Connecting magnetic lock to a controller
Description:
How to connect magnetic lock to a controller?
Solution:
- Supply Plus of the magnetic lock has to be connected to +12V power supply,
- Supply minus of the magnetic lock has to be connected to NC terminal built in output relay in controller,
- Make connection between COM terminal of the built in terminal and negative GND of the power supply.
Magnetic lock which opens door has to be powered by separate pair of wires connected directly to power supply. Semiconductor LED diode (for example 1N400x series) has to be connected to the magnetic lock. It is recommended to connect the diode most closely to the magnetic lock in order to avoid propagation of electric distortions.
