GM7 & GM7U

GLOFA-GM Series

CPU, digital I/O and power are embedded in block-type PLCs, which is easy to Install in whatever 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).
