Signal Conditioners

Our Bulletin 931N Nano and 931S Smart signal conditioners provide a full range of options to isolate, convert, split, linearize, and amplify a broad range of signal types. These products help protect your expensive control system from transients and noise while eliminating ground loop/noise-induced errors in process measurements through galvanic isolation. There are products with dual channels, input and output loop powered options. Products in these families offer excellent performance in terms of galvanic isolation, accuracy, response time, and power dissipation.

DIP Switch Configuration Tool — Several products in the 931 Nano and 931 Smart product families use DIP switch for configuration to meet customers’ signal requirements. To make dip switch identification easier, a simple configurator has been developed. In this program you can choose the product and enter your input and output signal requirements, the tool will show which DIP switches need to be turned ON. This eliminates the need to have datasheets or instruction sheets for identifying the right settings.
