EJX430A PLC Direct Programmable Logic Controllers and Industrial Automation Products

The EJX-A series is Yokogawa's premium performance line of DPharp transmitters. Released in 2004, it offers the performance and stability needed in demanding applications. The EJX-A series performance makes it the the thoroughbred of the DPharp family of pressure transmitters.
The EJX430A is the Traditional Mount Gauge Pressure Transmitter in the series. The high performance gauge pressure transmitter EJX430A features single crystal silicon resonant sensor and is suitable to measure liquid, gas, or steam pressure. The EJX430A outputs a 4 to 20 mA DC signal corresponding to the measured pressure. It also features quick response, remote setup and monitoring via BRAIN or HART communications, and diagnostics. The multi-sensing technology provides the advanced diagnostic function to detect such abnormalities as an impulse line blockage or heat trace breakage. FOUNDATION Fieldbus and PROFIBUS PA protocol types are also available. All EJX series models in their standard configuration, with the exception of the Fieldbus and PROFIBUS types, are certifi ed as complying with SIL 2 for safety requirement.

FUNCTIONAL SPECIFICATIONS Output
