CHQ-SOM
The CHQ-SOM has been designed to allow a single relay output to be connected to the ESP loop.
The unit incorporates a volt-free relay contact that can be configured as either N/O or N/C, the relay contact is rated to 30 V dc (max), 1 A (resistive load). The CHQ-SOM features three colourcoded flying leads, the unit also features a wiring terminal block for loop connection.

NOTE: The state of the relay contacts will be indeterminate until the unit is powered.
To maintain LPCB approval the device must be mounted in an SMB-1 enclosure (or an equivalent enclosure made from polycarbonate or a similar material which is impact resistant as per EN54-18:2005 Clause 5.9) in conjunction with the SMB-ADAPTOR plate, using two M3 screws or two M3 nuts and bolts.
NOTE: If the PCB is removed from the protective outer casing the EN54 approval is voided.
