Description of Equipment:
The PMA.Evolution is designed for the measurement of weight in the hazardous location. The 
PMA.Evolution contains the processing circuitry and has a touch enable LCD display with backlight facility. 
Power and data to the non-hazardous or unclassified location are provided via the YCO14-Z or YCO14-Y
Ex-Link Converter. All signal outputs to the YCO14-Z or YCO14-Y Ex-Link Converter are available in RS232 
communications. Both the PMA.Evolution and the YCO14-Z or YCO14-Y Ex-Link Converter are housed 
within non-metallic enclosures. A dedicated potential equalization connection is provided on both the 
PMA.Evolution and the YCO14-Z or YCO14-Y Ex-Link Converter. Power and data connections between the 
YCO14-Z and YCO14-Y Ex-Link Converter and the PMA.Evolution are made via a multi-conductor CAT6
