Model Explanation

B872 = 4-channel analog output module series; 002 = ±10VDC bipolar voltage output specification, distinction: 000 (4-20mA), 001 (0-20mA), 200 (0-10V unipolar voltage). Technical Specifications

Channels: 4 channels are electrically isolated from each other and separated from the backplane and the field side.

Output specifications: DC -10V to +10V standard industrial voltage signal.

Power supply: 5VDC bus power supply from the rack backplane, no active load at the field side.

Dimensions: 51 (W) × 203 (H) × 279 (D) mm, net weight approximately 0.6kg

Indicators: Red light for single-channel failure, green light for module operation status

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

Interfaces and matching base

Standard wiring base AS-8535-000 with screw terminal blocks, external connection for servo setpoint, variable frequency speed regulation, and voltage-type regulating valve actuator. Core function

The digital quantity of the PLC is converted into ±10V analog voltage, enabling continuous control output for the valves in the forward and reverse directions as well as the bidirectional speed regulation equipment. Applicable scenarios

Replacement of old Modicon 984 control system spare parts for power plants, chemical plants, metallurgy, and water treatment.

Operation and Maintenance

The entire unit can be directly plugged and inserted into the 800 series I/O slots without the need for hardware jumpers; when the channel indicator light is on, it indicates an external line short circuit or low load impedance, and power failure should be investigated by checking the on-site wiring; modules of different specifications such as 000/001/002 B872 can be mixed and installed on the same chassis.
