SR336 alarm unit – Inor

The SR336 is an alarm unit with programmable alarm functions, designed for temperature monitoring with RTD sensors in a 2-wire sensor connection in the process industry.

Two output relays with synchronous switching are available with functions such as MIN/MAX alarm in open or closed circuit. LEDs on the front panel indicate the alarm status and correct power supply.
