16 Device Description
WAGO-I/O-SYSTEM 750 XTR
750-537/040-000 8DO 24 VDC 0.5A Diagn XTR
Manual
Version 1.1.1
Do not exceed maximum values via power contacts!
The maximum current that can flow through the power jumper contacts is 10 A.
The power jumper contacts can be damaged and the permissible operating
temperature can be exceeded by higher current values.
When configuring the system, do not exceed the permissible maximum current
value. If there is a higher power requirement, you must use an additional supply
module to provide the field voltage.
Power from SELV/PELV power supply only!
All field signals and field supplies connected to this XTR I/O module
(750-537/040-000) must be powered from SELV/PELV power supply(s)!
In the event of an overload, short circuit or line break, an error bit per channel is
set in the input process image. Using this bit, the master control can identify the
error. After rectifying the error, the error bit is reset in the input image and the
error LED goes off.
The field voltage and the system voltage are electrically isolated from each other.
Use in safety-related applications
When using the I/O module, please observe the notes and connection examples
included in section “Using in Safety Related Applications”.
Any configuration of the output modules is possible when designing the fieldbus
node. Grouping of module types 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.
