Comparator for analog sensors


Supports both voltage and current inputs.
Equipped with a 24 VDC sensor power supply.

  • Analog input from sensor convertible to four ON/OFF outputs
    Using a single analog sensor easily realizes a system setup of liquid level monitoring.
  • Supports both voltage and current types of analog input
    Analog output sensor of 4-20 mA, 0-5 V, or 0-10 V can be used.
  • Simple, button entry of settings
    Setting increments of 0.01 V or 0.01 mA are available.
  • Analog input averaging from 1 Hz to 200 Hz
    Averaging reduces input noise, stabilizes operation, and improves display intelligibility.
  • Adjustable hysteresis
    Hysteresis on each output is individually adjustable to avoid chattering around the threshold.
