1. Overview

The Y412 series is a LoRa-based Wireless I/O Module family for dry-contact input acquisition and relay output control. It is designed for fast field deployment with minimal setup and is a practical replacement for long cross-area control wiring.

• Y412-22-L: 2DI / 2DO
• Y412-44-L: 4DI / 4DO
• Y412-88-L: 8DI / 8DO

The series supports master/slave mode, bidirectional follow or unidirectional feedback, and momentary or latching control. Typical applications include pump and valve interlock, lighting group control, and remote start/stop.

7. Installation and Wiring

Power Wiring

• DC version: connect V+ to positive, V- to negative, and PE to protective earth
• AC version: connect L to live, N to neutral, and PE to protective earth

DI Wiring

Supports 2-wire switches, 3-wire switches, and 3-wire sensors.

Installation Recommendations

1. Keep the same channel setting on all devices in the same communication group (DIP switches 1 to 5).
2. Keep the antenna away from large metal surfaces and strong interference sources.
3. Complete power and antenna wiring before setting the mode DIP switches.
4. For first-time deployment, validate a two-device link first, then expand to one-master/multi-slave operation.

8. Important Notes

1. DIP-based commissioning - The Y412 series is mainly configured through DIP switches and local keys. For field setup, refer to the User Manual.
2. Group consistency - Devices in the same group should use the same channel and key operating mode, otherwise linkage may fail.
3. Range vs. response - Response-priority mode provides faster action with shorter range, while range-priority mode favors distance.
4. Advanced parameters - Timeout reset and host-side parameters can be configured through RS485 or serial tools when required.
