Model Interpretation

B872: Analog Output Module Series

000: 4-20mA Current Output Specification; 002: Same as current, 200: ±10V/0-10V Voltage Output, 011: Mixed Signal Technical Specifications

Channel: 4 isolated analog outputs, electrical isolation between channels and the backplane

Output signal: 4-20mA DC

Power supply: Backplane 5V bus power supply, external passive output

Dimensions: 51×230×280mm, net weight ≈ 0.6kg

Status: Panel LED channel failure / operation indicator light

Interface configuration

Matching terminal base: AS-8535-000 wiring terminal block, screw terminals connected to on-site regulating valves, frequency converter setpoint signals. Core function

The PLC converts digital signals into industrial standard 4-20mA analog quantities, for controlling and regulating valves, frequency conversion actuators, and setting values of on-site instruments. Applicable scenarios

Chemical industry, water treatment, old power plants, and in-use Modicon 984 DCS/PLC systems for renovation spare parts.

Maintenance and usage

Directly plug and unplug into the 800 series I/O rack slots without configuring hardware jumpers

Troubleshooting: Red LED light = Channel short circuit / Load overload. Power off and recheck the on-site line impedance
