The PRETECH Solenoid Coil Module monitors the coil and associated wiring continuously. While the coil is normally de-energized, a small monitoring signal passes through the coil to monitor for variations. By this means, the solenoid and field wiring are monitored for open-circuits and short-circuits which would otherwise prevent proper operation. If a command is received to operate the coil, the internal double pole relay changes state to supply the full operating voltage to the coil. This control source is compatible directly with most programmable logic controllers and can either be DC voltage or a dry contact.
This module offers the additional feature of monitoring the availability of the main power source necessary for energizing the solenoid. Should power become unavailable at any time, a fault will alert the necessary system or operator that the solenoid cannot be energized if commanded.
The LED display is color coded for easy troubleshooting of faults and conditions.
Our modules can monitor almost any solenoid! Our engineers will review all data and ensure the solenoid coil is properly protected!
