A547 Interface Module","description":"\u003cdiv\u003e\u003cp\u003eThe A547 Conductivity Interface from Campbell Scientific is a dedicated interface that lets a CS547A water conductivity probe be measured by Campbell Scientific data loggers. Inside, blocking capacitors and bridge completion resistors required for the conductivity measurement are housed in a metal case, and screw terminals provide connections to the data logger and to the probe or a multiplexer. One A547 is required for each CS547A when used directly with the logger; multiple CS547A probes can be used with an AM16\/32B multiplexer and a single A547. The unit ships with a six-conductor, three-foot cable for logger connection, while the A547-to-sensor connection uses direct terminal strips for single-sensor setups or a shielded 4-conductor cable to the COM terminals of a multiplexer. For CS547A measurement, the A547 requires two excitation channels and provides a differential input for conductivity and a single-ended input for temperature. Compatibility includes AM16\/32-series multiplexers and most Campbell Scientific data loggers when used with the A547. The case has mounting flanges for attachment to Campbell Scientific enclosures’ 1\"‑on‑center hole grid.
