Device Description
The field-side connection module 750-1606/040-000 is used in combination with
the 16-channel digital output modules (e.g. 750-1515/040-000) or the 8-channel
output modules with 1-wire connection to provide the 0 V potential for the
outputs.
This does away with the need for additional rail-mounted terminal blocks.
The 0 V power supply for the field level is provided to the Push-in CAGE
CLAMP
®
connectors 1 … 16.
The assignment of the connections is described in the “Connectors” section.
The I/O module 750-1606/040-000 (Potential Distribution 16*0V XTR) receives
the 24 V voltage supply for the field level from an upstream I/O module or from
the fieldbus coupler/controller via blade-formed power jumper contacts. It then
provides these potentials to subsequent I/O modules via spring-formed power
jumper contacts.
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.
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.
