Product Brief

7CP476‑020.9 is top‑level expandable CPU of B&R Series2003 control system. Compared with 7CP476‑010.9,it adds one extra insert slot for dedicated interface modules,provides richer expansion possibility for special‑bus requirements.

Equipped with 750KB SRAM and 1.5MB FlashPROM,fits complex projects with large program and recipe data. CAN interface adopts galvanic isolation,supports CANopen for connecting remote I/O,drives and CAN‑based field devices. Screw‑in plug‑in mechanical structure enables quick replacement on Series2003 backplane base unit. Built‑in battery monitoring function reminds users of low‑battery risk in advance.

This is legacy EOL discontinued spare part,widely applied for maintenance and hardware replacement of old‑generation Series2003 automation production lines. Before purchase,please confirm base holder compatibility and expansion peripheral matching. ESD anti‑static measures must be taken during installation,hot‑swap under powered‑on state is prohibited.
