TC03 1/16 DIN Temperature Controller


The TC03 is a 1/16 DIN microprocessor-based single channel, temperature controller that is capable of monitoring and controlling temperature in applications such as environmental chambers, furnaces, ovens etc. The small, lightweight, controller fits in a small panel (1.78" x 1.78" opening) and features a simple to use 3 button, 2x16 LCD, back lit interface and has remote control capability using either RS232 or RS422.

The controller accepts K,J, T thermocouple or an RTD sensor as input and uses a PID algorithm with pulse width modulated TTL compatible outputs for driving heat,cool and circulation fan relays. Installation of the TC03 controller into a system is easily accomplished via the I/O board that will accept 110/220VAC power input for the TC03 controller and provide interfacing to SSR's via the 8 position terminal strip. In additon to a heat,cool and fan output, the controller also has a compressor output, auxiliary output, digital input as well as a failsafe input (typically from a safety sensor such as a bi-metal thermostat) that disables all outputs if asserted.

In addition to accepting a single segment (set point, ramp rate and soak time), the TC03 controller will accept up to 10 set points (SCAN temps), 10 ramp rates (SCAN ramps) and 10 soak times (SCAN times) and execute these up to 1800 cycles or indefinitely.

These set points can be entered either locally from the 3 button user interface or remotely via RS232 or RS422.
Upon completion , the temperature controller gives an audio and visual indication as well as an interrupt character remotely when time-at-temperature expires.
