System compatibility16191-21 belongs to Siemens Moore APACS+ and QUADLOG series. It is matched with EAM Enhanced Analog Module, serves as analog signal marshalling terminal assembly, compatible with APACS+ DCS and QUADLOG SIS analog I/O modules.

FunctionThis EAM marshalled termination assembly is the intermediate wiring interface between EAM analog module and field analog instruments. It connects I/O rack via ribbon cable, field transmitters and analog actuators are wired to screw terminals. It integrates signal fuses, provides circuit overcurrent protection and electrical isolation for analog loops, facilitates field wiring, maintenance and troubleshooting for 4-20mA measurement and control circuits.

InstallationPower off cabinet power and field loop circuit before installation. Mount the assembly on DIN rail. Connect ribbon cable between termination unit and EAM module rack. Wire field analog transmitters to terminal screw blocks. Check wiring continuity and insulation resistance, complete analog loop calibration and function test before online operation.

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

FeatureDedicated EAM analog marshalling termination assembly, integrated fuse protection for each channel, convenient field wiring maintenance, galvanic isolation, Class I Division 2 hazardous area certification. Obsolete legacy spare part, used for APACS+ and QUADLOG analog signal loop maintenance and replacement.

DiagnosticNo analog signal: check ribbon cable connection, blown fuse and loose terminal contact. Signal reading fluctuation: inspect field cable interference, terminal oxidation and loop power supply. Channel fault alarm: verify wire breakage, short circuit and field transmitter fault.

Product BriefSiemens 16191-21 is EAM marshalled termination assembly for APACS+ DCS and QUADLOG SIS, widely used in petrochemical, power and pulp & paper industries for analog instrument signal wiring transition.
