CSDECM-ADJ4 Johnson Controls Current Switch

Overview

The Johnson Controls CSDECM-ADJ4 is a current switch device designed for monitoring Electronically Commutated Motors (ECMs) and other electrical loads. It features an adjustable trip setpoint range of 0.25 to 3 A and a Normally Closed (N.C.) status output with a 12 VDC coil configuration, providing reliable verification of equipment operation and preventing false readings from motor idle currents.

Features

• Mini-sized solid core design suitable for tight electrical enclosures
• Adjustable trip setpoint ranging from 0.25 A to 3 A
• Normally Closed (N.C.) status output configuration
• Induced power directly from the monitored conductor cable eliminating the need for an external power supply
• Polarity insensitive output for simplified wiring

Specifications

• Amperage Range: 0.25 to 3 A (Adjustable)
• Output Type: Normally Closed (N.C.)
• Relay Coil Voltage: 12 VDC
• Core Type: Solid Core
• Frequency Range: 50/60 Hz
• Temperature Range: 5 to 140°F (-15 to 60°C)
• Humidity Range: 0 to 95% noncondensing
• Isolation Voltage: 600 VAC rms

Applications

• Electronically Commutated Motor (ECM) status monitoring
• Commercial HVAC fan, pump, and compressor operational verification
• High-traffic building automation load status sensing
• Sub-fractional horsepower motor runtime tracking
