1. INTRODUCTION
1.1.
Application
The multi-channel indicator/controller TC800 is used for indicating, monitoring, and controlling various
technological variables. With its compact size and up-to-eight inputs, the device may be successfully used
as a multi-channel limit monitor. TC800 may also serve as a two-, three-, and multi-stage ON/OFF controller, and,
thanks to its limit output relays, it may be also be used to control motorized valves.
1.2.
Main features
Thermoresistive (RTD), thermocouple, and standard current and voltage signal inputs;
Discrete input for external channel selection;
Various programmable modes of operation;
A rich set of parameters for controller programming;
Protection against unauthorized access;
Software compensation of RTD sensor line resistance;
Cold-junction temperature compensation;
Sensor and sensor-line break monitoring;
Full self-testing;
Saving all parameters in nonvolatile memory; restoring at power-on;
Communication with PC via digital interface; connection of several devices into one network.
