Features:
- Twelve isolated channels accept three-wire Pt100 or JPt100 sensors.
- One-second input updates deliver steady plant-temperature data.
- Selectable burnout direction defines the open-sensor response.
AAR181-S50 S2 is the requested CENTUM VP FIO isolated RTD input module.
Its measurement circuits compensate three-wire leads and keep individual sensor channels separated.
Confirm suffix, RTD standard, lead resistance, terminal board and burnout action before installation.
AAR181-S50 S2 condition and delivery are confirmed for the requested FIO node.

- Measuring process temperature with isolated three-wire RTD circuits.
- Adding twelve resistance-input channels to a CENTUM VP FIO node.
- Replacing an installed module while retaining the validated terminal board.
- Temperature limits follow the Yokogawa module and node-unit specification.
- Storage conditions must protect connectors and circuitry from condensation.
- Cabinet humidity is controlled so RTD measurements remain stable and insulation is preserved.
- The module is installed inside the specified CENTUM enclosure and node hardware.
- Channel isolation limits interaction between separate field sensor circuits.
- No explosion-protection option is implied by the -S50 basic ordering code.
- Three-wire polarity and paired lead routing are checked at every RTD channel.
- The selected terminal board must be the documented AAR181-compatible type.
- Commissioning confirms burnout direction and sensor indication before control use.
