2 RELAY

re-transmit as a  0-20mA OR  4-20mA signal

This device is used to measure and display true RMS AC voltage signals.

ADDITIONAL FEATURES INCLUDE:

  • DISPLAY SCALE: adjust the display to match the input of a voltage transformer
  • START-UP DELAY: At START-UP delay relay remains energized for this pre-set time to allow input voltage to stabalize before monitoring starts.
  • REACTION DELAY: (TRIPP DELAY) Once energized, the relay will tolorate fault conditions for this pre-set time before it is de-energized. This allows for short term fault conditions.
  • RECOVERY DELAY: Whenever the relay is de-activated, it will not operate again until this time has lapsed
  • LATCH FACILITY: Once de-energised, the relay will not operate until the short across the latch pins is removed (even if the fault condition has been corrected)
  • Auxilliary supply voltage is isolated from the measured AC
  • keypad lock with code

Relay(s) remain energized while monitored voltage remains within pre-set upper & lower values.

Once tripped, the voltage must recover by the pre-set hysteresis voltage (difference between trip & recovery) before the relay operates again.

 

Display scale:                           Adjust the display to match the input of a voltage transformer.

Start-up delay:                          At start-up the relay remains energized for this pre-set time to allow the input voltage to stabilize before monitoring starts.

Reaction delay: (tripp delay)       Once energized, the relay will tolerate fault conditions for this pre-set time before the relay is de-energized. This allows for short term fault conditions.

Recovery delay:                        Whenever the relay is de-activated, it will not operate again until this time has lapsed.

Latch facility:                            Once de-energized, the relay will not operate until the short across the latch pins is removed. (even if the fault condition has been corrected).
