ABB DA501 Distributed Automation I/O Module

Product Overview

The ABB DA501 is a highly versatile digital and analog mixed I/O module designed for the AC500 and AC500-eCo PLC families. This "Distributed Automation I/O" component serves as a multi-functional interface, consolidating 16 digital inputs, 4 analog inputs, 2 analog outputs, and 8 configurable digital I/O points into a single compact footprint.

System Integration and Versatility

The DA501 (1SAP250700R0001) stands out in the AC500 range due to its "universal" analog inputs. Each of the 4 analog channels can be independently configured to handle standard voltage/current signals or direct RTD (Resistance Temperature Detector) inputs, eliminating the need for external signal conditioners. The 8 configurable digital points provide exceptional flexibility, allowing the module to adapt to changing field requirements without hardware swaps. Encased in an IP20-rated housing, the module is optimized for DIN rail mounting inside control cabinets, supporting distributed automation topologies via the FBP (FieldBus Plug) or local expansion bus.
