Daisy-chaining SDC 8000 AO analog output units

To daisy-chain SDC 8000 AO analog output units:

￿Connect the DIGITAL BUS OUT socket of the first SDC 8000 AO to the DIGITAL BUS IN socket of the second SDC 8000 AO, and so on.

Note!

You can connect up to four daisy-chained SDC 8000 AO analog output units to the central unit.

Connecting external equipment to the SDC 8000 AO’s phoenix connector

The SDC 8000 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!

Maximum load current (continuous) = 1 A

Maximum load voltage = 60 V

On-resistance = 0.5

If you connect DC sources such as e.g. a relay coil, make sure that the following limitations are not exceeded!

Maximum load current (continuous) = 1.8 A

Maximum load voltage = 60 V

On-resistance = 0.15
