Overview
The Turck BL67-B-8M8 base module is a passive connector backplane designed for Turck’s distributed I/O system. It features eight M8 3-pin connectors that accommodate both digital input and output modules from the BL67 family. This modular architecture allows control engineers to deploy field I/O directly at the point of use, reducing panel size and wiring complexity.
Key Features
- 8 M8 3-pin slots: Supports rapid swapping of digital input, output, and specialty modules without breaking field wiring
- Mechanical coding: Prevents accidental insertion of incompatible electronic modules
- IP67 protection: Sealed design rated for harsh factory and outdoor machine environments
- DIN rail mounting: 42 mm width for standard control cabinet installation
- Passive platform: Low power draw; pairs with active fieldbus modules (CANopen, PROFINET, EtherNet/IP, Modbus TCP, and others)
