●  The FBs-PLC provides 4 points hardware high-speed pulse width modulation output, with a resolution of 0.1% (for frequency 72Hz~18.432KHz) and 1% (for frequency 720Hz~184.32KHz), respectively. With high speed hardware, precision and stability, the FBs-PLC can easily achieve fine temperature control, proportional valve control, and simple
yet practical low cost D/A outputs.
