AS1 DODC SERIES

Current Sensing Switches

AS1 DODC Series current sensing switches with dual output are ideal for applications where users want to monitor multiple loads simultaneously and alarm when cumulative current draws reach or exceed desired setpoints. Combining the set-point, LED indication and output functions of multiple sensors into one space-saving package, the AS1 DODC Series current sensing switches allow OEMs to tailor individual trip points to specific processes and trigger independent contacts. The AS1 DODC current sensing switch may serve as an effective over/undercurrent monitor by energizing alarm contacts whenever sensed current falls outside the low and high band setpoints.

Fixed Start-up Delay and Adjustable Trip Timer
  • Delay of 2 seconds reduces nuisance trips on inrush
Choice of Dual Independent N.O. Relay Outputs
  • Contact rating of 1A @ 30VDC provides adequate switching capacity for status or indication in most motor control systems without shared common
Improved Ease of Installation and Use
  • Self-powered design eliminates power supply wiring
  • Multiple status LEDs give quick visual indication of sensor operation
  • Models available for low (0.75-20A) and mid-range (20-50A) applications
Industrial Grade Performance
  • +/- 2% accuracy on set-point, minimal hysteresis and fast response time deliver performance
