TETRA:
ETSI standard for public digital trunked radio systems.
is a standard framework for implementation of cellular digital
radio networks for voice and data, similar in some ways to GSM.

Wireless Technology for Everyone
The possibilities offered by wireless technology today are underestimated by almost everyone, largely because of a lack of awareness about it.
GSM-2110 and GSM-4110
Remote alarm signaling, control and data logging module
for GSM networks, with on-off inputs and outputs and
(optional) analog inputs. The GSM-4110 additionally has
PicoLogo micro-PLC functionality.

MDP-310.200H/M Master-Station Radio Modem
The MDP-310.200H acts as a radio modem and master
station for radio networks with up to 64 slave stations
RTU - Radio Remoter I/O Module
with on-off, analog inputs and on-off outputs.
Event counting and time totalizing functions can be enabled for on-off inputs. An optional PicoLogo Micro-PLC feature allows the RTU to act as an autonomous micro-PLC. All I/Os are electrically isolated from the module's electronic circuits.
TRM-710.200H - Radio Modem with serial interface
TRM = Telemetric Radio Modem
The TRM-710.200 Radio Modem is intended for use as a slave station in a radio network. It is accessed by polling, and transfers data between a
central control system linked to a remote master station and the serial port of the slave station.

PEM I/O Expansion Modules
Piciorgros Radio RTU Modules each have an I/O expansion interface  through which up to 16 PEM I/O Expansion Modules can be connected.
