Long-distance wireless transmission of analog contacts is possible via sub-gigahertz wireless.
The LA-3A3PP-SG is an IO unit that can monitor and control 3 analog output points and 3 dry contact input points. By using a gateway device, switching between voltage output and current output, as well as setting analog output values, can be easily performed with the accompanying software, and it is also possible to control it remotely from a user application using dedicated commands. This product can also be used as a high-precision voltage and current generator with digital inputs. It can be operated without being aware of the constraints of communication speed and transfer pause time under the SUB-GHz wireless standard, allowing control and monitoring signals to be transmitted up to 2 km in high-speed mode and up to 7 km in long-distance mode.

Applications/Examples of results
■Long-distance extension and optimal for distributed placement By utilizing sub-giga wireless communication in the 920MHz band, long-distance communication exceeding 1km is achieved. This allows for long-distance connection extensions that were not possible with the conventional wireless LAN IO series. The palm-sized compact housing, specialized for small-scale control applications, is also ideal for remote control applications where the control targets are dispersed over a wide area and the required number of points per location is not high. ■PC-less input extension function using sub-giga wireless By connecting oppositely through sub-giga wireless, the signal state of the input unit can be extended as the state of the output terminals of the connected output unit without using a computer. ■Ability to develop unique control systems A library of input/output functions for C++ and C# languages, along with sample programs with source code, are provided, allowing for the rapid development of unique control systems that integrate with other software running on PCs.
