Digital Command Terminals
Plate (O) discharges the floating
plate to zero volts.
Plate (+) precharges the floating
plate to +55 V.
Plate (-) precharges the floating
plate to -55V.
All the above digital command
inputs are at a 10 V DC High
Level. A minimum of 6 mA of
current sink capability is required
to pull the digital command inputs
to ground (0 V).
