FUNCTION & FEATURES
• Galvanically isolating pulse rate signals from a rotary encoder
• Maximum input/output frequencies: 100 kHz
• Minimum input pulse width: 5 µsec. (dry contact, voltage/current pulse input)
• Monitor LED provided to check that input pulses are provided.
• Accepting a wide variety of input: 0.5 – 50 V at the input terminals
• Pulse logic can be converted.
• RS-422 line driver pulse input acceptable; converted into open collector or voltage pulse output.
• For one-shot output, a pulse rise or drop can be selected for synchronization.
• Output 1 is available with power photo MOSFET relay.
