GAD 1501
Mode of Operation
8-channel receiver with 8 PNP
transistor outputs with open
collector.
Each output may be coded
individually by means of the
code programmer GAP 1605.
For details, please refer to the
respective data sheet.
The outputs are normally off.
Output 1 (pin 4) turns on when a
transmitter coded to the channel
for output 1 is activated.
Output 2 (pin 1) turns on when
the channel allocated to out-
put 2 is activated.
The outputs do not change
their status before having re-
ceived an activated/non-ac-
tivated channel for two con-
secutive pulse trains.
The default setting of the
module is such that upon loss
of Dupline
carrier all outputs
turn off.
Notes:
- The length of the DC sup-
ply-bus must not exceed 3
m in order to avoid distur-
bances unbalancing the
Dupline
.
- The common (pin 3) must
never be connected to pro-
tective ground or earth.
