Overview This chapter duplicates and consolidates information provided
elsewhere in this manual as a convenience to the reader.
Analog
Sensors
The SOLAIR can be fitted with up to four 4-20mA Analog sensors.
The Sensors are connected to the instrument using RJ-12 cables. The
connector pinout is shown in Table 4-1.
Note:
Changes to the
analog configuration will
change historical
environmental values in
the data buffer.
Each port can be used for one dual-channel or two single-channel 4-
20mA sensors (when wired correctly), two devices total per port. When
each port is connected to two single-channel analog sensors, a total of
four analog sensors may be connected to the SOLAIR. Otherwise, only
one single-channel or one dual-channel device may be used at a time on
each port. Please contact Lighthouse for additional information about
converters and wiring.
