Relay (1C contact) output: 2 points Dry contact input: 3 points Models equipped with power relay and models compatible with small loads are available.

[ LA-2R3P-P(G) ] Equipped with a power relay, it can directly switch control loads ranging from 300W to 500W. This product is ideal for applications such as load switching control, forward/reverse control of motors, and electric lock control. [ LA-2R3P-PL(G) ] Equipped with a highly reliable relay that is less prone to contact failure due to oxidation even when used for switching small loads. It is optimal for switching control of power on/off for small power levels up to about 50W and for signal lines with low load currents.

Applications/Examples of results

■Ultra-compact and low-cost, ideal for distributed deployment By specializing in small-scale control applications, it achieves palm-sized compactness and low cost while incorporating a LAN interface. It is optimal for remote control applications where the control targets are dispersed within a factory and the required number of points per location is not high. ■Easy control from a computer You can control the input and output by sending simple control commands, as described in the user manual, in the payload section of TCP/IP. Units on the LAN can be identified not only by IP address but also by model number and ID number set with a rotary switch, ensuring that you can reliably identify the intended unit even when multiple identical models are connected to the LAN. ■Ability to develop a unique control system Input/output function libraries for Visual Basic, C++, and C# languages, as well as sample programs with source code (for LA-5R and LA-5P-P in a Visual C++ 6.0 environment), are available, allowing you to quickly develop a unique control system that integrates with other software running on a PC.
