| 2-CHANNEL DIGITAL INPUT MODULE NAMUR CAGE CLAMP CONNECTION |
| The digital input module receives control signals from NAMUR proximity sensors (acc. to DIN 19234 and DIN 50227) from the field side. The voltage supply of each channel of the sensors is delivered by a short circuit proof 8.2 V 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 level are electrically isolated. |
