2.1.1.2 Description
The digital input module 750-433 receives control signals from digital field
devices (sensors, etc.).
The module has four input channels. Four 2-conductor sensors may be directly
connected to the module.
The sensors can be connected using connection 24 V and DI 1 or DI 2, DI 3,
DI 4.
The connection of 3-conductor sensors to this module requires a field side
connection module (750-604 or 750-614) for 0 V supply.
Each input module has an RC noise rejection filter with a time constant of
0.2 ms.
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.
