ABB 1SAP250500R3001 Analog Input/Output Module

Technical Specifications and I/O Features

The ABB 1SAP250500R3001 analog I/O module, also known as AX561, belongs to the AC500 PLC platform and the S500 I/O family. This module provides 4 analog inputs and 4 analog outputs for comprehensive signal handling in control applications. The inputs support 4-20mA and 0-10V signals, while the outputs deliver 4-20mA signals with 12-bit resolution. The module operates on a 24V DC supply and consumes a typical current of 75 mA. Its compact dimensions measure 67.5 mm x 135 mm x 28 mm (W x H x D), and it weighs approximately 0.14 kg. The module mounts on a compatible terminal base and uses the 1-wire connection technology.

Functional Capabilities and Signal Processing

The 1SAP250500R3001 module actively acquires analog signals from field sensors and converts them into digital values for the PLC processor. Simultaneously, it converts digital setpoints from the controller into precise analog output signals for modulating actuators. The 12-bit resolution ensures accurate representation of process variables for both input and output channels. Furthermore, the module integrates with the S500 terminal base and supports the 1-wire connection system for simplified wiring. The robust design and galvanic isolation protect against electrical noise and ensure reliable operation in industrial environments.

Application Scenarios and System Integration

This analog I/O module suits process control applications requiring a balanced set of inputs and outputs. It integrates seamlessly into AC500 PLC systems for temperature regulation, pressure control, and flow monitoring. The ABB AX561 also serves in HVAC systems and building automation for continuous signal processing. Many system integrators rely on this module for compact, mixed-signal control solutions. Its active product status ensures availability for new projects and system expansions.
