Y401-22-L Wireless I/O Sync Module Manual

Refer to the full specification for electrical ratings, pinouts, and installation requirements: Y401-22-L Specification.

Overview

The Y401-22-L is a point-to-point wireless I/O synchronizer with 2DI/2DO. It mirrors digital inputs to the remote outputs over sub-GHz LoRa, enabling simple, license-free control links.

Basic Setup

1. Power with a stable DC supply per the datasheet.
2. Wire dry-contact inputs to the DI terminals; do not inject active voltage signals.
3. Connect relay outputs via NO/COM/NC to your load as required.
4. Mount the antenna vertically and keep it clear of large metal objects for best range.

Safety Notes

• Use certified power supplies and correct polarity.
• Avoid explosive, high-humidity, or dusty environments.
• Keep the antenna in the specified operating band to maintain link reliability.
