Why Choose the ABB DI524 32-Channel Digital Input Module?
The ABB DI524, order code 1SAP240000R0001, is an S500 digital input module providing 32 digital inputs at 24 V DC. Designed for ABB AC500 automation systems, it provides high-density signal acquisition for distributed and centralised industrial control applications.
Each of the 32 inputs uses a 1-wire connection arrangement and is galvanically isolated from the module's I/O bus. Input status is clearly indicated by individual yellow LEDs, allowing operators and maintenance engineers to identify active field signals quickly.
The DI524 supports configurable input delays from 0.1 ms to 32 ms and can provide fast-counter functionality on suitable AC500 configurations, with a maximum counting frequency of 50 kHz. Its 24 V DC Type 1 inputs are suitable for common industrial sensors, switches and control signals.
Key Advantages
- 32 digital inputs: Provides high-density 24 V DC signal acquisition in a single S500 module.
- Flexible input filtering: Input delay can be configured from 0.1 ms to 32 ms to suit different signal conditions.
- Fast-counter capability: Suitable configurations can use two inputs for counting applications at up to 50 kHz.
- Galvanic isolation: The input circuitry is isolated from the rest of the module and I/O bus.
- Individual status indication: One yellow LED per input provides straightforward local signal monitoring.
- Industrial 24 V DC compatibility: Designed for standard PLC field signals and Type 1 input characteristics.
- AC500 system integration: Connects through compatible ABB S500 terminal units for central or decentralised I/O expansion.

High-Density Digital Signal Acquisition for ABB S500
The ABB DI524 provides 32 individual 24 V DC digital inputs for monitoring field devices within an AC500 automation system. The inputs are arranged as one group of 32 channels, with dedicated reference-potential terminals for the process supply. Individual LED indication makes commissioning and fault diagnosis more convenient by providing a direct visual indication of each input state.
For applications requiring faster signal processing, inputs I24 and I25 can be configured for fast-counter operation when the module is used as a suitable central expansion with an AC500 CPU. The DI524 can be installed horizontally or vertically with the applicable thermal derating, while its galvanic isolation and reverse-voltage protection contribute to reliable integration within industrial control cabinets.
Typical Applications
- Industrial PLC digital signal acquisition
- AC500 central I/O expansion
- Decentralised S500 I/O systems
- Push-button and selector-switch monitoring
- Limit-switch monitoring
- Proximity and photoelectric sensor inputs
- Machine status and feedback monitoring
- Conveyor and material-handling systems
- Process automation equipment
- High-speed pulse and counting applications using compatible AC500 configurations
