Short‑circuit diagnosis facilitates quick field fault troubleshooting.

Product Brief

7DO135.70 is B&R Series2003 four‑channel FET digital output module. It supports three working modes, not only general‑purpose switch output,but also PWM pulse‑width modulation and TPU hardware high‑speed output,well‑matched with TPU‑enabled Series2003 CPU for motion‑related control tasks.

Screw‑in plug‑in mechanical structure enables quick installation and replacement on Series2003 backplane base unit. Built‑in channel diagnosis function monitors short‑circuit and overload status. Galvanic isolation design reduces interference caused by field‑site noise.

This is legacy EOL discontinued spare part,widely used for maintenance and hardware replacement of old‑generation Series2003 automation equipment. Before purchase,please confirm Series2003 base holder compatibility and actuator load requirement. ESD anti‑static protection shall be performed during installation,hot‑swap under powered‑on state is prohibited. Terminal block must be purchased separately.
