1. Overview

The Y412 series is a LoRa-based Wireless I/O Module family for dry-contact input acquisition and relay output control. It carries input states between master/slave nodes and remote relay outputs.

• 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.

7. Installation and Wiring

Use the user manual for AC/DC power, DI, and relay wiring, DIP switch settings, and commissioning.

AC and DC supplies are separate hardware versions. Match the supply to the unit label. DI accepts dry contacts or NPN open-collector outputs; it is not a voltage input. Relay contacts require an external load supply.

8. Important Notes

• Use one master per communication group, matching channel settings, and compatible operating modes.
• Radio range depends on antenna placement, obstructions, interference, and air-data mode. Response-priority mode trades range for faster response.
• Timeout reset and advanced parameters are configurable through a compatible RS485/serial tool. Check the supplied settings before relying on communication-loss behavior.
• Local keys and wireless control do not replace an independent emergency-stop or personnel-safety circuit.
