Yengear's wireless I/O sync module family is designed for remote dry-contact acquisition and interlocked control across separate areas, with point-to-point, one-to-many, mesh linkage, and sync switching architectures.

Model Naming Rule

Unified format: Y40A-BC-x

• A: architecture
  • 1 = Point-to-point
  • 2 = One-to-many
  • 3 = Mesh
  • 12 = Synchronous switching architecture
• B: number of DI channels
• C: number of DO channels
• x: communication type (L = LoRa)

Examples:

• Y401-11-L: point-to-point, 1DI/1DO, LoRa
• Y402-44-L: one-to-many, 4DI/4DO, LoRa
• Y403-11-L: mesh, 1DI/1DO, LoRa
