  • Monitors and Controls Any Variable Which Can be Converted
  • Into an AC or DC Signal
  • Rugged Shock and Vibration Resistant Design
  • Indicator, Relays and Power Unit in One Housing
  • Control Function Continues if the Indicator Becomes Damaged
  • Stable Electronic Switching Circuit Does Not Use Lamps, Photocells, Inductors or Capacitors
  • Taut Band, Fluid Damped Indicator
  • Isolated Input Signal
  • LED Relay State Indicators
Series 239 and 007 meter relays combine a highly accurate indicator with High and Low set point relays. The relays can operate alarm and control devices when the monitored signal value moves outside the chosen set point limits shown by adjustable red index pointers. A single compact case houses the unit which requires only the input signal and power supply thus saving space and installation time.
