Signal Interface

Our signal interface products provide signal conversion and electrical isolation between sensors and other field devices and a control circuit. Intrinsic safety modules add Zener diodes, which limit the amount of electrical energy on intrinsically safe circuits.

Bulletin 931 Signal Conditioners

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.

Intrinsic Safety Modules

Intrinsic Safety Modules

Our intrinsic safety modules connect intrinsically safe rated equipment, such as transmitters, solenoids, proximity sensors and encapsulated assemblies, with control systems. An intrinsic safety approach can be more cost-effective than other hazardous location protection/mitigation strategies in Class l, Division 1 (Zones 0 and 1) locations.
