Device Description
The digital input module 750-431/040-000 (8DI 24 VDC 0.2ms XTR) receives
control signals from digital field (e.g. of sensors, transmitters, switches or
proximity switches).
The I/O module has 8 input channels, providing a direct connection to 1-wire
sensors.
The sensors are connected to the following CAGE CLAMP
®
connectors:
DI 1 … DI 8.
Use field side connection modules!
Where required, use the appropriate field side connection modules for power
supply to the sensors.
The assignment of the connections is described in the “Connectors” section.
Each input channel has a RC noise rejection filter with a time constant of 0.2 ms.
The I/O module inputs provide high-side switching. If the 24 V potential for field
power is switched to an input connection, the signal status for the corresponding
input channel is set to “high”.
A green LED indicates the switched status of each channel.
The meaning of the LEDs is described in the “Display Elements” section.
The I/O module 750-431/040-000 (8DI 24 VDC 0.2ms 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.
Power from SELV/PELV power supply only!
All field signals and field supplies connected to this XTR I/O module
(750-431/040-000) must be powered from SELV/PELV power supply(s)!
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.
