ABB DA501 1SAP250700R0001 Digital Analog Module

Product Overview

The ABB DA501 (Part Number: 1SAP250700R0001) is a high-density, multi-functional S500 Digital/Analog I/O Expansion Module designed for AC500 PLC automation systems. Consolidating comprehensive signal processing into a compact DIN-rail footprint, this versatile module provides 16 digital inputs (24 VDC), 4 analog inputs (Voltage, Current, RTD), 2 analog outputs (Voltage, Current), and 8 configurable digital I/O channels (24 VDC 0.5A). Weighing only 0.121 kg (0.27 lbs), the DA501 optimizes panel space and offers exceptional 13-bit signal resolution for complex process control applications.

Core Technical Advantages

Hybrid I/O Integration: Merges digital, voltage, current, and RTD temperature signals onto a single card, drastically reducing total system hardware footprint.

Flexible Configurable Channels: Features 8 field-configurable digital channels that can function independently as inputs or transistor outputs (0.5A).

High Resolution Precision: Delivers 13-bit resolution across both analog input and output loops for highly accurate industrial sensor acquisition and control.

Technical Specifications

Installation and Maintenance

DIN Rail Mount: Snap the DA501 module onto the S500 terminal base on standard 35mm DIN rail until the locking mechanism fully engages with adjacent CPU or I/O cards.

Wiring & Powering: Connect field signals according to channel assignments. Ensure the main 24 VDC supply voltage remains within the safe 20.4 V to 28.8 V DC operating tolerance.

Engineering Advantages

Compact High-Density Channel Design

With up to 30 combined I/O points in a single ultra-compact housing, the DA501 dramatically slashes cabinet real estate demands while lowering overall system wiring costs.

Universal Sensor Compatibility

Direct support for process instrumentation including RTD temperature sensors, 0-10V, and 4-20mA devices eliminates the need for third-party signal converters or extra power supplies.

Flexible Process Field Adaptation

The configurable digital channels allow automation engineers to adjust field I/O configurations dynamically without changing hardware or adding additional expansion blocks.
