ABB DC532 S500 Digital Input/Output Module – 1SAP240100R0001

The ABB DC532, product number 1SAP240100R0001, is a high-density digital input/output module for the ABB AC500 / S500 PLC platform. It is designed for industrial automation, machine control, factory automation and distributed I/O applications.

The DC532 combines 16 dedicated 24V DC digital inputs with 16 configurable digital channels that can be configured as either digital inputs or transistor digital outputs. This provides up to 32 digital input channels when all configurable channels are used as inputs.

16 Dedicated Digital Inputs

The module provides 16 fixed digital input channels for connecting common 24V DC industrial field devices such as proximity sensors, limit switches, push buttons, selector switches and other digital control signals.

16 Configurable Digital I/O Channels

In addition to the 16 dedicated inputs, the DC532 provides 16 configurable digital channels. These channels can be configured as digital inputs or digital outputs according to the requirements of the automation application.

This flexible architecture makes the module useful for machines where the required balance between input and output signals may vary.

24V DC / 0.5A Transistor Outputs

When the configurable channels are used as digital outputs, they operate as 24V DC transistor outputs rated up to 0.5A, subject to the module's electrical, thermal and group-loading limits.

Fast Counter Functionality

The DC532 includes integrated fast-counter functionality. ABB specifies support for up to two fast counters at up to 50kHz, making the module useful for applications involving pulse signals and higher-speed digital counting.

Flexible S500 I/O Architecture

The DC532 belongs to ABB's modular S500 I/O family. S500 modules can be used for local I/O expansion with compatible AC500 CPUs or in compatible remote/distributed I/O configurations.
