Model Explanation

B872: 4-channel analog output module series

001: 0-20mA DC current output specification; 000 = 4-20mA, 002 = ±10V voltage, 200 = 0-10V, 011 = voltage + current mixed output. Technical Specifications

Channel: 4 independent and isolated analog outputs, with electrical isolation between the channel and the backplane

Output signal: DC 0-20mA standard industrial current signal

Power supply: 5VDC bus power supply from the backplane of the rack, passive output at the site side

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

Status: Panel single-channel fault LED indicator, operation indicator light

Operating temperature: 0-60℃, storage -40-85℃

Interface and matching base

Matching terminal base: AS-8535-000 screw-fixed terminal block, with external control valve, frequency converter setpoint, and on-site actuator control lines. Core function

The internal digital quantities of the PLC are converted into 0-20mA analog signals, which are used for remotely adjusting the valve opening, the speed of the frequency converter, and the set values of the on-site instruments. Applicable scenarios

Renovation and replacement of spare parts for old chemical plants, power plants, water treatment facilities, and metallurgy using Modicon 984 PLC.

Operation and Maintenance

Direct hot-swappable installation into the 800 series I/O rack slots, no need for hardware jumpers;

Red light alarm = corresponding channel line short circuit, load impedance exceeds standard, power off for troubleshooting external lines;

The same rack can accommodate 000/001/002 different output type B872 modules.
