SDC-520 Ethernet controller
|
This is an intelligent Ethernet (TCP/IP) system controller with two relay outputs (potential free contact/powered output) and four programmable digital inputs capable of controlling two full normal doors, a bi-directional turnstile or a booth/mantrap onboard.
With the addition of Remote IO boards this can be expanded to 8 doors per controller.
It has two Wiegand interface connections on board and can handle up to 16 devices on its robust isolated multi-drop RS-485 reader/device network.
Remote I/O units can be connected either to control more doors (to a maximum of eight doors per controller) or simply for extra I/O points for controlling other devices.
It can be connected to other controllers using a robust multidrop RS-485 network which has isolation that protects the controllers on the network from electrical spikes of up to 2.4kV.
The unit comes with a 15Vdc 2.6A power supply with a battery backup of 7Ah and is mounted in a secure enclosure with a lockable door and mounting key holes on the outer edges.
