SDC-620: Wiegand Door Controller

This replacement for the SDC-520 controller incorporates a host of new design features and increased functionality. Most notable amongst these are the Micro SD for increased capacities, additional dedicated fire and tamper inputs, OLED control module for easy setup and setup and local diagnostics as well as a OSDP secure channel compatibility.

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 terminals on its robust isolated multi-drop RS-485 terminal 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 controller 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 5A 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.
