CSDECM-ADJ2 Johnson Controls Current Switch

Overview

The Johnson Controls CSDECM-ADJ2 is an adjustable current switch designed for reliable Go/No-Go run detection on Electronically Commutated Motors (ECMs). It features an adjustable turn-on setpoint to filter out the small amount of standby current drawn by idle ECMs, preventing false operational readings in building automation systems.

Features

• Adjustable turn-on setpoint via an easily scaled dial to ignore standby current
• Induced sensor power eliminates the need for an external power supply
• Includes an integrated command relay to save installation space and time
• Provides reliable loss of load and status detection for fractional horsepower motors

Specifications

• Amperage Range: Adjustable from 0.25 A to 3 A dial setting; 200 A maximum operational current
• Relay Contact Rating: Normally Closed (N.C.), 10 A at 125 VAC
• Actuation Coil: 24 VAC/VDC nominal
• Temperature Rating: 5°F to 140°F (-15°C to 60°C)
• Frequency Range: 50/60 Hz

Applications

• Go/No-Go run detection on Electronically Commutated Motors (ECMs)
• Fan and pump status monitoring in HVAC systems
• Commercial building automation and power management integration
