Do you have a question?
Web-IO universal limit value relay with Ethernet interface, built-in web server and 8 inputs for temperature sensors or other analog signals. The UR840IP can be connected to the internet or an intranet and operated via TCP/IP from a normal PC with a suitable browser.
The device can simultaneously evaluate and monitor up to 8 different input signals. Each of the 4 output relays can be assigned up to 8 limit values, one per input. If a limit value is reached, an alarm is triggered and a relay switches. Example: Alarm 1 is activated when a temperature is exceeded at sensor input 3 (e.g. Pt 100) or the signal from a pressure transmitter (e.g. 4-20 mA) at input 5 falls below a limit value. The device also has an RS485 interface (Modbus RTU) that can be used to connect current sensors type STWA4MH and the relay box type URB40.
NEW: Data visualization in the web interface.
Expandable by 4 additional relay outputs with the URB40!
ZIEHL devices neatly integrated into control panels and control cabinet doors with our installation frames type ER!

Accessories
You found a device in that meets your requirements and you want to install it in a control panel or in the door of a control cabinet?With the installation frame of the ER series, this is possible for all ZIEHL devices in housings V4, V6 and V8 (width 70/105/140 mm).Enclosed by a high-quality frame made of anodized aluminum, all displays can be read outside the control cabinet. Switches, buttons and joystick can be operated.
Relay extension box type URB40, for universal relay box type URThe URB40 universal relay box is an extension box for UR devices that can be used to control up to four additional relay outputs via Modbus RTU. The URB40 monitors the communication between the devices and can transfer each relay output to a predefined state in the event of a timeout. The device has no operating elements and is controlled and configured exclusively via the RS-485 interface.Accessory: Installation frame ER4 for panel mount ApplicationsWith the URB40, an additional four alarms and relays are available, and the device can also be easily operated on other control systems via the integrated RS 485 interface.4 additional alarmsEasy extension of existing control systems of the UR seriesSpace-saving installation
STWA4MH is a measuring transducer. It measures AC up to 60A and has an RS485 interface (Modbus RTU). The measured analog current value is made available as a digital signal and can be read by a PLC, an IPC or a master computer.The conductor to be measured is passed through an opening (Ø 11 mm). In case of small currents, the sensitivity of the current transducer can be increased by looping through the current-carrying conductor several times, e.g. double looping doubles the sensitivity. The measuring range of the STWA4MH is reduced by multiple looping. To measure currents of any size, the STWA4MH is simply looped into the secondary circuit of a large current transformer with a secondary output of 5A (lead the cable through STWA4MH several times).Application:The STWA4MH enables the space-saving an cost-effective measurement of the actual value of an alternating current. Compared to transducers with analog output, the bus technology significantly reduces the effort for the hardware (inputs) and the wiring. Applications are e.g. the recording of the current consumption of electrical motors in processing machines. Here the feed can be regulated depending on the load on the motor. Another example is the monitoring of consumers, e.g. heating elements, for failure.
