SPECIFICATION
Model
TDO16AIN
Power supply inputs
Has four separate connectors (FS1, FS2, FS3
and FS4) for dc power supplies. The four
positive supplies feed individual sections of
the digital outputs via common buses. The
buses are linked together. For lightly loaded
applications (e.g. 6A) all the required power
can be supplied via one connector. For highly
loaded applications (e.g. 16A) use multiple
power connectors.

Fuse blown indication
Local: Fuse blown LED (one per card)
Remote: Fuse blown alarm output (PL1) – can
be connected to Fuse blown LED on Power
Distribution Panel (PDD24).
Safety ground terminal TS1
M3 threaded bush provision for a ring terminal.
Allows the common 0V supply bus to be
grounded via a 10k ohm resistor. Prevents the
channels from floating if the card is
disconnected from the chassis.
Instrument 0V terminal TS2
M3 threaded bush provision for a ring terminal.
Allows the field 0V to be commoned for
transient suppression protection.
