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.

Product Comparison

931N Nano

Bulletin 931N Nano Signal Conditioners are extremely slim at 6.1mm width The Nano series has a power DIN rail option which reduces the need to wire every device for power supply.

For more information, see the Nano Series Product Overview in the Signal Conditioner Specifications Technical Data publication.

931S Smart

931S Smart Bulletin 931S Smart Signal Conditioners can handle complex signals including higher current, voltage, frequency, bridge circuits and HART. The current monitoring and measurement devices use hall- effect sensor technology via through hole in compact DIN mountable housing.

Additional Information

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.
