Technical Specifications Module Type: 8‑Channel Analog Output Module Channel Quantity: 8 analog output channels Output Signal: 4‑20 mA DC analog output Channel Isolation: Galvanic isolation between each output channel Communication Interface: 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 analog output module compliance
Functional Features Eight‑channel isolated 4‑20mA analog control signal output. Output hold function keeps last output value when fieldbus communication fails. Built‑in channel load fault diagnosis, detects open‑loop load abnormal status. Redundant fieldbus communication with automatic master‑standby switching. Hot‑swappable module structure for on‑site replacement without disconnecting field wiring.
Application Scenarios Applied in petrochemical, chemical and water‑treatment DCS control cabinets. Outputs analog control signal to regulating valves, variable‑speed actuators, completes flow, pressure and liquid‑value closed‑loop adjustment control.
Structural Characteristics Compact 200‑series module housing, hardware part number P0916JT. Gold‑plated bottom connector for electrical connection with DIN‑rail baseplate. Front‑panel LED indicators for power, bus communication and channel fault alarm. Cooperates with matched termination assembly for field analog output wiring conversion.
Working Principle DCS field control processor sends digital control command to FBM211 P0916JT module via redundant fieldbus. Internal D/A conversion circuit converts digital command into 4‑20mA analog output signal. Analog signal passes through baseplate and termination assembly to field actuators. Module monitors channel load status and uploads fault diagnostic information. When bus communication is interrupted, output hold function maintains last valid output value.
Installation Requirements Mount matched baseplate on standard 35 mm DIN‑rail inside control cabinet. Insert FBM211 P0916JT onto baseplate and lock mechanical buckle. Connect field analog actuator wiring to corresponding termination assembly terminals. Complete redundant fieldbus cable connection between baseplate and control processor. Set channel output parameters in DCS configuration software after power‑on.
