Appendix F – Switched Power Control for Campbell Dataloggers
Campbell Scientific dataloggers include programmable power outputs, such as Switch 12 (SW12), which can
be used to control power to connected devices, such as the Lantronix SGX 5150.
(Figure 28)
SW12 provides a programmable output of 12 volts to the connected device and by doing so, the following can
be achieved:
• Power cycle the connected device, allowing a reconnection to the local Wi-Fi network.
• Reducing the power consumption of an entire unit by turning power on at specified times rather than
being continuously powered.
To use switch power control, the datalogger program must be updated and the device’s power inputs must be
rewired to connect to SW12 instead of the charge regulator.
Note
−
Devices that requires more than 1 amp of power cannot be powered through SW12. If a device
requires more than 1 amp of power, contact Canary Systems.
