Device Description

3
The 750-469/040-000 analog input module allow thermocouples be measured in
the field. It can also be used to measure voltages (mV). Depending on the
operating mode, the voltage value is converted to a temperature or is directly
send out by the module. A microprocessor within the module is used for
converting and linearizing the measured voltage value into a numeric value
proportional to the temperature of the selected thermocouple.
The operating mode can be set by parameterization using the WAGO-I/O-
CHECK start-up and diagnostic tool (Item No.: 759-302). The default setting is
thermocouple of type K.
The analog module has 2 input channels allowing the direct connection of 2
thermocouples.
For example, 2 thermocouples can be connected either to the CAGE CLAMP
connectors +TC 1 and −TC 1 or to +TC2 and −TC 2.
The shield connection is fed directly to the carrier rail and contact is made
automatically by snapping the module onto the rail.
The field voltage and the system voltage are electrically isolated from each other.
The assignment of the connections is described in the "Connectors" section.
The operational readiness and the trouble-free local bus communication of the
channels are indicated via a green function LED.
A red fault LED per channel indicates a wire break or that the signal is outside
the measuring range.
The meaning of the LEDs is described in the "Display Elements" section.
Use a power supply module!
Use a power supply module for field-side power supply of downstream I/O
modules.
Mixed operation
Mixed operation (standard/XTR modules) within a node is possible when groups
of modules are electrically isolated on the field side (i.e., electrically isolated
power supply).
