Setting up the SDC 8200 system

Connecting external equipment to the SDC 8200 AO’s phoenix connector
The SDC 8200 AO is fitted with a voltage-free contact (phoenix connector)
which turns external equipment (e.g. a recording unit) on and off. When a
console is active, the contact is closed and when no console is active, the
contact is open.
The phoenix connector is numbered from left to right as shown in the
illustration on the left.
If you switch AC loads such as e.g. an electronic relay, the contacts 1 and 3
will be opened or short-circuited. Therefore, make sure that the following
limitations are not exceeded!

If you connect DC sources such as e.g. a relay coil, make sure that the
following limitations are not exceeded!
y
Maximum load current (alternating) = 1.8 A
