## Overview

The LANTRO JS DC 12V RTU Relay Module is a compact, 16-channel serial port switch designed for professional automation control. Operating at 12V DC with a low standby current of 11mA, it supports up to 10A load per channel across various voltages. Featuring MODBUS RTU protocol compatibility via RS485, it enables seamless integration with industrial control systems, supporting up to 64 devices in parallel. Ideal for managing lighting, motors, and other electrical equipment with precision and efficiency.

## Description

Functions: 1. The working voltage is DC 12V. 2. The standby current (all closed relays) is 11MA, 1 open relay 40MA, 2 open relay 67MA, 3 open relay 95MA, 4 open relay 121MA, 5 open relay 147MA, 6 open relay 173MA, 7 open relay 198MA, 8 open relay 222MA … 3. 6 commands: "Open", "Close", "Momentary", "Self-Lock", "Interlock" and "Delay". 4. MODBUS RTU command control mode, the maximum delay is 255 seconds. 5. MODBUS commands can be done in HyperTerminal serial assistant or Enter "Modbus Poll". 6. In MODBUS command mode, this relay module can support up to 64 devices in parallel. Specification: Working Voltage: DC 12V Standby Current: 11MA Maximum load: 10A/250VAC, 10A/125VAC, 10A/30VDC, 10A/28VDC, 10A/12VDC Size: Approx. 17 x 6.5 x 2 cm/6.7 x 2.5 x 0.8 inches Weight: Approx. 225 g/7.9 oz Typical applications: MODBUS command mode (HEX), can control a variety of ways: Serial Hyper Terminal Control (you need to manually add CRC), Modbus Poll control software (the software automatically adds CRC), PLC process or MCU control. Wiring Diagram: 1. DC 12V control circuit, wiring diagram below. "LOAD" can be camera, LED lights, fans, motors and other DC 12V equipment. 2. Control circuit DC 1-100V or AC 85-265V, wiring diagram below (Note: if it is not DC 12V charging, need other DC 12V power supply). "LOAD" can be LED lights, fans, motors lights, fluorescent lights, solar water heaters and other DC AC equipment. Lis
