Revision 2
DESCRIPTION & TECHNICAL DATA
DESCRIPTION
The electronic temperature controller Ex-TC/…-It is part of an eltherm family of microcontroller-supported electronic temper-
ature controllers and limiters. It is designed for operation with electrical trace heating systems and can be used to maintain
temperatures and for frost-protection applications in areas subject to explosion hazard. The control keys and sensor connections
are designed to be intrinsically safe.
All models have a sturdy plastic housing to IP 65 and a mounting base flanged onto the housing that is optimally suited for
mounting pipelines. Depending on the intended purpose, the Ex-TC/... is available as a temperature controller with alarm relay,
temperature controller including RS 485 interface with Modbus protocol or a controller/limiter combination with alarm relay.
The Ex-TC/...-It is able to switch high nominal currents and with its round shape it ensures optimum mechanical safety. The cover
closes quickly with a snap lock, making it easy to handle where it is used. All variants are suitable for use with our self-regulating
heating cables (ELSR) and resistance heating cables (ELK, ELP).
