Black Box AlertWerks 4-20mAmp Converter - DIN Mountable, Screw Mount for Signaling System
AlertWerks Gateways and Sensors enable you to communicate with equipment to monitor environmental conditions. But did you know that you can integrate third-party 4-20 mA industrial sensors with your AlertWerks solution? The 4-20 mA Converter from Black Box makes this possible!
State-of-the-Art Solution
4-20 mA technology is used to communicate analog signals over long distances where electrical interference is a problem. The 4-20 mAmp signal converter integrates the AlertWerks Gateway with a 4-20 mAmp transmitter. Using 4-20 mAmp technology, it communicates analog signals over long distances where electrical interference is a problem. This solution is often used in the process control industry to collect analog values from a wide array of remote sensors.Reduce Noise and Drive Longer Distances with Current Signals vs. Voltage Signals
Current signals are much less susceptible to noise than voltage signals. A voltage signal can be converted to current and then broadcast over a long distance before it is converted back to voltage and read by the gateway.Best-Practice Transmitters
4-20 mAmp transmitters are common in the industry for use with high-quality sensors. With the 4-20 mAmp converter, these sensors can now be integrated into the AlertWerks Gateway, to enhance their value by adding graphing, web interface, email interface, thresholds, and limits.Next Steps
Enjoy the benefits of using third-party sensors to add value to your AlertWerks solution. Use the 4-20 mA Converter from Black Box with high-quality, third-party sensors in industrial settings.Save Power, Too!
