PULSE ISOLATOR
(isolated two outputs; 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

When combinations "a voltage pulse and an open collector" or "a relay contact and an open collecctor"
are chosen, be aware that the logic of the output 2 is inverted.
