UHF Wireless I/O Module 8DI 8DO Wireless PLC 2km ON-OFF control
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.
