T412 Temperature Controller

The T412 temperature controller is a single input temperature controller that provides plenty of features for monitoring a single hot spot.  The input can interface with a RTD Pt100 sensor as standard but has the option for using a Tck thermocouple depending on your sensor preference.  The input is protected from electromagnetic interference for consistent, reliable performance.  The outputs consist of 3 relays; 2 alarm relays for different trip thresholds and another fault relay for signaling a sensor fault or a self diagnostic fault on the PC board.

On request a protective coating can be applied to the electronics board for tropical climates.
