Device Description
The digital input module 750-1415/040-000 (8DI 24VDC 3ms 2-Wire 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 2-wire
sensors.
The sensors are connected to the Push-in CAGE CLAMP
®
connectors DI 1 and
24 V … DI 8 and 24 V.
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 3.0 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 750-1415/040-000 (8DI 24VDC 3ms 2-Wire 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
(750-1415/040-000) 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.
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.
