TC201a
Control and Monitoring Module
The TC 201a is a microprocessor-based temperature
control and monitoring module developed specifically for
heat tracing. The unit provides control and monitoring
capabilities via digital information display for one heat
tracing circuit with input from two RTDs. Each RTD can
provide independent sensing of the heated surface and, as
a safety feature, can activate a high temperature alarm and
shut down the heater.
As a modular unit, the TC 201a is typically located within an
enclosure suitable for the application and can be configured
to control a solid-state or mechanical relay. Multiple
modules can be installed in a common enclosure.
Module supply voltages 110-120 or 208-240 Vac
