CHQ-PCM(SCI) is a loop-powered input/output module with 4 independent relay outputs and 4 supervised inputs.

Outputs are provided with voltage-free N/O and N/C contacts and can be driven separately under panel control, to be used for control of devices such as gates, or shutdown of plant and equipment.

The 4 inputs allow local fire and fault monitoring, monitoring open circuit and short circuit, and if required, can be enabled or disabled in pairs using a two-way DIL switch.

When using heavy cables, we recommend the use of the SMB-1 modular housing in conjunction with SMB-ADAPTOR, a back box (CHQ-BACKBOX) is available which, when used in conjunction with the CHQ-PCM(SCI), increases the IP rating to IP65.

Also available in DIN-mountable housing: CHQ-PCM/DIN(SCI)

Note: The status of the relay contacts will be indeterminate until the unit is turned on.
