Device Description
The digital input module 750-1418 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 input signals are connected to the CAGE CLAMP
®
connections DI 1 and 0V
... DI 8 and 0V.
The assignment of the connections is described in the "Connections" section.
Each input channel has an RC noise rejection filter with a time constant of 0.2 ms.
The I/O module inputs provide low-side switching. If the 0V 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 receives the 24V voltage supply for the field level from an
upstream I/O module or from the fieldbus coupler/controller via the power
contacts used as blade contacts. It then provides this potential to subsequent I/O
modules via the power contacts used as spring contacts.
Do not exceed maximum current via power contacts!
The maximum current to flow through the power contacts is 10 A.
Greater currents can damage the power contacts.
When configuring the system, ensure that this current is not exceeded. If
exceeded, an additional potential feed module must be used.
Use potential feed module for Ground (earth)!
The I/O module has no power contacts for PE intake and transfer. Use a potential
feed module when a PE feed is needed for the subsequent I/O modules.
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 750-1418 can be used with all fieldbus couplers/controllers of the
WAGO-I/O-SYSTEM 750.
