Parameter

Application:

Wireless pump controls
Automate your tank level without running wire between the well pump and the tank. Wireless pump controls save you time and money.

Wireless tank level monitoring
simple wireless monitoring of your tank level from a remote location and receive critical status updates.

Wireless valve activation
Open or close electronic wireless valves, solenoid valves.

Smart Agriculture
Pivot irrigation, soil pressure and temperature monitoring

Emergency notification
Receive critical status updates by email, phone, cell phone, or PDA if equipment fails

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.

About value calculation
Analog input
Our analog module’s max measure range value is : 0X7FFF
1. Directly measure current and voltage
Exact value=value you read/0x7FFF*max range
For example: to read the 1st passage of module’s (with max range of 0-20mA) input value
Register 0x0008(analog input of the 1^st passage)
Feedback: 0x3801
Current value: (0x3801/0x7FFF)*20mA=8.7509mA

2. To measure sensor’s value(4-20mA, 0-6 meter level sensor)
If feedback value is less than 6554, level value is 0
If feedback value is bigger than 6554, level value=(value read-6554)/(32767-6554)*measure ranges
For example: feedback value is 0X3801, then corresponding level value is: ((0X3801-6554)/26213)*6 meter=1.7815 meter

Analog output
Analog module’s max measure range is: 0x7FFF
Directly control output current and voltage
Write register value=current or voltage value/measure range*0x7FFF
For example: to control the 1st passage of analog module whose max measure range is 0-20mA
Register 0x0048 (analog output of the 1st passage)
To write register value:(8.75/20mA)*0X7FFF =14336=0x3800
