The PCH Relay Box is an optional module in the PCH Link Concept series. Its 12 relay outputs indicate various vibration and process alarms from the PCH 1420 vibration monitor.
The PCH Relay Box is connected to the PCH 1420 Vibration Monitor via a DIN rail bus.
The PCH 1420 and PCH Relay Box are paired and configured with the PCH Vibration Studio software. A maximum of one PCH 1420 monitor can be connected to the R2C bus at a time.
The PCH 1420 vibration monitor comes with different firm ware. Please note the firmware of your PCH 1420 monitor when ordering the PCH Relay Box version 1 or version 2:
- Version 1, CHB 1123 / CHF 8400: Up to v.20.30

The vibration monitor is prepared for DIN rail installation with an IP20 DIN rail enclosure with screw terminals.
Alarm and test functionality
The relays are galvanically isolated and can be activated for test purposes either using the PCH Vibration Studio software or by a Digital Input on the PCH 1420 Vibration Monitor.
In the events of alarms, power outages or system failures, the relays will break the signal chain.
