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.

2.Core Features:

• Model: 3AI775.6
• Series: System 2005 Analog Input Module
• Channels: 8 single-ended inputs
• Input range: 0–20 mA (4–20 mA compatible)
• Resolution: 12 bit (0.05%, 4096 steps)
• Sampling period: ≤ 1 ms/channel
• Accuracy: ±0.1% F.S. (25°C)
• Isolation: 2500 V DC isolation between fieldbus and power
• Power supply: Supplied from the 24 V DC bus on the backplane, typical power consumption 2.5 W
• Dimensions/Weight: 170 × 120 × 50 mm, approximately 0.32 kg
