Product Brief

7DO138.70 is 8‑channel high‑current digital output module of B&R Series2003 control system. Compared with 7DO135.70,it provides higher per‑channel 0.5A output current,suitable for ordinary actuators requiring larger driving capacity.

Screw‑in plug‑in mechanical structure enables quick installation and replacement on Series2003 backplane base unit. Each channel integrates short‑circuit and thermal‑overload hardware protection to improve field‑site reliability. Galvanic isolation design reduces interference risk from field‑side 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 current requirement. ESD anti‑static protection shall be performed during installation,hot‑swap under powered‑on state is prohibited. Terminal block must be purchased separately.
