Key Information
ABB AI562 is an S500-eCo analog input module dedicated to resistance-temperature measurement. Its two configurable inputs are arranged in one group and support Pt100, Pt1000, Ni100 and Ni1000 sensors together with 150 ohm and 300 ohm resistance ranges. The 16-bit conversion architecture and compact removable-terminal design make the module suitable for focused two-channel temperature acquisition without mixing it with the thermocouple functions of AI563.
02
Functions
Acquires two configurable RTD or resistance signals in one channel group.
Supports Pt100, Pt1000, Ni100 and Ni1000 resistance-temperature detectors.
Includes 150 ohm and 300 ohm resistance measuring ranges.
Converts input values with 16-bit resolution including sign.
Uses a green power LED and a red error LED for module-level indication.
Transfers process values through the AC500-eCo I/O bus.

Installation
- Use the required removable 11-pin terminal block; the terminal block is ordered separately.
- Switch off all supply and process voltages before connecting, disconnecting or replacing the module unless all documented hot-swap conditions are satisfied.
- Connect the 24 V DC process supply to UP and ZP and include the process supply in the installation grounding concept.
- Use the ABB connection method for the selected two-, three- or four-wire RTD arrangement.
- When a sensor cable exceeds 20 m, use shielded and grounded cable and provide low-impedance equipotential bonding where required.
- Parameterize each channel for the exact sensor type before checking temperature scaling and diagnostics.
05
Lifecycle
- ABB lists article 1TNE968902R1102 in the Active lifecycle phase.
- The removable terminal block is a separate active ordering item and must be matched to the installed wiring method.
- Retain the exact RTD type, conductor arrangement and scaling when replacing an installed AI562.
- Do not substitute AI563 solely because both modules use 16-bit conversion; their supported sensor families and channel counts differ.
- After replacement, verify open-circuit diagnostics and compare every temperature channel with a known reference.
