Designed to communicate with a control computer or PLC, the DIN-rail-mounted, autotuning PID controller fromAthena Controls Inc.can be used for precise setpoint control of a single control loop. Series 1ZC supports a range of sensor inputs including thermocouples, linear outputs, and two- or three-wire RTDs, and it has electromechanical or solid-state relay, 4 to 20 mA and pulsed 20 VDC outputs. Inputs and outputs are isolated optically to minimize noise.
