Turck BL67-8DI-PD 8-Channel Digital Input Module

The TURCK BL67-8DI-PD is an 8-channel digital input module for the BL67 distributed I/O and PLC automation system, providing 24 VDC PNP input acquisition from field devices in packaging lines, conveyors, and manufacturing equipment. It delivers eight PNP digital input channels suitable for monitoring proximity sensors, limit switches, pushbuttons, and photoelectric sensors, with galvanic isolation from the field via optocouplers and an IP67 machine-mount design for harsh environments. Key electrical specs include 24 VDC nominal input, a high-level threshold of 7–30 VDC, a low-level threshold under 4.5 VDC, high input current 2.1–3.7 mA, low current under 1.5 mA, and an input delay selectable at 0.25 ms or 2.5 ms, plus channel diagnostics and wire-break monitoring; inputs are invertible with adjustable filter times. The module consumes up to 30 mA from the module bus and up to 100 mA from the field supply, with a sensor supply current of 100 mA per two channels, and it can be mounted on BL67 IP67 field I/O stations using M8, M12, or M23 base modules. Operating temperature is -40°C to +70°C (storage -40°C to +85°C), dimensions 32 x 91 x 59 mm, weight 55 g, and it carries CE approval.
