Siemens 390DM115ACCBN Discrete Output Module

Technical SpecificationsModel:390DM115ACCBN Brand:Siemens Product Type:ODM Discrete Output Module System:APACS+ DCS System Power Supply:24V DC backplane Field Output:115VAC Mounting:MODULRAC rack mount Operating temperature:-20℃ ~ +70℃ Storage temperature:-40℃ ~ +85℃ Relative humidity:5%~95%, non-condensing Weight:2.48kg Dimension:40mm260mm310mm

System compatibility390DM115ACCBN belongs to Siemens Moore APACS+ DCS series. It fits MODULRAC rack, compatible with ACM advanced controller and APACS+ termination assemblies, can coordinate operation with QUADLOG SIS platform.

FunctionThis ODM discrete output module receives control commands from APACS+ controller via backplane bus. It provides 115VAC switching output to drive field AC solenoid valves and auxiliary relays. It supports per-channel circuit monitoring for wire break and short-circuit fault detection, transmits channel diagnostic status back to DCS controller for alarm and maintenance prompt.

InstallationPower off the rack chassis before installation. Insert the module into MODULRAC rack slot and lock the latch, ensure backplane connector fully engaged. Connect ribbon cable between module and marshalled termination assembly, wire 115VAC field actuators to terminal block. Configure channel parameters through APACS engineering software, verify output action and fault diagnosis function before online running.

InterfaceBackplane bus connector, ribbon cable port for marshalling unit, front LED indicators for power, run, fault and individual channel status.

FeatureAPACS+ dedicated 115VAC discrete output module, built-in per-channel fault diagnostics, electrical isolation between system side and field circuit, hot-swappable module, Class I Division 2 hazardous area certification. Obsolete legacy spare part, used for APACS+ DCS AC discrete output control loop maintenance and replacement.

DiagnosticModule no power: check rack 24V DC power supply and backplane contact. Channel no switching output: inspect field wiring, actuator coil continuity and short circuit. Channel fault alarm: check cable breakage, terminal loose contact and field load insulation.

Product BriefSiemens 390DM115ACCBN is APACS+ ODM 115VAC discrete output module, widely used in petrochemical, power and pulp & paper industries for DCS digital control of AC field actuators.
