Overview
The A547 is an interface that allows your Campbell Scientific data logger to measure a CS547A water conductivity probe. The A547 Conductivity Interface contains the blocking capacitors and bridge completion resistors necessary for the conductivity measurement. One A547 is required for each CS547A when used directly with the data logger; multiple CS547A probes can be used with an AM16/32B multiplexer and one A547.

Detailed Description
The A547 interface consists of blocking capacitors and bridge completion resistors housed in a metal case. Screw terminals are provided for connecting the data logger, and a water conductivity probe or multiplexer.

Additional Compatibility Information
Data Logger Considerations
Measurement of the CS547(A) via the A547 requires two excitation channels, a differential input for the conductivity measurement, and a single-ended input for the temperature measurement.
Multiplexers
The A547 is compatible with AM16/32-series multiplexers. When a multiplexer is used, the sensors connect to the COM terminals of the multiplexer and the multiplexer connects to the sensor terminals of the A547.
Cabling
Data Logger-to-A547
A six-conductor cable, three feet in length, is provided with each A547 purchase for connecting it to the data logger.
A547-to-Sensor(s)
In single-sensor applications, the sensor leads connect directly to the A547's terminal strips. In applications with multiple sensors, most customers multiplex the sensors through a multiplexer. In this case, a shielded 4-conductor cable is used to connect the sensor terminals on the A547 with the COM terminals on the multiplexer.
Enclosures
The A547 requires a desiccated, non-condensing environment. The A547's case has mounting flanges for attachment to the 1"-on-center hole grid of Campbell Scientific enclosures. Grommets and screws are provided to attach the flanges to the backplate of our enclosures.
