Mass flow controller F4H

for gasdigitalcompact

The standard for mass flow controllers has just been raised. Description Azbil Corporation has added a new series of compact, easy-to-use products to its lineup of digital mass flow controllers equipped with a mass flow sensor that achieves 0,3 s high-speed controllability. Features Compact design saves space With a width of 28 mm, the F4H's slim design saves a great amount of space. All models are IoT-ready The large amount of data stored in the digital mass flow controller can be uploaded using the communication functions. This feature can be used not only to diagnose the mass flow controller, but also to diagnose the system that is using the mass flow controller. High noise tolerance By isolating the valve drive circuit from other circuits, power supply circuit and analog circuit isolation is achieved, even with a small-capacity isolated power supply. Thanks to this feature, noise from power wiring has no effect on signals. All models have digital communication capability, eliminating the effect of noise on analog signals. Additionally, highly noise-resistant 4-20 mA signals can be used. Reduction in overall cost By switching from an analog to a digital connection with the PLC, the analog I/O module can be eliminated and since the F4H series run on 24 Vdc, a dedicated +/- 15 V power supply is not required. The isolation of the power supply from the signal circuits, supplying power from a single source to multiple F4H units will not create a cyclic circuit.
