PIKE The inputs can be connected directly to +5 V. If a higher voltage is used, an external resistor must be placed in series. Use at +12 V a 820 Ω resistor and at +24 V a 2.2 kΩ resistor.

Caution PIKE

Voltages above +45 V may damage the optical coupler.

STINGRAY The inputs can be connected directly to +3 V ... + 30 V. (STINGRAY)

Caution STINGRAY

Voltages above +30 V may damage the optical coupler.
