Plug-On PI Controllers

This new line of plug-on PI controllers is for Solenoid Continuous Control of level, flow, temperature, or pressure in liquids and gases. The controllers, Type 8623-2, 8624-2 and 8625-2, are easily mounted to the manufacturer's Type 6022, 6023 or 6223 ¼-in. – 1-in. solenoid valves or any DIN 43 650A-compatible proportional solenoid valve and provide "ready-to-use", programmable control.

These units also directly accept industry standard signals from process sensors (flow, level, pressure or temperature) to provide complete control loop solutions. The compact electronic PI controllers are integrated in a polyamide NEMA 4 housing for direct connection to continuous solenoid control valves. The controller consists of a microprocessor-based, self-supporting and programmable unit that mounts directly on the solenoid valve. The unit has an easy-to-read LED analog display and three push buttons for:

•Setting the control parameters
•Configuring the set point
•Monitoring the control valve
•Setting the K factor (flow only)
•Non-inverted/inverted control unit direction
•Heating and cooling (temperature only)
•Elimination of turn-down ratio

The series has three versatile models: the Type 8623-2 Flow Controller with two frequency inputs for flow sensors, Type 8624-2 Pressure and Level Controller using a standard 4-20mA input signal, and Type 8625-2 Temperature Controller with an RTD (PT 100) sensor input.
