Access controller PR311SE

The PR 311SE external access controller is a single-passage controller used as part of the RACS 4 access control system, which is designed for the most popular access control solutions. It can be used in both standalone and networked installations of up to 1,000 users. All PRxx1 series controllers are equipped with an RS485 communication interface, which can be used both for their programming and for communication in a network system. Access control system based on PRxx1 controllers can be managed locally via COM/USB serial ports or remotely via WAN/LAN computer network required CPR32-NET-BRD panel. The controller has a built-in EM 125 kHz standard card reader. The device is equipped with three programmable NO/NC input lines, two programmable transistor outputs and one relay output, the PR 311SE model has a built-in keypad. Combining the device with the CPR32-SE control panel enriches the controller with new functions. Can be installed directly on a 60mm electrical box.
