Remote Sensor, Network I/O, Gas Connector Panel | Teledyne 3020T

Trace Oxygen Analyzer		Introduction 1

• Remote Sensor	Used for external sensor and
	thermocouple, if desired.

•Remote Span/Zero Digital inputs allow external control of analyzer calibration.

•Calibration Contact To notify external equipment that instrument is being calibrated and readings are not monitoring sample.

•Range ID Contacts Four separate, dedicated, range relay contacts. Low, Medium, High, Cal.

• Network I/O	Serial digital communications for local
	network access. For future expansion.
	Not implemented at this printing.

1.7.2 Gas Connector Panel

The gas connector panel, shown in Figure 1-3, contains the gas con- nections for external inlets and outlets. Those that are optional are shown shaded in the figure. The connectors are described briefly here and in detail in the Installation chapter of this manual.
