Delivered without miniature WSB markers
The digital input module receives control signals from NAMUR proximity
switches (based on DIN EN 60947-5-6) in the field.
The voltage supply of each channel of the sensors is delivered by a short circuit
proof 8.2V voltage source. A short circuit or a line break is indicated in the
process image (1 bit) and via the red LED.
The green LED indicates the input status:
• Signal current (0) LED off
• Signal current (1) LED on
Field and system levels are electrically isolated.
