The main purpose of digital input modules, which come in several varieties, is to receive binary control signals from proximity switches, transmitters, sensors, and switches.
They will meet your need for well-coordinated project planning with reserve potential because of its adaptable design.
All modules completely adhere to IEC 61131-2 and come with four, eight, or sixteen inputs.
There are two types of digital input modules: P-switching and N-switching.
According to the specification, the digital inputs are for Type 1 and Type 3 sensors.
They are employed in a wide range of applications and have a maximum input frequency of 1 kHz.
The variant for PLC interface units allows for quick connecting to the well-known interface sub-assemblies using system cables.
This guarantees quick integration into your entire system.
Binary signals can be captured, and a timestamp with a resolution of 1 μs can be provided by two modules with a timestamp function.
