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 an RS232 or 2-wire RS485 connection. All settings are set using the Modbus protocol and the provided software.
Features:
- Connects to Davis Instruments DS7911 Anemometer
- Monitor both the wind speed and direction
- Interface to PLC's using the Modbus protocol
- Communicate via RS232 or 2-wire RS485
- Interface to PLC's/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
- DIN Rail mounting available
