With the Frequency Channel Expander, you can now add 6 frequency channels (pulse counters) to the 10 frequency channels already available on your Orbit 360 Premium data logger.
Accurately estimating the energy production during the development of a wind farm project requires very high assurance of the wind speed. To achieve this assurance, many wind farm developers are using taller and taller met masts for wind resource assessment and many are doubling up on the number of cup anemometers installed on each height (level) for redundancy and wakes.
The Orbit 360 Premium data logger by default include 10 physical frequency channels (pulse counters) that are used to read the output from e.g. a Thies First Class Advanced II cup anemometer. Apart from the physical frequency channels (pulse counters), the Orbit 360 Premium feature 6 channels dedicated to read the output from digital sensors, such as the Thies First Class Advanced X cup anemometer.
The Frequency Channel Expander is an external add-on module for the Orbit 360 Premium. It adds 6 frequency channels (pulse counters) to the data logger, enabling our users to connect a total of 16 cup anemometers with frequency output. It is a convenient and cost-effective solution to add both flexibility and reassurance to wind measurement campaigns where many traditional sensors are used.
Key features
- Conveniently adds 6 more frequency channels to the Orbit 360 Premium
- Single RS-485 communication interface with the Orbit 360 Premium
- All 6 channels feature same high precision as the Orbit 360 Premium
- Excellent noise and interface protection
- Each of the six channels can be configured individually
- IEC-61400.12.1 approved sampling rate of 1Hz
- Designed for use with Industry Standard DIN Rail Mounting
The channels on the Frequency Channel Expander module have the same features as the existing 10 frequency channels on the Orbit 360 Premium and are all fully compatible with the entire list of sensors already compatible with the default frequency channels on the Orbit 360 Premium. This means that you can connect any sensor whose output consists of pulses with a voltage level of between 0 and 5 volts. Typical examples of these type of sensors include cup anemometers such as Thies First Class Advanced, WindSensor or Vector; but also, K611PB (barometer) and Geovanes (True North orientation). Refer to the Orbit 360 User Guide for extended technical specifications.
Note: The Frequency Channel Expander is secured to the DIN rail in the cabinet and connected to the Orbit 360 Premium data logger via the RS-485 port.
