Series 1ZC can be used for setpoint control of a single control loop and has two independent outputs configurable as direct-acting, reverse-acting or alarm. Designed for use in nonindicating subpanel applications, the autotuning PID controller will communicate with a control computer or programmable logic controller via a built-in bidirectional RS485 serial communications interface. The controller from Athena Controls Inc. supports a range of sensor inputs, including thermocouples, linear inputs and two- or three-wire RTDs.
