Occasionally, a customer may need to connect an “IX” version
of the sensor to a datalogger that has voltage excitation only
(e.g., CR10(X), CR800, CR1000). The customer can do this by
using a 4WPB1K terminal input module (refer to the 4WPB1K
manual for more information). NOTE
4.2 43502 Aspirated Radiation Shield Wiring
The shield includes a 115 Vac/12 Vdc transformer. In most applications AC
power is run to the tower or tripod and terminated in a junction box that is large
enough to house the transformer(s) as shown in FIGURE 4-2.
