Description
The ZKTeco C3-400 Plus network controller is designed for managing four passage points and combines everything needed to build a distributed access control system in a single device. The expanded input matrix allows connecting readers, reed switches, and additional sensors without using external modules. Support for RS485 and TCP/IP, standalone operation, and a large amount of memory make the controller a universal ACS core for facilities of any scale.
Advantages
- Four passage points in one device: reduction of infrastructure cost compared with several two-door controllers
- 12 inputs and 8 outputs: full control of readers, reed switches, locks, and auxiliary devices
- 12 V DC, 1.5 A power: a standard voltage compatible with most uninterruptible power supplies
- 30,000 cards / 100,000 events memory: storage of the full user database without dependence on a server
- RS485 and TCP/IP interfaces: flexibility in integration into an already existing infrastructure
- Support for turnstiles and gates: control of complex passage mechanisms directly
Applications
- Industrial enterprises: control of several entrance groups and production zones
- Administrative buildings: management of floor entrances and meeting blocks
- Sports complexes and stadiums: control of the flow of visitors through several turnstiles
- Logistics centers and warehouses: restriction of access to zones storing valuable cargo
Frequently asked questions
What is the fundamental difference between the C3-400 Plus and the C3-200 Plus?
The C3-400 Plus manages four doors instead of two and has an expanded input and output matrix, which makes it possible to cover twice as many passage points without additional equipment.
Does the controller support operation in standalone mode?
Yes, when the connection to the server is lost the controller continues operation based on the stored local database of cards and access rules.
Can additional readers be added beyond four?
To expand the system, additional controllers or expansion modules are used; SAT Solutions specialists will help select the optimal configuration.
