Πώς να μετρήσει το κανονικά άνοιγμα και κανονικά κλειστό σημεία του φωτοηλεκτρικό διακόπτης με α πολύμετρο
Διακρίνετε αν το φωτοηλεκτρικός διακόπτης είναι κανονικά ανοιχτό ή κανονικά κλειστό: 1. The single contact can be distincted from the model parameters; 2. Many products provide two sets of normally open and normally closed contacts at the same time, you can see the logo on the switch; 3. You can use a multimeter take measurements
Is the εγγύτητα διακόπτης κανονικά κλειστό ή κανονικά άνοιγμα?
1 . Three-wire DC24V επαγωγικό PNP type: brown connects to plus 24V, blue connects to 0V.
The black is connected to the red test lead of the DC voltage range of the digital multimeter, and the black test lead is connected to 0V.
At this time, the multimeter is normally closed with 24V voltage, and normally open without 24V voltage.
2 . Three-wire DC24V επαγωγικό NPN type: brown connects to plus 24V, blue connects to 0V.
Black Connect to the black test lead of the DC voltage range of the digital multimeter, and the red test lead to plus 24V.
At this time, the multimeter is normally closed when there is 24V voltage, and it is normally open when there is no 24V voltage.
