5.2 Power Distribution Board

The primary purpose of the Power Distribution board is to provide primary power (7.5 to 24V DC
@1Amp/Hr) and to distribute power out to various communication modules & gas measurement products.
The communication modules will likely be a CloudLink, RV50 or RV50X or RV55 cellular MODEM. The gas
measurement products will be the 350- series products (configured as either EC350 electronic volume
corrector or ER350 pressure recorder) or legacy products, such as; Mini-Max, Mini-AT, ERX, etc.
The secondary purpose of the PD board is to switch MODEM power On or Off, based on a time-schedule
or on-demard call-in activity.
