CSDSCM-S75005L Johnson Controls Current Switch

Overview

The Johnson Controls CSDSCM-S75005L is a self-calibrating, solid-core current switch designed to provide reliable proof-of-operation monitoring for electrical equipment in commercial and industrial HVAC systems. It automatically detects the presence or absence of current flow in motors, fans, pumps, compressors, and other electrical loads, sending a dependable status signal to building automation systems (BAS) without requiring manual setpoint adjustments.

Features

• Self-calibrating design for fast, tool-free commissioning that automatically learns the normal operating current.
• Solid-state construction with no moving parts or mechanical contacts to ensure premium reliability and resistance to wear and vibration.
• Monitored load-powered operation that functions cleanly without requiring an external power supply.
• Fixed mini-sized solid core design built to easily fit into tight electrical enclosures.
• Preset functionality that reduces installation time and eliminates the need for live-panel adjustments.
