Article number: T224353

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) or analogue outputs 0/2-10 V or 0/4-20 mA.

Accessory: Installation frame ER8 for panel mount
