ABB AO561 Analog Output Module

Product Overview

The AO561 (1TNE968902R1201) is a compact analog output module developed for the ABB AC500-eCo PLC platform. It delivers two independently configurable analog output channels capable of operating in either voltage or current mode. The module is intended for accurate analog signal generation in distributed control architectures where space efficiency, signal stability, and system compatibility are essential.

Designed as part of the S500-eCo I/O family, the AO561 supports 1-wire analog outputs and integrates directly into AC500-eCo controller stations without additional interface hardware.

Core Functional Capabilities

The AO561 provides flexible output configuration, allowing each channel to be set individually for voltage or current operation. With 12-bit digital resolution and galvanic isolation from the system bus, the module ensures stable signal transmission and reliable operation in electrically noisy industrial environments.

Its pluggable terminal design simplifies wiring and maintenance, while the slim DIN-rail housing supports high-density cabinet installations.
