EN.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.

931H High-Density Image

Bulletin 931H High-Density Series Signal Conditioners are 6mm wide, which saves panel space. These products provide isolation and conversion solutions for current, voltage, and temperature (thermocouples and RTDs) signals.

931S Standard Image

Bulletin 931S Standard Series Signal Conditioners provide additional functionality and application coverage over the Bulletin 931H series. They are available in compact sizes ranging 12.5…22.5 mm wide. These products provide isolation and conversion solutions for a wide range of current, voltage, temperature (thermocouples and RTDs), potentiometer, resistance, and frequency signals. These products also support line-monitoring, bridge rectifier (weigh scale), frequency, and signal splitting applications.

931U Universal Image

Bulletin 931U Universal Signal Conditioners provide the most functionality in a single unit. These signal conditioners are software programmable, which allow the devices to input and output a broad range of signal types. These products provide isolation and conversion solutions for current, voltage, temperature (thermocouples and RTDs), potentiometers, resistance, and frequency signals.

937C Converter Barriers
Contact Us
937C Converter Barriers Image

Our Bulletin 937C Converter Barriers add functionality to the isolators by receiving signals from a hazardous area instrument i.e., temperature sensors, or load cells, and then converting them to an industry standardized signal such as 0/4…20mA or 0/2…10V. Pulse evaluation units process a frequency signal at the input. A lead fault monitoring system signals a lead breakage or lead short-circuit on the signal cables.

937T Isolator Barriers
Contact Us
937T Isolator Barriers Image

Our 937T Isolator Barriers include galvanic optical or transformer isolation, these modules provide an interface within the intrinsic safety circuit that is electrically separated from the control system. A key advantage of isolated barriers is that they do not require a ground between the module and the intrinsically safe device. Available in 12.5 mm (0.5 in) and 20mm (0.8 in) widths.

937Z Zener Barriers
Contact Us
937Z Zener Barriers Image

Our Bulletin 937Z Zener Barriers provide protection for electrical signals within hazardous areas. These barriers feature a narrow profile of just 12.5 mm to maximize control panel space. They also prevent the transfer of unacceptably high energy from the safe area into the hazardous area. Our Zener Barriers include positive polarity, which means the anodes of the Zener diodes are grounded. Depending on the application, increased or decreased intrinsic safety parameters apply for serial or parallel connection.
