Rosemount Model 751AM1 I8B Field Signal Indicator / Transmitter

Rosemount Model 751AM1 I8B Field Signal Indicator / Transmitter (4-20mA Input, ATEX EEx ia IIC T6, IP65)

The Rosemount Model 751AM1 I8B is a robust Field Signal Indicator and Transmitter designed for reliable operation in demanding industrial environments. Manufactured by Rosemount (an Emerson Automation Solutions brand), this unit provides a convenient method for locally displaying important process variables from any two-wire transmitter with a standard 4-20 mA output.

This device receives a 4-20 mA DC input signal from a connected field instrument, such as a flowmeter (like the Rosemount 8030), pressure transmitter, level transmitter, or temperature transmitter. It processes this signal to provide a local indication, typically on a scaled analog or digital display (depending on the exact meter option, but "Indicator" implies a display). It also functions as a transmitter, re-transmitting or conditioning the signal for integration into control loops or supervisory systems.

A key feature is its suitability for hazardous locations, backed by ATEX certification (Cert.: CESI AD - 82.020 X) with the protection marking EEx ia II C T6. This certifies it as Intrinsically Safe for use in areas with explosive gas atmospheres (Zone 0 or Zone 1), specifically for gas group IIC and temperature class T6. 

The Rosemount 751AM1 I8B features a durable enclosure with an IP 65 protection rating, signifying resistance to dust and water jets, suitable for harsh outdoor or industrial environments.

 This indicator/transmitter is often used in conjunction with the Rosemount 8030 Vortex Flowmeter.
