The ARM-CS radio modem operates with the license-free 868MHz band from 1 to 500mW (16 configurable channels). It ensures communication up to 5km in open field at the baudrate of 38,400bps.
Equiped in standard with RS232, RS485 and RS422 interfaces, it can be connected to most asynchronous devices as well as for « point-to-point » or « multi-point » radio communication (PLCs, PCs, SCADAs, acquisition devices, etc.). Under its metal IP65 housing, it is powered in 10-30Vdc and can operate in “low power” mode.

The radio modules ARM-IO 868MHz / 25mW have been designed to reply to a big demand of informations report in industrial harsh environments ( 400m) and outdoor at more than 1000m line of sight.
Fitted in a IP65 casing these modules are available in several versions: Digital (ToR), Analog (4-20mA, 0-10V), PT100 for temperature sensor, and Serial (RS232 / RS485). The ARM-IOD et –IOA can be Modbus slaves or work in mirror mode.
A very efficient sleep mode (250µA) allows to divide the consumption by 100, this way you can power the radio module with a small solar panel.
With the -LP (Low Power) version with Lithium battery, no external power is required, it can count pulses or transmit inputs states or physical values, etc... directly from the ARM-SE radio modem in Modbus / TCP or /RTU or in mirror mode with the ARM-X.

The ARM-LP Low Power Radio Module is powered by an internal 3.6V Lithium Battery, offering thus a range of several years (according to the utilization). Each module has its unique identification address.
This wireless module has: 2 digital inputs for alarm reports or pulses counting (AMR: Automatic Meter Reading).
2 analog inputs (0-2.5V), 1 PNP output (to power the external sensor) Battery Voltage monitoring
The polling of these modules can be done by using an ARM-SE radio modem (serial or Ethernet port) in Modbus RTU or TCP/Modbus
