System compatibility16201-1-7 is compatible with SIEMENS MOORE APACS+ and QUADLOG distributed control system. It pairs with SDM / CDM digital I/O modules for relay signal marshalling and field wiring interface.

FunctionThis relay marshalling termination assembly serves as intermediate relay signal conversion and wiring terminal unit. It receives digital control signals from DCS I/O module, drives built-in relay contacts to switch field equipment, and provides centralized terminal blocks for convenient field cable connection, isolation between DCS backplane and field loads.

InstallationCut off power before installation. Secure the assembly inside control cabinet. Connect ribbon cable between this termination assembly and corresponding SDM/CDM I/O module. Wire field load cables to relay terminal blocks, check contact continuity after wiring.

InterfaceFlat ribbon cable connector, relay contact terminal blocks, channel status LED indicators.

FeatureBuilt-in relay contact isolation, centralized marshalling wiring, channel status LED indication, surge protection, easy field wiring and troubleshooting. Obsolete legacy spare part, used for APACS+ DCS discrete control loop maintenance and replacement.

DiagnosticNo relay action: check 24V DC power supply, ribbon cable connection and DCS output command. Relay contact failure: inspect contact load rating and wiring short circuit. LED no light: verify module backplane communication and channel configuration.

Product BriefSIEMENS MOORE 16201-1-7 is APACS+ SDM relay marshalling termination assembly, widely used in petrochemical, power and pulp & paper industries for on-off control of solenoid valves, contactors and alarm devices.
