CURRENT SENSOR with RELAY OUTPUT, 10-20 AMPS
CS Current Sensor
Timing Mode | Delay After Sense
Category | Current Sensor
Series | CS
The CS is an over or under current sensing control. Toroidal sensing means no break in the power wiring.
The combination of the over current LED, current adjustment, and percentage trip adjustment provides easy and accurate setting.
CS can handle loads up to 20 amps with time delays up to 100 secs.
Sense Mode
When the sensed current increases above or falls below the set point, the time delay will start.
At the end of the delay, the output will be energized.
