Red Lion Controls

The Process Control Unit (PCU) is a multi-purpose series of industrial control products that are field-programmable for solving various applications.

This series of products is built around the concept that the end user has the capability to program different personalities and functions into the unit in order to adapt to different indication and control requirements.

PCU Process Control Unit

Instruction Guide

The PCU Controller accepts either a 0 to 10 VDC or a 4 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 positioning) to maintain a process at the desired control point. Acomprehensive set of easy to use steps allows the controller to solve various application requirements.

The controller can operate in the PID control mode for both the main output and optional secondary output. On-demand auto-tune establishes the tuning constants. The PID tuning constants may be fine-tuned by the operator at any time and locked out from further modification. The controller employs a unique overshoot suppression feature that 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 can also be programmed to operate in the ON/OFF control mode with adjustable hysteresis.

If you are looking for Red Lion PCU PID Controllers, please call us at (844) 331-9379 or email us at we will do our best to help you find the PCU01000 PID controller that you are looking for at the most competitive prices possible. If you are searching for PCU01001 PID controller technical information (data-sheets) please use the datasheets or product selection guide page links.

Dual 4-digit displays allow viewing of the measured value and setpoint simultaneously. Front panel indicators inform the operator of the controller and output status. Replaceable and interchangeable output modules (Relay, SSR Drive, or Triac) can be installed for the main control output, Alarm output(s), Secondary output, and Valve Positioner outputs.

Optional dual alarms can be configured to activate according to a variety of actions (Absolute HI or LO, Deviation HI or LO, Band IN or OUT, and Valve Fail Detect) with adjustable hysteresis. A standby feature suppresses the output during power-up until the process stabilizes outside the alarm region. An optional secondary output is available (for processes requiring cooling, pH balance, etc.) that provides increased control accuracy and response.

A linear 4 to 20 mA or 0 to 10 VDC output signal is available to interface with actuators, chart recorders, indicators, or other controllers. The type of Linear DC output is determined by the model ordered. (See Ordering Information, page 84, for available models.) The output signal can be digitally scaled and selected to transmit one of the following: % output power, measurement value deviation or setpoint value. For Linear DC control applications, the adjustable output demand dampening, output deadband, and output update time parameters expand the versatility of the PCU to final control devices.

The optional Motorized Valve Positioner directly controls the position of a valve by the use of twin outputs (open and close) to control the direction of motor rotation. The motor position defines the opening position at the valve. Two control modes are possible: position control, which makes use of the slidewire feedback signal supplied with the positioner and velocity control, in which no slidewire feedback signal is used. Parameters are provided to adjust the operation of the valve.

Weidmuller Displays

The LPD450F display allows you to display process variables. The display is loop powered by the 4-20 mA current loop with no external supply required. The twenty-mm LCD displays can be read even under poor light conditions. A sheet of perforated self-adhesive labels is included. They include standard engineering units and can be used for all label needs. The electronic subassembly is housed in a rugged, glass reinforced

SymCom Modules

The CIO-PR Module is a convenient, cost effective Profibus interface device capable of providing discrete control and monitoring of motor starters, drives and other devices over a Profibus network. The CIO-PR module provides four solid state 24VDC inputs and two AC/DC rated relay outputs. It can function as a stand-alone I/O device or can be connected to any model 777-P series unit to relay real-time information
