• Global Order Number: 1TNE968902R1301
• Channel Count: 4 Analog Inputs / 2 Analog Outputs

Technical Data Specifications

Network Protocol & Deterministic Bus Performance

The AX561 module transfers converted analog values over the internal backplane bus to the CPU processing core. Processing performance supports I/O density scaling and maintaining firmware flash compatibility across controller families. Signal scanning timing integrates deterministic networks capabilities for Profinet / EtherNet/IP distributed I/O architectures.

Delivery Package Items

• 1 x ABB AX561 1TNE968902R1301 Analogue I/O Module

Field Assembly & Cable Termination Rules

• Power Isolation Protocol
  • Isolate the 24 VDC auxiliary power supply prior to mounting or removing the module from the DIN rail base.
• Static Discharge Protection
  • Wear a grounded ESD wrist strap during handling to avoid damaging internal 12-bit converter circuitry.
• Signal Wiring Separation
  • Route 2-wire analog input loops in shielded twisted-pair cables, keeping 200 mm clearance from AC power lines.
• Terminal Grounding Connection
  • Connect cable shields to the main cabinet earthing bar using low-impedance grounding clamps.

Technical Questions & Answers

• Q: What input and output channel configuration is provided on the AX561 module?

  A: The module provides 4 analog input channels configured for 2-wire transmitter loops and 2 analog output channels with 12-bit digital resolution.

• Q: What primary auxiliary voltage supply is required for operational power?

  A: The module requires an external 24 VDC nominal auxiliary power supply to energize onboard loop circuits and logic logic networks.

• Q: Can this analog expansion module be hot-swapped while the CPU backplane is active?

  A: No, module insertion or removal requires complete removal of system 24 VDC power to prevent backplane signal corruption.

• Q: How does I/O density scaling function when adding multiple AX561 units?

  A: Additional modules attach sequentially along the AC500 side-bus interface up to the maximum expansion address limit allowed by the CPU core.

• Q: How is electrical noise suppressed on analog measuring loops?

  A: Twisted-pair shielded cables must be grounded 360 degrees at the entry point of the electrical cabinet to reject field interference.

• Q: What are the physical shipping weight and outer box dimensions?

  A: The packaged module weighs 0.16 kg and measures 13.4 cm in length, 7.3 cm in width, and 4.3 cm in height.

• Q: What operating ambient thermal parameters must be maintained in the enclosure?

  A: Control cabinet interior temperatures must remain within 0 deg C to +60 deg C for normal operational compliance.

• Q: How does firmware flash compatibility affect system expansion?

  A: Matching module hardware revisions to the CPU firmware ensures automatic parameter mapping and predictable bus scan timing.
