| CDD Series Universal DC Current Monitoring Relay |
| Series Description: The CDD Series Universal DC Current Monitoring Relay from the ATC Diversified Electronics division of Marsh Bellofram is used to detect both DC under and over current conditions which could have a potentially negative effect on the continuous operation of motors, pumps or other critical industrial machinery. The series may be used as either a DC over current monitor or a DC under current monitor. The series features an adjustable delay-on-operate and adjustable delay-on-release time delay. When the current exceeds the preset current trip point for longer than the delay-on-operate time delay, the internal relay will energize (pick-up). When DC current drops below the preset current trip point for a longer duration than the delay-on-release time delay, the internal relay will de-energize (drop-out). When used as an over current monitor, the delay-on-operate time delay is used to override any inrush periods. When used as an undercurrent monitor, the delay-on-release timer is used to override a temporary under current condition. |
