particularly suitable for the temperature monitoring at dry transformers. 3 PTC-circuits with different nominal response temperatures (NRT) can be connected to this unit, one for controlling a fan (forced cooling) and two for alarms. Each PTC-circuit is monitored for break and short circuit. This reduces the probability of false alarms.3 PTC-circuitsMSF 220 VU for universal supply voltage AC/DC 24-240 Vintelligent control of fan (relay K0, 1 normally-open contact)ALARM 1 in closed-circuit current mode (relay K1, 1 change-over contact) for pre alarm. Signals also error in any sensor and interruption of supply voltage. ALARM 2 in operation current mode (relay K2, 1 changeover contact).
