Overview
The Turck BL67-4DI4DO-PD is a modular I/O solution designed for industrial automation and distributed control applications. This BL67 electronic module provides 4 digital inputs with integrated channel diagnostics and 4 digital outputs (PNP) in a compact, rugged form factor. The module operates at 24 VDC and is protected to IP67, making it suitable for harsh factory environments and field-mounted installations.
Key Features
- 4 Digital Inputs: 24 VDC with channel-level diagnostics and adjustable filter times
- 4 Digital Outputs (PNP): 24 VDC, 0.5 A maximum per channel
- Galvanic Isolation: Electronics isolated from field level via optocouplers for noise immunity
- IP67 Protection: Sealed enclosure withstands dust and water ingress
- Invertible Inputs: Software-configurable input polarity
- Status & Diagnostic LEDs: Visual feedback for module state and I/O activity
- Plug-in Mount: 32 × 91 × 59 mm compact profile
