Overview
The Turck BL67-B-4M12-P is a passive wiring base module for the BL67 modular I/O system, delivering a rugged, fieldbus-ready platform for distributed control at the point of use. Passive connection components for sensors and actuators, with quick replacement of electronics in wired state, this base module bridges factory and field installation requirements without costly rewiring cycles.
Key Features
- Protection class IP67 — sealed against dust and water ingress for outdoor and harsh-environment deployment
- M12 connection technology, 5-pin — standardized connectors ensure plug-compatibility across industrial platforms
- Mechanical coding prevents incorrect electronic modules from being plugged in accidentally — eliminates wiring errors and system damage
- On-machine modular I.O. (BL67 series) with DIN rail mounting (42mm width) — compact footprint for cabinet or panel installation
- 4 slots for paired M12 connectors — supports multiple sensor/actuator pairs in a single unit
