Radio I/O is up to 4 high precision sensor
4-20mA current loops (16 bit), 4 discrete, and 2
relays in an easy to install package. The
system creates a two-way wireless link between
remote site sensors and PLC or RTU SCADA system
nodes.
256-bit AES encryption is included
RF
Output Power: per FCC Part 15.249, 50mV/m
@ 3m
Providing reliable links from 1000' to >55 miles
NEMA 4X or Sub Zero enclosure
No field configuration is required

PROCESS RADIO CONTROL
Application
Example
Every input signal (0-10VDC, 4-20mA, digital) on
one wireless i/o radio appears as an output on
the other radio.
The radios are set up as pairs that emulate a
cabled connection. Nothing to configure or
calibrate.
I/O connects directly to labeled terminals.
Internal solar panel, battery charger, and
sensor
power supply make remote site applications easy.
1. 4-20mA sensors are powered by the 8200
internal Sensor DC supply.
Sensor current loops input to radio 1 are output
as loop-powered 4-20mA current loops on radio 2.
2. Grounding Digital INs on radio 1 causes
corresponding Relay OUTs on radio 2 to assert.
3. Likewise, inputs on radio 2 appear as outputs
on radio 1.
