AMP B Connector — Control
The console’s Tally 2 and Tally 3 control ports are on the SCD-5
AMP B connector. These are simple relay closures that activate whenever
programmed input modules are turned ON (see page 2-4). The ports can
be used to control externally powered tally lights that requires a continuous
closure to function.
Pin 11 – Tally 2 Relay COM
Pin 12 – Tally 2 Relay N.O.
Pin 8 – Tally 3 Relay COM
Pin 9 – Tally 3 Relay N.O.
Maximum current through
the tally relay closures is
2 amps @30VDC.
