Our ON/OFF Module, used in combination with the Orbit data logger, is designed to control external power applications that may be required in certain wind or solar measurement campaigns. A good example where the ON/OFF module can be of great use is for switching a power supply system for sensor heating on and off.
The ON/OFF module allows users to control circuits by switching them on or off. The module works with the Orbit 360 Premium data logger and can be configured through Atlas. The circuits can be switched based on the values of any input channel, the UTC hour, or the user’s manual settings. This adds significant flexibility when dimensioning and setting up a heating system, for example, for ultrasonic sensors in cold climates. Please note that Atlas enables implementing “OR” functions, whereas the ON/OFF module allows to implement “AND” functions by wiring two or more relays in series.
An example of a typical setup using the 2-relay version of the ON/OFF module:
If you are planning to set up a heating system that will take into account both the outside temperature AND the humidity before activating the heating system, you may order the ON/OFF module with 2 relays. If you furthermore need to control another circuit, for example, for activating an obstruction light, you should use the version with 6 relays.
