MiniLink Compact Module Family

MiniLink is a family of compact industrial modules designed for space-constrained applications, with a consistent focus on small size, fast wiring, and lightweight deployment. The current lineup includes mini DTUs in the Y201 series and lightweight I/O modules in the Y301-110/020/200 series. It is suitable for equipment networking retrofits, cabinet I/O expansion, and rapid edge integration.

Selection Guide

1. Select the Y201 model by network type first: choose Y201-G for cellular public networks, Y201-W for wireless LAN access, Y201-R for wired Ethernet, and Y201-L for long-range low-speed wireless links.
2. Then select the Y301 model by I/O requirement: choose Y301-110 when both input and output are needed, Y301-020 for output-only control, and Y301-200 for status acquisition only.
3. During project implementation, review the corresponding technical manual first for default parameters, register mapping, and wiring diagrams to reduce commissioning time.
