and eight 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.
The unit comes with a 12Vdc 5A power supply and a battery backup of 7Ah and is mounted in a

    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.
