A/CR-DC-5A Command Relay
Brand: Automation Components IncThe 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 will allow you to use the A/CR Series with any ACI current sensor or switch that incorporates the 35 mm 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.
An added benefit of the A/CR Series command relays separate from the current sensor or switch is that it allows you to mix and match any command relay model with any current sensor or switch model reducing the number of SKU’s needed.
All of the command relays can also be used in panel mount applications in place of a typical general purpose relay, since they have been tested to meet the UL 508 Industrial Equipment requirements.
Please contact ACI for more information regarding the Command Relays or to discuss your application in further detail.
