The FMA5400A/5500A mass flow controllers feature a built-in normally-closed electromagnetic valve for maintaining a constant flowrate regardless of variations in inlet or outlet pressures. The setpoint is controlled either locally via a potentiometer accessible through an access window in the case or remotely via an analog 0-5 Vdc or 4-20 mA signal (field selectable). The FMA5400A/5500A series require 12 to 26 Vdc power @ 800 mA maximum, which can be supplied by the FMA545PW wall plug-in socket power supply. 12 to 15 Vdc power @ 800 mA maximum (Sizes 43,44, and 45 ONLY). Model number FMA545C (supplied separately) provides a mating 15-pin “D” connector with 8 feet of shielded cable for accessing the analog output signals and power input connections. The LCD supplied with the FMA5500A series is connected to the lower electronics via a modular plug. The LCD can be remotely located by purchasing an FMA18RC remote cable assembly–you must then build your own assembly for panel mounting the LCD.

You get what you pay for
Works exactly as expected, like all Omega products.

Mass flow controller
It works great, very sensitive. Seller should provide a adapter with controllers to run

Love them
Great MFCs at a quick turn around, we use them in many applications. Some times in multiple flows.

Difficult to work with and incomplete manual
Mass flow controller is not functional with shop air.
