General Specifications Model UT, UT Temperature Controller GS CE-E GENERAL UT series temperature controllers provide only the functions and size you require for your application.

1 General Specifications Model UT, UT Temperature Controller GS CE-E GENERAL UT series temperature controllers provide only the functions and size you require for your application. /6 DIN sizes is available. Easy-to-read displays show input and the setpoint. T/C or RTD inputs are standard and the output type is selectable: ON/OFF, voltage pulse or DC current. The controllers operate in an Automatic mode only. Optional alarm contact outputs, retransmission output, contact input setpoint selection and RS8 communication are available. Each features dynamic self-tunig function for easy start up. Super Control fuzzy logic for overshoot suppression is a proven champion. MODEL AND SUFFIX CODES Model Suffix code Description UT...
