Wireless I/O Radio Application:
Bidirectional 900 MHz or 2.4 GHz Spread Spectrum Radios Link 4-20mA Sensor Current Loops, Discretes, and Relay I/O

Model: DIN-R

Typical Site Application Diagram:

Synetcom wireless I/O application

Every input signal (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 DIN-R's 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.

For applications with more than two sites, or with expandable Wireless I/O requirements, use Synetcom's Serial SCADA Radio Modem with Radio Telemetry I/O Expanders.
