CHQ-SOM has been designed to allow the connection of 1 relay output to the ESP loop.


Incorporates 1 voltage-free relay contact that can be used as N/O or N/C, the contact has a rated capacity of 30 VDC (maximum), 1 A (resistive load).


It has 3 color-coded connection wires, as well as a wiring terminal block for loop connection.


To maintain LPCB approval, the device must be mounted in an SMB-1 housing (or an equivalent housing made of polycarbonate or similar material that is impact resistant according to EN54-18:2005 Clause 5.9) together with SMB-ADAPTOR, using two screws or two nuts M3.


NOTE: The status of the relay contacts will be indeterminate until the unit is powered on, if the PCB is removed from the protective outer casing, the EN54 certification is cancelled.
