MultiTek Thermocouple Trip Relay
| SELECTION GUIDE M200-TJU J type thermocouple under trip M200-TJO J type thermocouple over trip M200-TKU K type thermocouple under trip M200-TKO K type thermocouple over trip TYPICAL APPLICATIONS Designed to monitor thermocouples and provide a relay signal if the temperature being monitored exceeds the pre- set limit. J and K type thermocouples inputs are available covering a wide range of temperatures. As is common with all the M200 relays, on over units the relay energises when the input signal exceeds the trip point and on under units the relay de-energises when the input signal goes below the trip point. A red LED indicates the state of the relay, whilst a green LED indicates the condition of the power supply.
