Please note the product does not come with power supply adapter that you may need. We offer suitable adapters with plug-in outlet or DIN Rail BOX on this link: http://denkovi.com/power-supply-adapters

The difference between the three types of relays is that JQC-3FC/T73 and RAS-12-15 requires 12VDC power supply and RAS-24-15 requires 24VDC power supply. JQC-3FC/T73 relays can handle max 12A/120VAC and RAS-12-15 / RAS-24-15 can max 15A/120VAC.

 

Application Examples

  • Home Automation
  • Industrial Automations
  • HVAC

 

Overview

 

 

Supported ModBus TCP commands

  • Read Coils (0x01)
  • Write Single Coil (0x05)
  • Write Multiple Coils (0x0F)
  • Write Single Holding Register (0x06)
  • Read Multiple Holding Registers (0x03)
  • Write Multiple Holding Registers (0x10)
  • Report Slave ID (0x11)

Warning: please note it is not possible to connect multiple devices from this type in single modbus network. This means the computer/smartphone is the master and the only Wi-Fi 16 Relay Module - TCP Modbus is the slave.

 

Control from Denkovi Wi-Fi 16 Relay TCP Modbus App

This is free software for easy configuration/monitoring/control the Wi-Fi 16 Relay Module.

 

Control from Android mobile apps

The Wi-Fi 16 Relay Module can be controlled/tested easily with DroidBus Android app

 

  

 

 

Control from iOS mobile apps

The Wi-Fi 16 Relay Module can be controlled/tested easily with Modbus Peek & Poke

 

 

Control from Windows

The Wi-Fi 16 Relay Module can be controlled/tested easily with Modbus Poll. Download the mbp description file for Holding Registers.

 

 

 

Packet Sender is also very useful tool for TCP/UDP packets sending. It supports GUI but there is also command line interface (CLI) which allows the relays to be controlled from command line

 

Controlling from command line console is also very easy. Here we have prepared some example commands for turning ON/OFF relays - download.

 

Configuration via Web Browser

The built-in web server provides ability for basic configuration of the module, like network settings, TCP/IP and UDP sockets parameters, wireless settings, passwords. Please note the relays can not be controlled via the web server!
