EMA-D9 - USER MANUAL
-22-
7.3) STANDARD
DIGITAL
OUTPUTS
The schematic of the 2 standard digital outputs PHOTOMOS of EMA-D9 is represented on the
following figure:
Power supply from 12 a 260 Vac-dc, load must not exceed 100mA, typical resistor value of
PHOTOMOS outputs, closed contact, is 8
Ω
(R
ONmax
= 12
Ω
). Each output may be programmed by the
operator on min/max threshold, external band, always ON or/and pulse output.
The signs + and - on outputs in the picture have electric meaningless.
If long distances must be covered, the wires connected to the EMA-D9 needs to be wired in a
separate channel from the power supply cables, if an intersection occurs between the power supply
cable and the analog wires, please remember to cross the intersection at 90 degrees, in order to cut
the generated magnetic fields.
