Industrial Process Controllers. Each practical work study system consists of a bench top process demonstration unit and a control console, that contains the power supplies and interfacing for all measurement and actuation signals. Specific industrial controllers are available as accessories to further develop the practical instruction courses possible.
The PCT19BR Programmable Logic Controller (PLC) enables multi-channel compatibility with selected equipment from the Armfield range. Accepts six analogue and eight digital input signals, and provides two analogue and eight digital outputs for use in a wide variety of control loops.
The PCT20H PID controller connects to selected Armfield equipment, providing an analogue input/output, relay and alarm sockets for a digital output control action. An RS232 port enables serial communications with a user-provided PC.
The PCT23MkII demonstrates a complete range of process control methods and strategies, including manual control, single feedback loops, cascade loops and distributed supervisory control of the process by a remote PC.
The system is a miniature replication of a true production process. The student is presented with real process control problems, with realistic dynamic behaviour and instabilities.
