Product Introduction
The ABB DI524 (1SAP240000R0001) is a high-performance digital input module designed for use with the ABB AC500 programmable logic controller (PLC) family. It provides a robust interface for reading discrete signals from field devices such as sensors, pushbuttons, and switches. Designed to meet demanding industrial automation requirements, the DI524 offers 16 digital inputs and integrates seamlessly into the AC500 system via a DIN rail-mounted modular form factor.
With wide voltage tolerance, LED channel status indication, and a fast input response time, the DI524 enables precise control and reliable monitoring in automation systems. The module is particularly valued for its ability to support 24 VDC inputs, commonly used in industrial signaling. Whether in process control, factory automation, or utility systems, the DI524 ensures consistent digital input acquisition for real-time logic execution.
