ABB 1SAP240000R0001 DIN Rail Mounted Safety Relay Module

The ABB DI524:S500 Digital Input Module is a 32-channel, 24 V DC DIN-rail mounted input block that belongs to ABB's S500 distributed automation I/O family; it uses a 1-wire input architecture to convert field signals into a 24 V DC digital stream for the controller. Designed for line-powered sensing, the DI524 measures 68.0 mm wide, 76.0 mm high, and 63.0 mm deep, weighs about 0.110 kg, and mounts on a TH35-15 DIN rail per IEC 60715, with IP20 protection and RoHS compliance. A 24 V DC supply is required, and the 32 digital inputs accept standard 24 V signals from sensors and switches, enabling straightforward wiring with removable terminal blocks for quick field installation. In ABB control ecosystems, this module is commonly programmed and integrated using AC500 Control Builder, supporting distributed I/O configurations that simplify cabinet wiring and scalable automation projects.
