Description

The NAMUR proximity sensor is widely used in industrial control when a special requirement on maximum energy is to be fulfilled by the sensor. This in turn dictates special requirements on the PLC digital input designed to interface with such sensor with regard to accuracy, and reliability. This reference design is a full front-end of a digital input compatible with NAMUR sensors. The design demonstrates achieving reliability through redundancy, fault protection, and extensive diagnostic features in a compact footprint.

Features
  • 1.6-mA threshold, 0.4-mA hysteresis
  • 0.2-mA open circuit, 6-mA short-circuit threshold
  • 8.2-V open-circuit voltage, 8.2-mA short-circuit current
  • Extensive diagnostics
  • Fault protection
  • Power and data isolation
  • Redundant components for higher reliability
