Phoenix VIP-3/PT Series: FLK & D-Sub Industrial Interface Modules - Selection Guide
Product Overview
The Phoenix VIP-3/PT Series expands with specialized plug-in terminal (PT) interface modules, focusing on FLK protocol-compatible connectors and D-Sub (D25/D37/D50) interfaces for industrial automation systems. Designed for fast, tool-free wiring (PT terminal design), these modules support diverse connection needs—including FLK64/50/34/14 protocol integration, high-density D-Sub (up to D50) connectivity, hardware-coded (HW/C300) secure matching, and LED status indication. Featuring 35mm DIN rail mounting, robust construction, and compatibility with industrial controllers (e.g., PLCs), they’re ideal for sensor/actuator integration, PLC communication, and secure device matching in manufacturing, process automation, and control cabinet applications.
