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.

Features

Uses integrated diagnostics for simple maintenance and quick change of modules during ongoing operation
Uses DIP switches or Field Device Tool software for easy configuration
Provides easy and reliable planning and documentation with comprehensive standards compliance up to SIL 3
Offers horizontal or vertical mounting with no reduction in operational ratings
Includes line fault detection for field circuits
Provides power rail for reduced wiring, collective error messaging, and efficient troubleshooting and installation
Isolates galvanic and break ground loops which avoids inaccurate I/O signal readings and limits energy to the circuit

Zener Barrier Intrinsic Safety Modules are used in any application with Class 1, Division 1 (Zones 0 and 1) hazardous locations such as:

Chemical
Petrochemical
Oil and Gas
