Model GFC7000TA Carbon Dioxide Analyzer

3.5.4. Connecting the Status Outputs

If you wish utilize the analyzer’s status outputs to interface with a device that accepts logic-level digital inputs, such as programmable logic controllers (PLC’s) they are accessed via a 12-pin connector on the analyzer’s rear panel labeled STATUS.

STATUS

1 2 3 4 5 6 7 8 D

+

NOTE

Most PLC’s have internal provisions for limiting the current the input will draw. When connecting to a unit that does not have this feature, external resistors must be used to limit the current through the individual transistor outputs to ≤50mA (120 Ω for 5V supply).

The pin assignments for the status outputs can be found in the table below:
