Measurand is pleased to present SAA232 and SAA232-5 Products.
The SAA232-5 interface unit is designed to get the most out of your investment in SAA instrumentation. Geotechnical instruments generally use only a few sensors. SAA often has hundreds of sensors in one instrument. The elevated power demand of SAA requires tight control to provide optimum accuracy. A high quality DCDC converter is used to boost and regulate the voltage supplied by 12V battery systems that can range from 10.5V up to 15V depending on battery condition to a constant 13.5V (16.5V boost for longer cables). The SAA232-5 automatically limits SAA power consumption by only applying power to the SAA when the COM port is active. The capability of adding longer cables to reach further from your logger is also achieved by the use of the SAA232-5.
To protect your investment the SAA232-5 employs galvanic isolation to break fault currents from entering the SAA cable due to ground potential differences, a resettable fuse to protect wiring, and surge protection via clamping devices to minimize the risk of damage by voltage transients associated with power surges and lightning induced transients. For the surge protection to be effective the SAA232-5 ground terminal must be connected to earth to form a complete circuit for the voltage clamping devices internal to the SAA232-5.
