PULSE ISOLATOR

(built-in excitation)

Functions & Features

• Galvanically isolating pulse rate signals

• Input frequency = output frequency

• Various outputs (relay, open collector and voltage pulses)

• Excitation

• Isolation up to 2000 V AC

• High-density mounting

Typical Applications

• Isolating field pulse signals in order to reduce noises

• Changing e.g. dry contact signal to e.g. 5 V signals
