DESCRIPTION

The PCU Controller accepts either 0 to 10 VDC or a 0 to 20 mA DC input

signal, precisely scales the process signal according to programmable scaling

points, and provides an accurate output control signal (time proportional, linear,

or valve position) to maintain a process at the desired control point. A

comprehensive set of easy to use program instructions allows the controller to

solve various applications.

The controller can operate in the PID control mode for both the main output

and optional secondary output, with on-demand auto-tune, that establishes the

tuning constants. The PID tuning constants may be fine-tuned by the operator

at any time and then locked-out from further modification. The controller

employs a unique overshoot suppression feature, which allows the quickest

response without excessive overshoot. The unit can be transferred to operate in

the manual mode, providing the operator with direct control of the output. The

controller may also be programmed to operate in the ON/OFF control mode

with adjustable hysteresis.

Dual 4-digit displays allow viewing of the process value and setpoint

simultaneously. Front panel indicators inform the operator of the controller and

output status. Replaceable and interchangeable output modules (Relay, Logic/

SSR Drive, or Triac) can be installed for the main control output, alarm

output(s) and secondary output.
