Johnson Controls CSDSC-S75050L Current Sensing Relay Self-Powered SPST-NO 1.00A 30V

The Johnson Controls CSDSC-S75050L is a self-powered, self-calibrating solid-state current sensing relay designed for HVAC and industrial control applications. This intelligent device monitors current flow in electrical circuits and provides switching control without requiring external power supplies.

Key Features:

• Self-powered operation eliminates need for external control voltage
• Self-calibrating solid-state technology ensures accurate current detection
• Rated for 1.00A switching capacity at 30V
• SPST-NO (Single Pole Single Throw - Normally Open) contact configuration
• Surface mounting design for easy installation
• Solid-state construction provides reliable, long-lasting performance
• Ideal for monitoring pumps, fans, compressors, and other motor-driven equipment

This current sensing switch is commonly used in building automation systems to verify equipment operation, detect motor failures, and provide status feedback to control panels. The self-powered design harvests energy from the monitored circuit, making installation simpler and more cost-effective.
