The Fuji OPC-PT is a PT100 temperature sensor input card designed for the FRENIC-HVAC drive series. It brings a single PT100 RTD channel into the drive's control architecture, letting the drive regulate fan or pump speed based on duct or pipe temperature rather than just a fixed setpoint.
If you are sourcing this for a new FRENIC-HVAC build or as a replacement for a failed card, the OPC-PT is the correct drop-in. The description confirms it is a PT100 temperature sensor input card, so verify your sensor is a three-wire PT100 RTD — not a thermocouple or a two-wire resistive sensor — before wiring.
