Product Brief
7AI261.7 is B&R Series2003 screw‑in analog input module specially designed for strain‑gauge and load‑cell transducers. It supplies 5V excitation for 4‑wire full‑bridge sensors and captures weak 1‑16 mV/V measurement signals with 24‑bit high‑resolution conversion. Fixed 6 Hz update rate fits static and quasi‑static weighing and force‑monitoring tasks.
Module adopts screw‑in plug‑in structure,quickly mounts onto Series2003 backplane base unit. Galvanic isolation improves anti‑interference performance for industrial field environment. It is widely deployed in packaging,logistics and machinery equipment for weight detection and pressure‑force monitoring.
This is legacy EOL discontinued spare part,mainly used for old‑generation Series2003 automation system maintenance and hardware replacement. Before purchase,please confirm Series2003 backplane compatibility and sensor bridge parameter matching. ESD anti‑static protection shall be performed during installation. Do not plug/unplug module under powered‑on state.
