FACILITY AND METHOD FOR THE AUTOMATIC RECOGNITION AND DIFFERENTIATION OF SINGLE-CHANNEL OR DUAL-CHANNEL ELECTRONIC SENSORS CONNECTED TO A DUAL-CHANNEL SAFETY COMBINATION

摘要

electronic sensors (6,12) or the emergency stop button (22) in the form of emergency stop devices Equipment for the automatic recognition and distinction of the single channel or the dual-channel electronic sensor (12,6) connected to two pairs of connection lines (2, 3) a dual-channel safety combination (5) with about 4 ( 1) is described, the double channel of the first connecting conductor pair (2) is provided and a first connection line pair for the single-channel operation (2) and a second connecting line pair (3) of the safety combination (5) It provided for the operation and the equipment is connected to at least double ohm resistors arranged in the first connecting line (9) (13), and both connecting conductor pairs (2, 3) of the second connecting line pair (3) while through the channel electronic sensor (6) the current flows, the voltage drop across the ohm resistor 13 is switched to transistor 18, the output signal indicating the connection of the dual-channel electronic sensor (6) is a transistor (18) a collector (19) or that have already been created in the emitter 14, the emitter 14 ohm resistor or by the connection and a base (16) to the first side 19 of the ohm resistor (13) by the collector (19) ( and a transistor connected to the second side 17 of 13). A dual-channel safety combination (5) at least a single-channel or dual-channel electronic sensors (12,6), a method for the automatic recognition and distinction of which is connected to are also described.
