TC1818a
Control and Monitoring Module
The TC 1818a is a multicircuit microprocessor-based temperature
control and monitoring module developed specifically
for heat tracing. The unit provides control and
monitoring capabilities via digital information display for a
maximum of 18 heat tracing circuits. The module can be
configured for either process sensing control (with an RTD
for each circuit) or ambient sensing control (with a user’s
choice of one or two RTD inputs).
As a modular unit, the TC 1818a is typically located
within an enclosure suitable for the application. For
maximum versatility, multiple modules can be installed
in a common enclosure. Individual six-point
sensor modules handle input to and output from
the TC 1818a via ribbon cable connectors. Up to
three input and three output modules can be connected
to each TC 1818a.
Module supply voltages 110-120 or 208-240 Vac
