CSD-SA1E1-1 Johnson Controls Current Switch

Overview

The Johnson Controls CSD-SA1E1-1 is a solid-core, adjustable current switch with an integrated command relay designed to non-intrusively detect current flowing through a cable or wire. It provides a cost-effective solution for monitoring on/off status or proof of operation while facilitating the starting and stopping of the monitored motor.

Features

• Dual function that monitors current and controls motor start/stop
• 100% solid-state status output with no moving parts to fail
• Self-powered sensing circuit induced directly from the monitored line
• Polarity insensitive output for simplified wiring
• Snap-in mounting bracket and compact size for tight enclosures

Specifications

• Amperage Range: 1.00 to 135 A (Adjustable setpoint)
• Output Relay: SPST, Normally Open, 10 A at 260 VAC, 5 A at 30 VDC
• Actuation Coil: 20 to 30 VAC/VDC, 40 to 85 mA maximum
• Switch Load Capacity: 1 A at 30 VAC / 42 VDC maximum
• Operating Temperature: 5 to 140 degrees Fahrenheit (-15 to 60 degrees Celsius)
• Humidity Range: 0 to 95% RH, non-condensing
• Sensing Aperture: 0.71 inch (18 mm) diameter

Applications

• Motor run verification for fans, blowers, heating coils, and pumps
• Proof-of-flow status detection in commercial air handling systems
• Over and under current fault signaling
• Integration with building automation and energy management systems
