2.1.1.2 Description
The digital input module 750-440 receives control signals from digital field
devices (sensors, switches, etc.).
The module is a 1-conductor device and has four input channels.
Four 1-conductor sensors may be directly connected to signal input
DI 1, ... DI 4.
The status of the input channels is indicated via status LEDs.
An optocoupler is used for electrical isolation between the bus and the field
side.
Any configuration of the input modules is possible when designing the
fieldbus node. Grouping of module types is not necessary.
Attention
An additional supply module must be added for the field supply with AC
120(230) V!
The supply voltage for the field side is made automatically through the
individual I/O modules by means of power jumper contacts.
Warning
The maximum current of the internal power jumper contacts is 10 A. When
configuring the system it is important not to exceed the maximum/sum
current. However, if such a case should occur, another supply module must be
added.
The digital input module 750-440 can be used with all couplers/controllers of
the WAGO-I/O-SYSTEM 750.
