Description: The KTA-250 is an anemometer monitoring and alarming card. It allows the wind speed and direction to be measured with a Davis Instruments DS7911 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.
8 - 24 VDC Powered
Connects to Davis Instruments DS7911 Anemometer
Monitor both the wind speed and direction
Interface to PLCs using the Modbus protocol
Communicate via USB or 2-wire RS485
Interface to PLCs/Instruments or other controllers using 4-20mA or 0-5V signals
Generate relay alarms depending on the wind speed and direction
Alarms can be monitored by the on board relays or via the Modbus protocol
