Turck BL67-8DI-PD Distributed IO Digital Input Module

The Turck BL67-8DI-PD digital input module provides eight 24 VDC PNP inputs for the BL67 distributed I/O system, enabling reliable digital signal acquisition from field devices such as proximity sensors, photoelectric sensors, pushbuttons, and limit switches. Its IP67 machine-mount design allows direct installation on equipment, reducing cabinet space and simplifying field wiring in harsh industrial environments. The module features galvanic isolation from the field via optocouplers, channel diagnostics, wire-break monitoring, adjustable input filter times, and invertible input logic, with compatibility across M8, M12, and M23 base modules, and hot-swappable electronics for field upgrades. Technical specifications include 8 digital input channels, 24 VDC operating voltage, IP67 protection, and a compact footprint of 91 × 32 × 59 mm with a weight of 55 g, suitable for -40°C to +70°C operation and certified with cULus and CE approvals. Commonly used in packaging machinery, conveyor systems, assembly equipment, material handling, and manufacturing lines, this module supports distributed digital input acquisition across industrial automation systems and is ideal for control system expansion, I/O replacement, machine retrofits, and automation upgrades within the BL67 I/O platform.
