CSD-CF0A0-1 Johnson Controls Current Switch

Overview

The Johnson Controls CSD-CF0A0-1 is a self-powered, split-core digital output current switch designed for non-intrusive monitoring of electrical current flowing through a cable or wire. It provides a cost-effective, reliable method for proof-of-operation monitoring, detecting very small current loads on commercial HVAC and building automation components.

Features

• Split-core design allows quick clamp-on installation without disconnecting wires
• Completely self-powered by drawing current induced from the monitored line
• 100% solid-state output with no moving parts ensuring high reliability
• Polarity-insensitive output simplifies wiring
• Snap-in mounting bracket fits neatly into tight mechanical enclosures

Specifications

• Amperage Range: 0.15 to 200 A AC
• Switch Setpoint: Fixed at 0.15 A
• Sensing Mode: Under-current sensing
• Status Output: Switch Normally Open (N.O.)
• Switch Load Capacity: 1 A at 30 VAC/42 VDC maximum
• Isolation Voltage: 600 VAC rms
• Temperature Range: 5°F to 140°F (-15°C to 60°C)
• Humidity Range: 0–95% non-condensing

Applications

• Fan and pump verification in air handling units and hydronic systems
• Motor run verification and load monitoring
• Building automation system (BAS) integration
• HVAC equipment fault detection and status alarming
