2-channel digital input

2-channel digital input; NAMUR; Light greyThe digital input module receives control signals sent from NAMUR proximity switches in the field (according to DIN EN 60947-5-6). The voltage supply for each channel of the sensors is taken from a short-circuit protected 8.2 V power supply. A short circuit or line break is indicated in the process image (1 bit) and a red LED. Green LED indicates input status: Signal current (0) LED off Signal current (1) LED on Field and system levels are electrically isolated.
