Product Details

GM7 & GM7U

CPU, digital I/O and power are embedded in block-type PLCs, which is easy to install in the area you want for system configuration. In case of module-type PLCs, system configuration is easily achieved by a variety of modules (CPUs, I/O, special modules, network modules).
