Product Brief

7AO352.70 is B&R Series2003 screw‑in analog output module. Two channels support software switching between ±10 V voltage and 0‑20 mA current output, flexible for different field actuators.

12‑bit digital‑to‑analog conversion provides stable analog control signal. Screw‑in plug‑in structure allows quick mounting and replacement on Series2003 backplane base unit. Built‑in short‑circuit detection monitors output status, convenient for equipment troubleshooting.

This is legacy EOL discontinued spare part,widely used for old‑generation Series2003 automation system maintenance. Before purchase,please confirm Series2003 base holder compatibility and actuator signal range matching. ESD anti‑static protection shall be performed during installation,do not plug/unplug module under powered‑on condition. Terminal block must be purchased separately.
