The CMC series standalone accessory card provides an adjustable current limit alarm for any dc motor controller, preventing false alarms from predictable increases in current draw. Compatible with any dc motor controller, the card is wired in series with a dc motor using a jumper to set a base current limit trip point. An onboard OFFSET trim pot can finely adjust the trip point, while a TIME DELAY trim pot establishes how long the motor’s amperage draw must exceed the trip point before determining that a fault has occurred.
