The digital input modules convert the external binary signals from the process to the internal signal level of the programmable controllers.

Digital input modules are available with 8, 16 or 32 in puts and for a range of input voltages. The modules require 1/2 or 1 slot (depending on the subrack).

The modules comprise:
- Green LEDs for indicating signal status
- Enable input F (434 4 digital input module for NAMUR sensors only) for disabling input signals.
- Relay contact (MELD) and 24 V input (RESET) for interrupt processing. The signal leads must be connected with front connectors. They can be labelled in the fields next to the LEDs.

Enable input
Digital input 434 4 only:
The input signals can be dis abled by means of enable input F. This enable input can be deactivated by removing a jumper on the module.

Interrupt processing
Digital input 434 7 only:
A group signal generates an interrupt in the CPU when a particular input signal changes. The group signal drives a latching relay on the module (the relay contact MELD is accessible from the front panel), which can be reset via a 24 V input (RESET).
In the user program the user can specify for each input whether the interrupt is to be set by the positive or negative going edge. If interrupt processing is not essential, the 434 7 module can be used in any type of subrack. Interrupt evaluation by the 434 7 digital input module is only possible in a central controller. The module takes up two bytes for input addresses and two bytes for output addresses.
Interrupt evaluation is only possible in an expansion unit (ER 701 3 subrack) which is connected using the IM 307 and IM 317 interface modules and if the 432 4 digital input module (S5 135/ 155U) is used in the expansion unit instead of the 434 7 digital input module generating the interrupt.

All digital input modules of the S5 135U/ 155U pro grammable controllers can be used in the S5 115U with adapter casings. The 434 4 digital input module requires an adapter casing.
