16 Device Description
WAGO-I/O-SYSTEM 750 XTR
750-652/040-000 Serial Interface RS-232/RS-485 XTR
Manual
Version 1.3.0
firmware version 03 or higher and as a DMX receiver with firmware version 06 or
higher.
The wiring to the communication partner takes place in RS-232 mode via the TxD,
RxD connections, if necessary RTS/CTS and ground and in the RS-485/
RS-422 mode via the connections A, B, X, Y, and ground.
The shield connection is fed directly to the carrier rail and contact is made
automatically by snapping the module onto the rail.
The assignment of the connections is described in the “Connectors” section.
Connection examples are shown in section “Connect Devices” > … > “Connection
Example(s)”.
Multi-color LEDs indicate the operating status and the trouble-free local bus
communication as well as the status of the signal transmission.
The meaning of the LEDs is described in the “Display Elements” section.
The I/O module 750-652/040-000 (Serial Interface RS-232/RS-485 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.
The field voltage and the system voltage are electrically isolated from each other.
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.
