ABB 3BSE038415R1 SD822 Digital Output Module | 32 CH, 24V DC, 0.5A

ABB 3BSE038415R1 SD822 digital output module. 32 channels, 24V DC, 0.5A per ch, for S800 I/O. High-density output for actuators.

Product: ABB 3BSE038415R1 SD822 Digital Output Module

The ABB 3BSE038415R1 (SD822) is a high-density, 32-channel digital output module for the S800 I/O system within ABB's Extended Automation 800xA. It is designed to control a large number of field actuators, such as solenoid valves, contactor coils, and indicators, with a single module.

Key Features

• High Channel Density:​ Controls 32 discrete outputs in a compact form factor, saving cabinet space.

• Individual Channel Diagnostics:​ Provides per-channel short-circuit and overload detection.

• Redundant Power Supply:​ Supports connection to redundant 24V DC field power supplies for higher availability.

• Flexible Configuration:​ Outputs can be configured for pulse or steady-state operation.

Technical Specifications

Function & Application

The SD822 module receives ON/OFF commands from the 800xA controller and switches the 24V DC field power to the connected loads. Its high channel count makes it ideal for applications requiring control of numerous on/off devices from a centralized I/O rack, such as in valve manifolds or large machinery.

Typical Applications

• Controlling solenoid valves in process plants.

• Operating contactor coils for motors and heaters.

• Driving pilot lights and indicators on control panels.

• Batch processing and material handling systems with many discrete actuators.

Critical System & Wiring Note

This is a sourcing (PNP) output module, meaning it provides 24V DC​ when active. It must​ be connected to sinking inputs​ on field devices or to the positive side of a load, with the load's other side connected to 0V DC.

It requires:

• An S800 mounting unit​ (e.g., TU847) for installation.

• A communication interface module​ (e.g., CI854, CI867) in the same rack.

• External 24V DC field power supplies​ (single or redundant).

• Configuration within the 800xA Engineering Workplace.
