Reliable detection and processing of digital signals is essential in modern automation technology. Digital signals are transmitted via high level (logic 1) and low level (logic 0). Digital input modules with optocouplers are often used for reliable decoupling and signal transmission. The galvanic isolation ensures reliable interference immunity and protects sensitive electronics from voltage peaks or potential differences.

Typical digital signal sources include:

• Switches, limit switches, buttons
• pulse counters, rotary encoders
• Motion detectors, light barriers, proximity sensors
• Outputs from relays or MOSFETs
• Output signals from measuring devices and control systems

Our modules support use in digital control systems, signal processing units, Industry 4.0 systems and measurement and control technology.
