Outputs 50
Relays and Analog Outputs can be used as part of a process control system.
Relay contacts are connected to control elements e.g. valves, pumps, motors used for process value regulation.
They are also used to interface with automated probe cleaning devices.
Analog Output signals are interfaced with supervisory control and automation systems or to a simple chart
recorder to capture process measurements.
Note: Controller model determines the number of relays and analogs.
