UHF Wireless Modbus RTU I/O Module 8DI 8DO RTU Module 2km PLC 8 Digital Inputs

I am pleased with them. It was a good choice for our small application. It is a robust device even it has a cheap price. I will use them in our further applications when we should use remote control. Thank you for your support.

—— Codreanu from Romania

Great news! We successfully performed the installation of the two units and transmitted our 4-20mA signal with both antennae. Even the smaller antenna suffices to transmit the signal without any losses whatsoever. So you can understand that we are very happy :) .

I believe you and your products. Sunny is very responsible. The RF modules are really strong and stable. Engineer's suggestions are useful to me. The most important is module's program can updrade on-line by myself. For some special projects, they can customize according my requirements. Thank you for your support all the time.

—— Singh from India

First of all I'd like to thank you for you're prompt service. The system now works perfectly. I left a positive response on your web site. I hope it attracts more customers for you.

Conveyor Control
Control a conveyor motor remotely

Remote Control Relay
Use dry contact inputs to control a remote relay.

Problem Notification
Save time in large facilities by activating an overhead notification light when a problem occurs, letting the supervisor know exactly where to go.

Dust Suppression
Use wireless I/O module to operate your dust

Data Logging
Wirelessly acquire and log various data from a remote location using our analog I/O module

Stacker Control
Start and stop your stacker/reclaimir. Connect PLC in control center with stacker and reclaimer.

Proximity Detection
Mount a transmitter with adjustable range on heavy equipment, mount a receiver in a “blind spot,” and then set up the receiver to sound an alarm or turn on a light whenever the equipment is operating in the area.

Chemical Level Monitoring
Monitor water chlorination or other chemicals remotely.

Traffic Signals
Avoid having to lay new wire by using wireless transmitters and receivers to control traffic signs such as “Railroad Crossing Ahead” when a train is present.

Grain Elevators
Our wireless transmitters and receivers can be used to monitor grain elevator conditions or control different functions. To collect RS485 data. To monitor temperature and humidity in Grain.

Freight Loading
Digital I/O module for crane control and analog I/O module to send the load information wirelessly to another location.
