The KTL-250 is an anemometer monitoring and alarming card. It allows the wind speed and direction to be measured with a Davis Instruments 7911 (included) Anemometer, without the need for the entire weather station.
Monitoring of the wind speed and direction can be done via the analog retransmission channels with 0-5V, 1-5V, 0-20mA or 4-20mA outputs. As well as monitoring the speed and direction, 2 alarm relays can be programmed to activate at a certain speed or wind direction range, or combination of the two. Wind speed and direction can also be monitored using the Modbus protocol with either USB or 2-wire RS-485 connection. All settings are set using the Modbus protocol and the provided software.
This model replaces the KTA-250.
