ABB AX522 1SAP250000R0001 AC500 Analog I/O Module

Product Overview

The ABB AX522 (1SAP250000R0001) functions as a high-density analog expansion component within the AC500 Distributed Automation I/O family. This module integrates 8 multi-mode analog inputs and 8 analog outputs into a single slim-line housing, providing a versatile interface for complex process control. It supports a diverse array of signal types including Voltage (U), Current (I), and Resistance Temperature Detectors (RTD), alongside digital input capabilities. We supply this module as 100% Brand New and Original, ensuring your industrial control loops utilize factory-certified hardware for high-precision data acquisition.

Technical Specifications

• Resolution: 13-bit (Input and Output)

• Input Signal Types: Voltage, Current, RTD (e.g., Pt100, Pt1000), Digital Input

• Output Signal Types: 4 Channels support Voltage/Current; 4 Channels support Voltage only

• Supply Voltage: 24 V DC (20.4 … 28.8 V DC range)

• Power Consumption: 3.648 W (@Pcons)

• Degree of Protection: IP20 (Housing)

• Operating Temperature: 0 °C to +60 °C (Horizontal mounting)

• Dimensions: 67.5 mm (W) x 76 mm (H) x 62 mm (D)

Engineering Advantages

• Unrivaled I/O Density: By packing 16 total analog points (8 in/8 out) into a 67.5 mm width, the AX522 significantly reduces the required DIN rail space. This high-density architecture allows engineers to expand system capabilities without upgrading to larger, more expensive control cabinets.

• Multi-Signal Input Versatility: Each of the 8 input channels independently supports Voltage, Current, and RTD signals. This flexibility eliminates the need for separate specialized modules, simplifying the bill of materials (BOM) and reducing spare parts inventory.

• High-Resolution Precision: 13-bit conversion ensures the PLC receives granular data from field sensors. This resolution provides the accuracy necessary for sensitive pressure, flow, and thermal control loops in advanced manufacturing and process industries.

• Flexible Installation Topography: The module supports both horizontal and vertical mounting on standard TH35-15 DIN rails. This versatility accommodates various enclosure layouts, though users must apply appropriate derating for vertical installations to maintain thermal stability.

• Direct I/O Bus Integration: The AX522 connects seamlessly via the internal I/O bus to AC500 CPUs or decentralized bus couplers. This direct link ensures high-speed data throughput and instantaneous diagnostic feedback through the AC500 Control Builder software.

FAQs

• Does the AX522 require a specific Terminal Base?

  Yes. You must mount the AX522 on a compatible S500 Terminal Base (such as the TU515 or TU516). The base handles the 24V DC power distribution and the physical field wiring, allowing for hot-pluggable module replacement without disturbing cable connections.

• Can I use the analog inputs as digital inputs?

  Yes. The AX522 allows the configuration of analog inputs as digital inputs. This feature provides additional flexibility when your project requires a mix of analog sensing and simple limit switch monitoring on the same module.

• What is the maximum operating altitude for this module?

  The AX522 maintains full operational specifications up to an altitude of 2000 meters. For installations exceeding this height, please contact our technical team for specific atmospheric pressure and cooling guidelines.

• How does the module handle RTD temperature scaling?

  The module processes RTD signals (like Pt100 or Pt1000) directly. You configure the sensor type in the AC500 Control Builder software, which then handles the linearisation and converts the resistance into a temperature value accessible by the PLC logic.
