Item description

Short description:

WAGO's Thermocouple Threshold Value Switch for TC sensors monitors and reports signals of up to two switching thresholds.

Features:

Both digital signal output and relay with changeover contact react to configured measuring range limits (switching ON/OFF delay and threshold value switch function configurable with up to two threshold values).

Adjustable software filter

Input/Output response simulation via configuration display

Safe 3-way isolation with 4 kV test voltage per EN 61140

Note:

Additional setting options via interface configuration software or interface configuration app
