CHQ-PCM(SCI),Input and Output Control Module
CHQ-PCM (SCI) is a loop powered input/output module with four independently variable relay outputs and four supervised inputs Outputs with N-free contacts /O and N/C volts and can be controlled separately under the control of a fire alarm panel, used to control devices such as dampers or to shut down machines and equipment
Four inputs are provided level for local and fire fault monitoring and they are fully supervised for open circuit and short circuit which, if necessary, can be switched on or off in pairs using a bidirectional DIL switch. Note: - The state of the relay contacts will not be determined until the device is powered up. The unit is also available in a DIN Rail enclosure (CHQ-PCM/DIN (SCI)). A rear box is also available (CHQ-BACKBOX), which, when used in conjunction with CHQ-PCM (SCI), increases the IP rating to IP. When using heavy cables, we recommend using the SMB-1 Module enclosure with the SMB-ADAPTER plate.
