Model Explanation

B872 = 4-channel analog output general series; 200 = Multi-range voltage output configuration type, differences: 000/001 (current), 002 (fixed ±10V), 011/032 (voltage-current hybrid type), 100 (fixed 4-20mA), 200 only outputs voltage and has no current output option. Technical Specifications

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

Optional voltages: 0~5V, 0~10V, ±5V, ±10VDC. Each channel can be independently switched by jumper wires.

Load impedance: 0~5V/±5V ≥ 500Ω; 0~10V/±10V ≥ 1kΩ

Power supply: 5VDC power supply from the rack backplane, no external circuit power supply

Dimensions: 51 (W) × 203 (H) × 279 (D) mm, net weight approximately 0.54kg

Indicators: Green light for module operation, red lights for faults of four independent channels

Operating conditions: Operation: 0~55℃, Storage: -40~85℃, Humidity < 80% RH, no condensation

Accuracy: Full-scale error ≤ ±0.15% FS

Interfaces and matching base

Standard screw terminal base: AS-8535-000, three-wire voltage wiring. Core function

The PLC converts digital quantities into multiple specifications of standard voltage signals, which are used to drive frequency conversion settings, servo speed control, voltage-type regulating valves, and instrument setpoint positions. Applicable scenarios

The power generation, petrochemical, metallurgy and water treatment industries are using the Modicon 984 system. All the on-site points for voltage control equipment have been renovated.

Operation and Maintenance

The modules can be plug-and-play installed in the 800 rack I/O slots. The jumpers inside the board are modified to set the voltage specifications for each channel; the red light on the channel indicates an external line short circuit or the load resistance does not meet the standard; it is compatible with all models B872-001/002/011/032/100 for mixed use in the same rack.
