The Command Relay Series brings control (start/stop) functionality to your load trending and fan/pump/motor status monitoring and control applications. Each unit has a Form 1C – SPDT relay which provides both a Normally-Open “N/O” and a Normally-Closed “N/C” contact in a single device. The patented 35mm Din-Rail mounting flange allows you to use the NSA-A/CR Series with any current sensor or switch that incorporates the 35mm din rail mounting flange. The stacking feature allows you to reduce the required panel space, since up to two devices may be stacked together during installation and saves cost since two devices can be installed as a single component.
