With a 4-20mA Expansion Card, the status of a BMS cannot only be monitored, but input information can be relayed and acted upon. Tank level and fuel pressure signals can be sent from an end user and through the 4-20mA Expansion Card, that information is received and the burner management system will respond accordingly. Our 4-20mA Expansion Card allows oilfield professionals to always know the status of their applications, whether in the field or in the office.
