Teledyne gfc 7000ta Analog Output Current Loop Range, Analog Output Pin Assignments

Operating Instructions Model GFC7000TA Carbon Dioxide Analyzer

The following DC current output limits apply to the current loop modules:

Table 6-18: Analog Output Current Loop Range

RANGE	MINIMUM OUTPUT	MAXIMUM OUTPUT
0-20 mA	0 mA	20 mA

These are the physical limits of the current loop modules, typical applications use 2-20 or 4-20 mA for the lower and upper limits. Please specify desired range when ordering this option.

The default offset for all ranges is 0 mA.

Pin assignments for the output connector at the rear panel of the instrument are shown in Table 6-19.
