WAGO 750-469

WAGO 750-469 – 2 AI Thermocouple with Diagnostics

Overview

The WAGO 750-469 is a 2-channel thermocouple input module in the WAGO I/O System 750/753. It accepts direct connection of two thermocouples (types K by default, plus optional types S, T, J, E, L, etc.). The module automatically linearizes the entire temperature range and includes cold-junction compensation. Diagnostics include wire break detection with LED indication. Power is supplied from the system side via a 5 VDC source.

Key Features

• Two thermocouple input channels

• Default sensor type K (with options for other types via variation)

• ±120 mV input range (for thermocouple signals)

• Automatic linearization over full measurement range

• Cold-junction compensation for accurate temperature reading

• LED indicator for error (wire break) and for readiness / operation

• Diagnostics features per channel

• Shield contact connected to DIN-rail for improved signal integrity

• Electrically isolated between system supply and measurement
