6ES5430-4UA11 - Digital Input Module - SIEMENS
SIMATIC S5.430 DIGITAL INPUT MODULE FLOATING 32 INPUTS, DC 24V COMPACT VERSION U.
This SIEMENS digital module is at your disposal in supply to replace your defective equipment and has a guarantee adapted to your needs.
The digital input modules con vert the external binary sig nals from the process to the internal signal level of the pro grammable controllers.
Digital input modules with 32, 16 and 8 inputs for a range of input voltages are available. The modules require either one or two slots.
Front connectors are used for terminating the signal cables. Both modules and front connectors may be inserted and removed under power.
Green LEDs indicate the sig nal status of the inputs.
Adhesive labels are supplied to identify the modules and front connectors.
Enable input :
The input signals can be dis abled by means of the enable input F. This enable input can be deactivated by removing a jumper on the module.
Interrupt processing :
The 432 4 digital input module generates an interrupt when an input signal changes:
- In the central controller, an interrupt line is provided for each CPU. Modules must be plugged into the central controller.
- The CPU 948 has a mode of operation available which recognizes an interrupt by scanning the input byte 0. All modules (max. 8) used for interrupt generation must be accommodated in the same unit.
