General Description
The TCY3 is a stand-alone electronic universal controller with two autonomous control loops. Each control loop may use up
to 2 PID sequences and 6 binary sequences. The TCY3-T0121R features 1 NTC temperature sensor and 1 analog input, 2
binary outputs and one analog output. The outputs need to be assigned to the control sequences by parameters. A
detailed configuration is possible by following a simple setup routine. The TCY3 can be configured using the standard
operation terminal. No special tool or software is required.
