Description
Product Overview
The B&R 7AO352.70 is a compact 2003‑series analog output I/O module for B&R distributed automation systemsB& R Indus…. It delivers two channels of high‑precision analog output supporting ±10 V voltage and 0‑20 mA current modes with 12‑bit resolution. This screw‑in type module needs an external terminal block (7TB712.9 /7TB712.91) for field wiring connectionB& R Indus…. It translates internal digital control values into standard analog signals to drive proportional valves, positioning actuators and other analog‑controlled equipment, widely used in machine‑building and process‑automation retrofit projects.
