CHQ-PCM(SCI) SIL, SIL2 Standard Input Output Control Module
CHQ-PCM (SCI) / SIL is a loop powered input / output module with four independently variable relay outputs and four supervised inputs The outputs have zero contacts has N/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 for local fire and fault monitoring and they are fully monitored for open and short circuits 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 on.
