Series 239 Analog Meter Relay

Series 239 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.

Meter Relay Types

  • 239-300A: One Relay, Two Set Points
    • Low Relay de-energized below Low (Left) Setpoint.
    • Midband maintains previous state until other setpoint is crossed.
    • Low Relays energized above High (Right) Setpoint.
  • 239-301A: One, Relay and Setpoint
    • High Relay de-energized below High Setpoint.
    • High Relay energized above High Setpoint.
  • 239-302A: Two Relays, Two Setpoints
    • Both Relays, Mid band de-energized
    • Low Relay energized below setpoint
