Model Explanation

B872 = 4-channel analog output module body series; 011 = Channel jumper selectable mixed-type output, differences: 000 (4-20mA), 001 (0-20mA), 002 (±10V), 200 (0-10V), 011 Single-channel hardware jumper switch between voltage/current signals. Technical Specifications

Channels: The 4 channels are isolated from each other, and the backplane power supply is electrically isolated from the on-site load.

Optional output specifications: 4~20mA, 0~20mA, 0~10VDC, ±10VDC. Each channel has an independent jumper selection.

Power supply: 5VDC power supply from the rack backplane, passive output at the on-site side.

Dimensions: 51 (W) × 264 (H) × 211 (D) mm, net weight approximately 1.2kg

Indicators: Four independent channel failure red lights, module operation green lights

Operating environment: Operating temperature 0~60℃, storage temperature -40~85℃, humidity ≤ 80% RH without condensation

Interface and matching base

Standard wiring terminal base AS-8535-000 with screw terminal wiring, single card terminals compatible with both voltage and current external wiring. Core function

The digital quantities of the PLC can be flexibly converted into current/voltage analog signals through onboard jumpers. The same module can simultaneously drive various types of on-site equipment such as control valves, servo setpoints, and variable frequency speed regulation. Applicable scenarios

For the renovation and replacement of old Modicon 984 PLCs in chemical plants, power plants, metallurgy, and water treatment facilities, where the signal types of on-site instruments are mixed, this is the preferred choice for the renovation project.

Operation and Maintenance

The modules can be directly plugged and installed into the 800 series I/O slots. The output type of the channels can be switched by the small jumpers on the board; the red light of the corresponding channel is on when there is an external line short circuit or abnormal load impedance; the rack can be mixed and used with all models of the B872 series modules.
