The 252-PBAU dc transducer protector relay offers adjustable trip point (set point) and time delay settings. The time delay setting adjustment range is typically 0 to 10 seconds, although longer delays are available. When the monitored signal moves outside of the set point, the time delay is activated, and a trip occurs. The time delay prevents nuisance tripping. The products also feature an internal differential (hysteresis) setting of 1% to reduce nuisance tripping if the measured signal is noisy or unstable. These units require an auxiliary power supply.
