Product Details
The ABB AX561 1TNE968902R1301, also cataloged as the AX561 Analog Input/Output Module, operates as a dedicated hardware component for analog signal processing and field device control within ABB S500 and AC500-eCo I/O platforms. The module manages 4 analog inputs and 2 analog outputs configured for voltage or current loops using a 1-wire connection scheme. It converts incoming analog field variables into 12-bit digital values while driving proportional control signals to field actuators.

Deterministic I/O Density Scaling and Firmware Flash Compatibility
The AX561 module scales analog I/O density within compact DIN-rail mounting footprints, executing continuous signal updates across the S500 expansion bus. Integrated firmware flash compatibility across AC500-eCo CPU processors ensures automatic parameter assignment during rack initialization. High-velocity backplane communication prevents data transmission latencies, maintaining deterministic execution for 12-bit conversion cycles on both input acquisition and output command channels.
Frequently Asked Questions
Q: What resolution is provided on the analog channels of the AX561 module?
A: Both the 4 analog inputs and the 2 analog outputs feature a 12-bit analog-to-digital / digital-to-analog signal conversion resolution.
Q: Can the AX561 channels be hot-swapped while the CPU is executing logic?
A: No. Power to the CPU terminal base and process voltage supply must be isolated prior to removing or seating the module to avoid bus communication faults and hardware damage.
Field Installation Guidelines
- Mount the AX561 onto the S500/AC500-eCo terminal base unit on a standard 35 mm DIN rail, pushing until the locking latch firmly clicks.
- Verify that all field wiring for voltage (U) or current (I) loops is de-energized before inserting conductors into the pluggable terminal blocks.
- Keep analog signal cables physically separated from high-voltage AC lines and switching inductive loads by a minimum distance of 200 mm.
- Ground all shielded twisted-pair cables at a single point near the panel entry point to eliminate potential ground loop interference across 12-bit resolution channels.
- Confirm that the terminal block screws are torqued to 0.5 Nm to maintain secure mechanical and electrical contact.

Tech & Buying Guide
Understanding Marshalling Cabinets in Industrial Control Systems Architecture
Industrial control system deployments rely on structured signal distribution to bridge field instrumentation with central processing hardware. A marshalling cabinet serves as the vital intermediate connection point between heavy field home-run multi-pair cables and delicate input/output (I/O) modules housed inside Programmable Logic Controller (PLC) or Distributed Control System (DCS) enclosures. By segregating field cable terminations from control hardware, engineers maintain system flexibility, safeguard controller components, and streamline commissioning workflows.
FAT vs SAT in Industrial Control Systems: Key Differences and Execution Guide
Industrial control system deployment relies on strict verification protocols to guarantee operational safety, system stability, and regulatory compliance. Commissioning complex Programmable Logic Controller (PLC) racks, Distributed Control Systems (DCS), and Safety Instrumented Systems (SIS) requires two critical milestones: the Factory Acceptance Test (FAT) and the Site Acceptance Test (SAT). Both procedures validate that system automation meets design specifications, but they occur at different stages of project execution and target distinct operational risks.
Hub vs Switch vs Router in Industrial Automation Architecture
Modern factory automation relies on reliable industrial networking infrastructure to exchange real-time field data across operational technology systems. Engineers often encounter networking hardware like hubs, switches, and routers when integrating Programmable Logic Controllers, Distributed Control Systems, and SCADA monitoring nodes. Although these devices share physical ports, they operate at different layers of the Open Systems Interconnection reference model and deliver distinct traffic management capabilities.
