Analog input adapter for FX3U
The FX3U-4AD-PNK-ADP is a four-channel analog temperature input adapter for the FX3U PLC series, accepting Pt1000 and Ni1000 RTDs in 2- or 3-wire configuration with a resolution of 0.1. Each channel returns a digital value over the compensated range: -500 to +2500 for Pt1000 (covering -50 °C to +250 °C) and -400 to +1100 for Ni1000 (covering -40 °C to +110 °C). The 0.1 resolution means a step of 0.1° per digit, giving 0.1 °C readability on both sensor types.
Sourcing and lifecycle
The FX3U-4AD-PNK-ADP carries a mature lifecycle stage. That means it is an established current-production item with stable supply. Typical lead time runs 1–10 working days when ordered against an RFQ.
Integration notes
Mounts as an expansion adapter on an FX3U base unit via the dedicated connector. The 2/3-wire input per channel allows 2-wire RTD connection (with compensation) or 3-wire for lead-resistance cancellation. The adapter draws its power from the base unit; no external supply needed.
