1 BIT LINE WEATHER INSTRUMENTS Interface BL232 with RS232/422/485 MODBUS and 0-10V outputs Qick and easy setup For domotic and building automation Wide Range power supply For solar and wind farm BIT LINE si riserva il diritto di apportare modifiche a modelli e specifiche senza preavviso DIN rail included OUT RS232/422/485/ and analog 0-10V Compatible with Davis Instruments HOW IT WORKS Interface BL232 Interface BL232 with analog interface The BL232 interface is the better product and the best value to manage a complete weather station with ASCII output RS232, RS422, RS485, Modbus, in addition to the optional analog outputs 0-10V output for each sensor if required. This interface is compatible with the set of external sensors Art 6322C or 6327C and converts it to a digital or analog outputs with a simple protocol, functional and compatible with the best data acquisition systems, home automation systems, PLC / TNC and more. Two more input channels for PT100 to manage a second temperature, which can represent the temperature of the PV module, road, sea or any other element, and one 4-20mA input channel, such as a professional first class ISO 9060 pyranometer, a visibility meter or a water level sensor for example. The board directly feeds the sensor assembly, with a single 11 4-wire 30 mt 24 AWG cable and also has an output to connect an optional local LCD display with datalogger. (Please note, the two additional inputs PT100 and 4-20mA are not stored in the datalogger) All data are available in clear ASCII 9600 bps RS232/485 every 60 seconds, and include: temperature, humidity, wind speed, wind direction, solar radiation, UV radiation, PT100 temperature, rainfall, barometric pressure, 4-20mA input, voltage and power voltage. The value of the rain is updated every minute or depending on the version of the firmware, or alternatively you can connect directly to the reed switch of the rain gauge for 0.2 mm of rainfall pulse. The anemometer has a 12 Mt of cable (extendable) for a better installation of the wind sensor.
