Quick Start Guide
Introduction
The SDC-620 is a multiple door controller that can control up to 8 doors. It has two relay outputs
and four inputs.
Up to 16 SDC controllers can be linked using a protected RS-485 network. The PC can connect to
it using either RS-232 or the built-in Ethernet connector or through the RS-485 network from
another controller.
It has a reader RS-485 network that can also connect up to sixteen slave devices including remote
I/O units.
Two Wiegand compatible devices can also be attached directly onto the controller.
The unit comes with a 12Vdc 5A power supply and a battery backup of 7Ah and is mounted in a
lockable case.

The outputs can provide 12Vdc power, or simply act as a potential free contact, allowing external DC or AC power to be switched through the relay. The configuration of this output mode can be accomplished using the jumpers J11 to J15. Possible output modes are listed below.
