B&R 3AI775.6 System 2005 Analog Input Module 8p 0-20 MA Current Input 12 Bit Resolution

B&R 3AI775.6 System 2005 Analog Input Module 8p 0-20 mA Current Input

1.Overview of the B&R 3AI775.6

The B&R 3AI775.6 is a System 2005 analog input module. With eight 0–20 mA current inputs and 12-bit resolution, it can simultaneously monitor critical process values such as temperature, pressure, and flow on a single 170 × 120 × 50 mm card. With a linearity error of 0.1%, it brings laboratory-grade accuracy directly to the PLC rack. Backplane bus power is required, eliminating the need for additional terminals for plug-and-play operation, saving 30% of wiring time.
