750-407/040-000 2DI 220V DC 3.0ms XTR
Do not exceed maximum current via power contacts!
The maximum current to flow through the power jumper contacts is temperature
dependent:
• Up to 60 °C: 10 A
• From 60 °C: 8 A
Greater currents can damage the power contacts. When configuring the system,
do not exceed this current. If that is the case, you must use an additional supply
module.

With consideration of the power jumper contacts, the individual modules can be
arranged in any combination when configuring the fieldbus node.
An arrangement in groups within the group of potentials is not necessary.

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).

Increased interference!
For standard-compliant application in substation instrumentation and control,
telecontrol systems, railway technology or shipbuilding certified operation,
field-side power supply filter 750-624/040-001 or power supply filter
750-626/040-000 are generally to be used for XTR module groups.

The I/O module can be operated with all fieldbus couplers/controllers of the
WAGO-I/O-SYSTEM 750 XTR.
Observe the instructions for mixed operation when used in mixed operation
behind standard fieldbus couplers/controllers.
