Voltage Converter


SKU: SH-PRB-00-110 Category:


The 4-20 mAmp Voltage Converter is used to integrate the Base Units with a 4-20 mAmp transmitter. 4-20 mAmp Voltage Converter technology is used to communicate analog signals over long distances where electrical interference is a problem. This solution is often used in the process control industry to collect the analog values from a wide array of remote sensors. 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 Base Unit.

4-20 mAmp Voltage Converter transmitters are common in the industry for use with high quality sensors. With the 4-20 mAmp Voltage Converter these sensors can now be integrated into the Base Unit enhancing their value with the addition of graphing, web interface, email interface, thresholds, and limits.

It works with all SensorHawk Base Units and SecurityHawk Base Units and must be connected to a base unit in order to function properly.
