Device Description

The digital input module 753-431 (8DI 24V DC, 0.2ms) 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
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.
Connection examples are shown in section "Connecting Devices" > ... >
"Connection Example(s)".
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".
The assignment of the connections is described in the "Connectors" section.
Connection examples are shown in section "Connecting Devices" > ... >
"Connection Example(s)".
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 753-431 (8DI 24V DC, 0.2ms) 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 current via power jumper contacts!
The maximum current to flow through the power jumper contacts is 10 A.
Greater currents can damage the contacts.
When configuring your system, ensure that this current is not exceeded. If
exceeded, insert an additional supply module.
