SEW 31C450-503-4-00 Frequency driven.Classification of gate controllers:
1. According to the communication mode of the door controller and the management computer, it is divided into RS485 networked door controller, TCP/IP network door controller, and non-networked door controller.
(1) No network door controller, is a machine to manage a door, can not be controlled by computer software, can not see the record, directly through the controller for control. It is characterized by low price, simple installation and maintenance, can not check records, not suitable for more than 50 people or people often flow (refers to people often enter and leave), and not suitable for the number of doors more than 5 projects.
(2) 485 network door controller, is can communicate with the computer access control type, directly use software for management, including card and event control. So you have easy management, centralized control, you can view records, you can analyze records for other purposes. Features are relatively high price, installation and maintenance, but simple training, attendance and other value-added services. It is suitable for the project with many people, large mobility and many doors.
(3) TCP/IP network door controller, also known as Ethernet network access control, is also an access control system that can be networked, but the computer and the controller are networked through the network line. In addition to all the advantages of 485 access control network, it also has faster speed, simpler installation, a larger number of networking, and can be cross-regional or cross-city networking. But there is a high cost of equipment, the need for computer network knowledge. Suitable for installation in large projects, large number of people, speed requirements, cross-regional projects.
