Universal Relay Box Type URB40

Relay extension box type URB40, for universal relay box type UR
The 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

 

Applications

With 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 alarms
  • Easy extension of existing control systems of the UR series
  • Space-saving installation
Approval: EU / UKCA-Declaration of Conformity
Extras: UR-Series
Outputs: Outputs/Relays, > 2 outputs, Interface/Bus
Product group: Temperature Measurement, New Products
Supply voltage: AC/DC 24 - 270 V

Universal Relay Type UR840IP

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.Accessory: Installation frame ER8 for panel mount ApplicationsThe UR840IP is used where one or more of the following features a required:The UR840IP is used to advantage wherever the following features are requiredmonitor up to 8 different analogue measured values and transfer them to the InternetMeasured value query and remote maintenance via intranet/internet Discover the difference between our UR series!
