Product Brief

7DI140.70 is high‑speed digital input module of B&R Series2003 control system. Besides ordinary switch‑signal acquisition,it integrates hardware counter function to process incremental encoder and high‑speed pulse signals without occupying CPU computing resources.

Screw‑in plug‑in mechanical structure enables quick installation and replacement on Series2003 backplane base unit. Multiple channels can be independently configured via Automation Studio software for ordinary DI or high‑speed counting mode. It is widely used for position monitoring,length measurement and speed detection of packaging and automated machinery.

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 high‑speed pulse frequency matching. ESD anti‑static protection shall be performed during installation,hot‑swap under powered‑on state is prohibited. Terminal block must be purchased separately.
