XBF-RD04A

Description

4-channel RTD temperature input module for the XGB family, supporting Pt100 and JPt100 sensors with 14-bit A/D resolution. Removable terminal block and standard XGB mounting make it plug-and-play for existing racks.

The Polar Energy Assessment:

The RD04A lets the PLC read four RTD sensors (Pt100 / JPt100) with good resolution for process and machine control. It follows LS Electric’s XGB module power and wiring conventions and includes per-channel status LEDs and recommended wiring details in the datasheet. Use it when you need accurate temperature feedback from RTDs without adding external signal conditioners.

Pros

• Solid RTD support (Pt100 / JPt100) and 14-bit resolution for reliable temperature control.
• Compact 4-channel pack saves expansion slots and wiring.

Limitations

• RTD-only module; thermocouples need a separate TC module.
• Requires careful wiring and cold-junction handling typical of RTD circuits.

Typical use cases

• Oven and chamber control, process monitoring, and machine temperature feedback where RTD accuracy matters.
