Schedule
 
EQUIPMENT:
Equipment and systems covered by this certificate are as follows:
 

TVOC is a wall mounted total volatile organic compound monitor and is designed to monitor the surrounding atmosphere for the presence of volatile organic compounds and provide both a local display of the concentration, and a corresponding 4-20mA signal for remote use.

It comprises electronic circuits and connectors on a PCB contained within an enclosure providing a degree of protection of at least IP20, together with a sensor mounted in a housing which protrudes from the bottom of the main enclosure.  The sensor may be marked with Certificate numbers IECEx CSA 06.0006X or IECEx CSA 06.0005X.

Input Parameters:

For Connector J1 (Power Supply):
Ui = 18V, Ii = 800mA, Pi = 1.2W, Li = 0 and Ci = 0

For Connector J2 (4-20mA Output):
Ui = 30V, Ii = 200mA, Pi = 1.2W, Li = 0 and Ci =0.

 
CONDITIONS OF CERTIFICATION: NO
