Direct Current Sensing Relay
The CR5395 Series, Direct Current Sensing Relay provides a
CR5395 Series
OUTPUT OPTIONS
The Relay is available with three different output
configurations, electromechanical relay, op-
toisolated NPN transistor or ZeroCrossing op-
toisolated triac. Specify desired selection in part
number.
precision and cost effective method for monitoring Direct Cur-
rent. Magnetic Modulator Technology is utilized for the current
sensing to provide a stable and highly repeatable current trip.
The current-carrying wire is routed through the opening extend-
ing through the top of the case. When current reaches the level
set by the trip point adjustment, the relay trips and starts the ad-
justable timer. After the timer cycles the electromechanical relay
energizes.
