G6F-TC2A

Description

A 4-channel thermocouple (T/C) input module for Master-K / GLOFA PLCs. Supports many TC types (K, J, E, T, B, R, S) and can read from -200 °C up to 1800 °C depending on type.

The Polar Energy Assessment:

G6F-TC2A enables your PLC to read temperature via thermocouples. It offers automatic cold-junction compensation, burn-out detection per channel, and 12- or 14-bit digital conversion (per LS documentation) into a 0–16,000 range. The conversion speed is 50 ms per channel. This module is great when you need reliable temperature measurement integrated directly into your PLC without external signal conversion.

Pros

• Supports a wide range of thermocouple types (K, J, E, T, B, R, S)
• Automatic reference-junction compensation: simpler wiring & more accurate readings.
• Burn-out detection on every channel: helps detect sensor faults.
• Four channels per module: good density for temperature measurement tasks.

Limitations

• Conversion speed (50 ms/channel) may be slow for very fast thermal changes.
• Needs correct scaling / calibration in the PLC to convert counts to °C.
• Thermocouples themselves need careful handling (wiring, shielding, compensation).

Typical use cases

• Temperature monitoring in process control (furnaces, ovens, chemical processes)
• Quality control in manufacturing where multiple TCs are needed
• Systems that need integrated temperature feedback into PLC logic (alarms, PID loops)
