1. LS-RDIO0808 general introduction
    This is a 8DI8DO wireless RTU

     It has 8 digital input, 8 relay output

     There is a 1W RF module inside, it's OK to control 2km

2. Application Field
    LS-RDIO series I/O module is widely used in industry automation like factory central data process, pump control, oil monitoring, mining machinery, environment monitoring equipments, lifting devices, robots control, filling machine, mixing equipments, logistic line, AGV etc.

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.
