How to connect PLC to control access control system

Be sure to turn the power off before wiring, wiring under power may cause serious damage to the device. Below is a diagram of the ACM2110 interface.

Requirements for the power supply when connecting the power cable of ACM2110 controller, rated voltage AC/DC 24V±30%, rated current max 800mA.

The connection pins of ACM2110 controller and power supply are concentrated in TB1 module, the following is the schematic diagram of the connection between controller and power supply. The main power supply of the system can be powered by battery or AC mains only, or it can be converted to a low voltage DC supply using an AC power source. Secondary batteries and chargers, ups power supplies, and generators can be used as backup power. When the system only uses battery power supply, the battery capacity should ensure that the system is normally opened more than 10000 times. When the system uses a backup battery, the battery capacity should ensure that the system works continuously for not less than 48h, and during which the system is normally opened more than 50 times.
