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.
