An Input/Output (IO) Expansion Board is a major component in modern access control systems. It acts as an interface between the access control panel and additional hardware devices, expanding the capabilities of the system to handle more devices, inputs, and outputs. This enables the access control system to scale according to the unique security requirements of the organisation such as managing multiple doors, sensors, alarms, or auxiliary devices such as turnstiles, gates, or locks.
The IO Expansion Board can be used with various devices such as Readers, Door locks, Sensors, Exit buttons and Push-to-Exit Switches, and Alarms/Notification Systems. Level up your security infrastructure with a wide array of IO Expansion Boards from Armatura, offered by ScreenCheck.
