8.2) STANDARD 

DIGITAL 

OUTPUTS 

The schematic of the 2 standard digital outputs PHOTOMOS of EMA11 is represented on the following 
figure: 

 
Power supply from 12 to 230 Vac-dc, load must not exceed 150mA, 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 (consult the chapter 
11.8). 
The signs + and - on outputs in the picture have electric meaningless. 
 

If long distances must be covered, the wires connected to the EMA11 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.
