R1-120TC and R2120TC are 2 multiloop thermal controllers able to operate on 6 loops . All types of thermocouple inputs can be connected directly to the instrument , without external cold junction compensation. The R1-120TC has common ground negative thermocouple inputs wheres R2 model has isolated input channels. Two digital outputs for each channel are available allowing warm / cold thermal processing for accurate themperature controlling. No recalibrating procedures are required during service . Themperatures reading are accurate and reliable. These modules are particularly employed in hot runners plastic injection molders.
