5.1.9. Arc option card
Binary input
- operationg voltage +48 Vdc (optically isolated input)
Binary output
- Output voltage level +48 Vdc (transistor controlled output)
Max three binary inputs can be connected to one
uotput. More inputs can be connected if an
external amplifier is used.
Arc sensor inputs
- Number of inputs
- Operating voltage level
2
12 Vdc (optically isolated inputs)
Arc sensor draws > 11.9 mA current from the 12
Vdc line, when arc has been detected. Sensor and
sensor wiring is OK, when current is 1.3 mA..31
mA, otherwise sensor line is broken or short-
circuited.
