2LP227 is a high-performance single-chip intelligent seromechanical parking barrier with TTL input/output interface, 4 SMT (Surface Mount Device) and two LED display windows. It can provide various kinds of serial connections between computers and shared devices. The hardware of 2LP227 has a multi-functional operation mode, which can adapt to any complex application system.

2LP227 is widely used in access control system, parking system, queue management system, elevator control system, etc. The working principle of the 2LP227 is to receive and interpret the instructions (A1, A2,..etc.) from the host computer, and then to trigger All the relays in sequence. This includes controlling the sliding door, light, sound, direction of the appropriate direction indicator, voltage control, logic sychronization, etc.

2LP227 is an integrated device that can be used to control access systems, such as automatic door systems, elevator control systems, and so on. It has a reliable operation even under harsh environments. The operation mode is easy to set up, it is embedded with an EEPROM for saving standing commands, and it supports various serial control commands with 80 to 90 bytes. On the other hand, it also can be set up to work in a synchronized mode, so that multiple 2LP227 can be as a single system.

In addition to the above mentioned working principle, 2LP227 also has a variety of functional modes, such as input mode, output mode, counter mode and timer mode. In the input mode, 2LP227 can receive instructions from the host computer and control the relays accordingly. In output mode, 2LP227 monitors input points and transmits information to host computer. In counter mode, it can create a count initiation signal, set event count value, reset the counter, etc. Finally, in timer mode, the user can set on/off(or pulse) time, and stop or activate the counting time.

2LP227 is a versatile and powerful device that can be used in a variety of applications. With its integrated multiple functionalities, 2LP227 has been widely used in access control system, parking system, queue management system, elevator control system, etc. It is a reliable and cost-effective solution that can ensure the safe operation of any access control system.
