Y401-44-L Wireless I/O Sync Module Manual

Refer to the full specification for electrical ratings, pinouts, and installation requirements: Y401-44-L Specification.

Overview

The Y401-44-L is a point-to-point wireless I/O synchronizer with 4DI/4DO. It mirrors digital inputs to remote relay outputs via sub-GHz LoRa for simple, license-free control links.

Basic Setup

1. Power the device with a stable DC supply as specified in the datasheet.
2. Wire dry-contact inputs to the DI terminals; avoid applying active voltage signals.
3. Connect relay outputs through NO/COM/NC according to your load type.
4. Mount the antenna vertically and keep it away from metal obstructions for best range.

Safety Notes

• Use certified power supplies and correct polarity.
• Do not install in explosive, high-humidity, or dusty environments.
• Keep the antenna within the specified operating band to maintain link reliability.
