XBF-TC04RT

Description

4-loop temperature controller module for RTD sensors, offering PID control on-board for up to four independent channels. Integrates with XGB PLCs so you can do closed-loop temperature control inside your PLC rack.

The Polar Energy Assessment:

The TC04RT combines RTD input handling with embedded PID control, alarms, and loop tuning per channel, turning the PLC expansion slot into four compact controllers. It supports standard RTD types and the manual lists PID parameters, autotune options, and alarm outputs. Use it when you want distributed temperature loops without external controllers.

Pros

• Onboard PID for each RTD channel reduces external hardware.
• Alarm outputs and loop tuning options simplify commissioning.

Limitations

• Adds controller complexity inside the PLC; document loop logic and ownership to avoid conflicts.
• Verify RTD ranges and alarm specifications match your process requirements.

Typical use cases

• Furnace, oven, and dryer control where multiple independent PID loops are needed in a single chassis.
