The DS1 Series Current Sensing Switches are designed to trip a solid state contact when there is DC current through the sensor window. The sensor can be used to interlock two operations for safety. When one load is energized, the contact will keep another from also energizing. The power supply voltage and the controlled circuit voltage can be derived from a single source or separate sources.

DS1 Series


The monitored circuit can be any DC voltage and any amount of current as long as the conductor will pass through the window. The monitored circuit is completely isolated from the control circuit. If there is 3/4 of one amp through the aperture, the output will change state.

Current Sensing Switch Applications

  • As a Safety Interlock, it is a non-intrusive method to keep personnel safe.
  • Alarm contact when a load is operating or when it is not energized.
  • Detect PV system leakage by monitoring the earth bond conductor.
  • Use the contact to turn on a lighting circuit when a load is energized.
  • Instant indication of equipment status.

Current Sensing Switch Features

  • Compact, One-piece Design - Fits in easily amongst motor starters and power supplies in crowded control cabinets.
  • Input Isolation - Safer than shunt/relay combinations.
  • Unique Power Supply Connection - Sensor power and switched load share a common point making installation easy.
  • Built-in Mounting Feet - Simple, two-screw installation allows for secure mounting.

SymCom Monitor

SymCom's Model 601-575 is a fully programmable electronic voltage monitor designed to monitor three-phase voltage systems. When a harmful condition is detected, the MotorSaver's output relay is deactivated after the specified trip delay. The output relay reactivates after power line conditions return to an acceptable level for the programmed amount of restart delay time (RD2). The Model 601-575 can be used as a
