Overview
The Turck BL67-8DI-P is a modular digital input slice for distributed industrial automation. This 8-channel input module accepts 24VDC PNP signals and is engineered for placement directly at the point of use. The BL67-8DI-P connects to a compatible base module via M8, M12, or M23 connectors, providing a fieldbus-independent solution for machine-level I/O.
