ATC Diversified CDO-120-ALE-20 4.0 to 20 Amps DC Over Current Relay

ATC Diversified, CDO-120-ALE-20, 4.0 to 20 Amps DC Over Current Monitor/Relay

Features:

• DC over the current monitor
• Lock shaft adjustments for the Current trip point and On-delay time
• Automatic reset

Applications:

• Current demand level monitoring
• Conveyor or motor load jam detection
• Dull bit or blade detection
• Remote motor sensing
• Broken fan belt or chain detection
• Feed rate to keep two loads at their most efficient point

The CDO Series DC Over Current Monitor from the ATC Diversified Electronics division of Marsh Bellofram is used to detect both DC Over Current conditions which could have a potentially negative effect on the continuous operation of motors, pumps, or other critical industrial machinery. The internal relay energizes (pick-up) when the monitored current exceeds the preset trip point for longer than the adjustable time delay. The delay is incorporated to prevent nuisance tripping caused by inrush currents. The CDO has an automatic reset feature. The internal relay de-energizes (drop-out) when the current drops 5% below the preset trip for longer than 0.2 seconds.
