Description

The digital input module 750-403 receives control signals from digital field
devices (sensors, switches, etc.).
The module is a 2- to 3-conductor device and has 4 input channels. Two
sensors may be directly connected to the module.
As an example, two 3-conductor sensors can be directly connected using
connection 24V, 0V and signal input DI1 or DI2. The connection of more
sensors to signal inputs DI3 and DI4 requires a field side connection module
(750-614) for 24V and for 0V, if need be.
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.
