System compatibility16201-1/9 belongs to Siemens Moore APACS+ and QUADLOG series. It works with QUADLOG safety discrete output modules and APACS+ SDM discrete modules, used as relay marshalling termination assembly to isolate and drive field ESD solenoids, safety relays and field actuators.

FunctionThis SDM/CDM relay termination assembly provides relay isolation and field signal terminal interface for QUADLOG SIS and APACS+ DCS discrete output channels. It receives control signal from rack I/O module, triggers built-in safety relay contacts to switch field power circuit. It adopts de-energize-to-trip safety design for emergency shutdown loop, provides electrical isolation between control side and field side, integrates screw terminals for field wiring connection.

InstallationPower off the cabinet power and field circuit before installation. Snap the assembly onto DIN rail. Connect ribbon cable between termination assembly and I/O module rack. Wire 24VDC control power and field actuator cables to terminal block. Verify relay action and wiring continuity, complete safety loop test before online operation.

InterfaceRibbon cable connector to I/O rack, multi-channel screw terminal block, built-in relay units, status LED indicators.

FeatureQUADLOG / APACS+ dedicated relay marshalling termination assembly, safety de-energize-to-trip relay design, Class I Div.2 hazardous area approval, high contact capacity, galvanic isolation between system side and field side. Obsolete legacy spare part, used for QUADLOG SIS and APACS+ DCS safety discrete output loop maintenance and replacement.

DiagnosticRelay no switching action: check 24VDC control power, ribbon cable connection and module output command. Contact cannot load field device: inspect relay contact burnout, field short circuit and wiring loose. Abnormal loop alarm: check wire breakage, terminal looseness and field actuator coil integrity.

Product BriefSiemens 16201-1/9 is SDM/CDM relay marshalled termination assembly for APACS+ DCS and QUADLOG SIS, widely used in petrochemical, power and pulp & paper industries for safety ESD solenoid driving and discrete signal isolation.
