EVS XS - Specifications

Opto isolated Inputs (GP In 1, 2, 3, 4)
Pin-Out
Specifications
• The input consists in an opto diode (VF @ 1.1 Volt) in series with a 470 ohm resistor.
• Typical switching point @ 1.4 mA, for secure operation:
◦ i=0 to 0.5 mA -> opto OFF
◦ i=2.5 to 30 mA -> opto ON
◦ imax= 30 mA
• Direct connection to a TTL/CMOS signal possible (Pin opto - to GND and pin opto + to
the TTL/CMOS signal).
Typical switching point @ 1.6 Volts, for secure operation:
◦ Vin< 0.8 Volts -> opto OFF
◦ Vin> 2.2 Volts @ 2 mA -> opto ON
◦ Vin max (without external resistor) = 15 Volts
