Connecting the optional Ribbon Header Outputs (Model C1426)
The Omni8/16C may be fitted with an optional Ribbon Header Output Board. (The Model C1479 Omni16C
Remote Logic Unit is fitted with this board as standard.)
This board is equipped with two 20 way ribbon cable headers.
The first header provides 16 outputs used to drive a remote display. The output will be on when the
corresponding lamp is illuminated.
In panel mount Omni8/16C units with integral displays, the lamp repeat outputs on this board are in
parallel with internal lamps in the unit.
The second ribbon cable header provides 16 outputs as repeats of each alarm input in the unit. This
header may be used for connecting to other equipment such as OMNIFLEX’s OMNILOG sequence-of-event
recorders.
The output will be off when the corresponding input is the normal condition, and will be on when the input
is in the alarm condition. This is independent of whether the input is set to be normally open or normally
closed.
Each of these outputs is an open collector transistor output with the following electrical specification:
Collector Voltage
40Volts max.
Collector Current
100mA max.
CAUTION:
These outputs are not protected from short circuits, and exceeding the above ratings will damage the unit.
