750-537 8DO 24V DC 0.5A, diagnostics
Manual
Version 1.2.0
The I/O module 750-537 (8DO 24V DC 0.5A, diagnostics) 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.
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.
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.
The I/O module 750-537 can be used with all fieldbus couplers/controllers of the
WAGO I/O System 750.
