Keyswitch On-Off-Auto Relay Module Cat. #: 330371

This relay module can be controlled by a PLC/DCS digital output or manually. Configuration is via keyswitches so accidental or unauthorized operation can be prevented. The first keyswitch is used to enable or disable the module. When switched to the “DISABLE” position the relay cannot be energized so the normally closed contact is closed. The status LED’s – “ON” and “AUTO” – are both off. Once switched to the “ENABLE” position the “AUTO – MANUAL” keyswitch can now be used. In the “AUTO” position the relay is controlled by a 24Vdc signal applied to the “PLC” terminal. The “AUTO” LED is on while the “ON” LED illuminates and the STATUS output is activated when the 24Vdc signal is applied. Switching to “MANUAL” allows the relay to be controlled from two on-board pushbuttons. Once the module is in the desired configuration the keys can be removed to prevent tampering. The same key works in both keyswitches.
