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.
Learn the basics of intrinsic safety circuits and how our Bulletin 937 Intrinsic Safety Modules can provide a cost-effective solution for hazardous location challenges.

FDT standardizes the communication and configuration interface between devices and control system or engineering or asset management tools. Examples include: PACTware™, FieldCare, FactoryTalk AssetCentre, and Process Device Configuration.
The Device Type Manager (DTM) provides a unified structure for accessing device-specific data, functions, and logic elements. DTMs range from a simple graphical user interface for setting device parameters to a highly sophisticated application that can perform complex calculations for diagnostics and maintenance purposes. DTMs can also implement arbitrary complex business logics for device calibration.
