Technical Specifications Standard 4‑20 mA analog output channels. Back‑plane PLC system bus interface. Auxiliary power 24 V DC, typical power consumption 3.2 W. Operating temperature 0 ℃ to +60 ℃, storage temperature ‑40 ℃ to +85 ℃, non‑condensing relative humidity 5%‑95%. Channel‑wise galvanic isolation.
Functional Features Receives digital control values from PLC main controller via back‑plane bus. Completes digital‑analog conversion and outputs standard 4‑20 mA analog signals to field regulating devices. Front‑panel LED indicators display module running and fault status. Built‑in hardware self‑diagnosis detects output loop short‑circuit and internal circuit faults.
Application Scenarios Analog output spare part for ABB 07 series PLC control rack. Applied in industrial process‑control cabinet reconstruction and maintenance.
Performance Parameters High‑precision digital‑analog conversion performance. Stable analog signal output capability. Reliable output loop fault detection function.
Material Composition Flame‑retardant plastic module housing. Multilayer glass‑fiber epoxy printed circuit board. Digital‑analog conversion and signal isolation assemblies. Back‑plane plug‑in connector and field signal screw terminals.
Structural Characteristics Standard PLC rack plug‑in module. Front side fitted with field analog signal terminals and status LED indicators. Rear side equipped with back‑plane bus connector. Weight approximately 0.33 kg.
Working Principle Internal digital‑analog conversion circuit converts digital data into 4‑20 mA analog current signals, which are sent to field actuators. Diagnosis circuit monitors output loop load state and module hardware condition continuously.
Installation Requirements Insert GJR5252300R3101 07AC91F into corresponding rack slot and lock fixing latch. Connect field actuator wiring to front‑end signal terminals. Confirm back‑plane connector is fully engaged. Restore power supply, calibrate analog output channels and verify field actuator adjustment response.
Usage Notes Match field equipment load impedance with module output specification. Prevent output channel short‑circuit damage. Hot‑plug under powered state is prohibited. Perform channel calibration after module replacement.
