CSDECM-ADJ0 Johnson Controls Current Switch

Overview

The Johnson Controls CSDECM-ADJ0 is an Electronically Commutated Motor (ECM) adjustable current switch designed to monitor and verify motor operation across a wide adjustable current range of 0.25 to 3 Amps. It provides a simple, reliable method to confirm motor run status and can be integrated into building automation systems for fault detection and diagnostics without requiring live calibration.

Features

• Adjustable current sensing range of 0.25–3A to accommodate a variety of ECM motor loads.
• Non-invasive current monitoring that eliminates the need for direct wiring into the load circuit.
• Low turn-on current capabilities that extend utility to sub-fractional HP motors.
• Split-core or solid-core design options that simplify installation without de-wiring existing systems.
• Polarity insensitive solid-state output for easier wiring and installation setup.

Specifications

• Current Range: 0.25 A to 3 A dial setting, 200 A maximum operational current.
• Sensor Output Rating: 1.0 A @ 30 VAC/VDC, solid-state FET (Normally Open).
• Frequency Range: 50/60 Hz.
• Temperature Range: 5°F to 140°F (-15°C to 60°C).
• Humidity Range: 0 to 95% non-condensing.
• Dimensions: 2.5 in. x 2.23 in. x 0.82 in.

Applications

• Verifying run status for ECM blower motors and fan motors in commercial HVAC systems.
• Pump and compressor operation monitoring within building automation panels.
• Remote equipment status verification and load loss detection in air handling units and ventilation systems.
