Technical Specifications

Installation Guidelines

• Power Off: Always disconnect the 24V DC power supply before installing or removing the module. Plugging or unplugging while powered can cause electrical damage.
• Mounting: Designed for standard DIN rail mounting within the AC500-eCo system. Ensure adequate ventilation space around the module.
• Wiring: Connect the 24V DC supply to terminals L+ and M. Use shielded, twisted-pair cabling for analog signals to minimize electromagnetic interference (EMI).
• Grounding: For stable reference potential, interconnect the M terminal to the M/ZP terminal on the CPU or communication interface module.
• Shielding: For cable runs exceeding 20 meters, shielded and grounded cables are mandatory to maintain signal integrity.

FAQ

What is the AX561 1TNE968902R1301?

The ABB AX561 is a compact, S500-eCo series analog I/O module used for process control and industrial automation within the AC500 PLC platform.

How should I connect long cables?

Analog signals are sensitive to electromagnetic interference. If your connection cable exceeds 20 meters, you must use a shielded and grounded cable to ensure accuracy.

Can I remove the module while the system is powered?

No. It is strictly prohibited to plug, unplug, or connect signal terminals while the power is switched ON. Ensure all voltage sources are disconnected before servicing.

How much power does the module consume?

The module requires a 24V DC supply. Power consumption is approximately 5 mA per module added to your CPU or communication interface.
