Features:
- RTD measurement: Eight channels accept the ABB-listed RTD and resistive sensor types.
- Three-wire connection: All RTDs must be isolated from ground.
- Channel diagnostics: ABB documents open-circuit, short-circuit, and grounded-sensor monitoring.
This A revision identifies the current eight-channel RTD input ordering configuration with article number 3BSE040662R1.
The module linearizes supported resistance sensors, converts temperature units, and allows individual channel and mains-filter configuration.
Match the sensor curve, three-wire cable, grounded-sensor rule, MTU, mechanical key, and engineering settings before installation.
Availability is subject to Apter Power inventory and sourcing confirmation.

Three-wire connection checks
- Lead arrangement: Keep the three conductors assigned exactly as shown in ABB wiring data.
- Ground isolation: Confirm every RTD is isolated from ground.
- Cable resistance: Review lead resistance and conductor balance.
- Shielding: Terminate shields according to the cabinet EMC plan.
Resistance-sensor selection
- Sensor curve: Select the configured Pt100, Cu10, Ni100, Ni120, or resistance input.
- Channel setup: Configure each used channel individually.
- Temperature units: Confirm Celsius or Fahrenheit conversion in the engineering database.
- Mains filter: Match the 50 or 60 Hz setting to the site supply.
RTD fault review
- Open circuit: Check terminal tightness and all three conductors.
- Short circuit: Inspect sensor leads and terminal bridges.
- Grounded sensor: Test insulation from the RTD circuit to ground.
- Reference fault: Review module diagnostics and the approved maintenance procedure.
