Technical Specifications Module Type: Discrete Digital Output Module Channel Quantity: 16 digital output channels Output Type: Isolated discrete DC output Channel Isolation: Galvanic isolation per output channel Communication: Redundant I/A fieldbus Operating Power: 24 VDC Operating Temperature: 0 °C to +60 °C Storage Temperature: ‑40 °C to +85 °C Relative Humidity: 5%‑95%, non‑condensing Mounting: DIN‑rail baseplate installation Certifications: CE industrial digital output module compliance
Functional Features Sixteen‑channel galvanic‑isolated discrete digital control output. Configurable fail‑safe output state when communication or module fault occurs. Built‑in output channel load fault diagnosis function reports loop abnormal status. Redundant fieldbus communication ensures reliable control command transmission. Hot‑swappable module design for convenient on‑site maintenance replacement.
Application Scenarios Widely used in petrochemical, chemical and power‑plant DCS control cabinets. Outputs interlock control signals to field solenoid valves, intermediate relays, motor auxiliary control loop, completes equipment start‑stop and safety interlock action execution.
Structural Characteristics Compact 200‑series module housing for baseplate mounting. Gold‑plated bottom connector for connection with DIN‑rail baseplate. Front‑panel LED indicators for power, bus communication and channel output status. Matches dedicated termination assembly for field discrete actuator wiring conversion.
Working Principle DCS field control processor sends digital control command to FBM216 module via redundant fieldbus. Internal circuit completes signal isolation and driving, outputs corresponding on‑off status for each channel. Control signal passes through baseplate and termination assembly to field‑site discrete actuators. Module monitors output channel load condition and uploads fault diagnostic information. When communication fails, module executes preset fail‑safe output state.
Installation Requirements Install supporting baseplate on standard 35 mm DIN‑rail inside control cabinet. Insert FBM216 onto baseplate and lock mechanical buckle. Connect field solenoid valve or relay load wiring to matched termination assembly terminals. Complete redundant fieldbus cable connection. Configure channel fail‑safe state parameters in DCS configuration software after power‑on.
