Pengenalan Produk

This master controller forms the logic component of a modular door-interlock installation. It connects to separate input/output boards rather than carrying every door relay on the master itself. The arrangement separates sequencing logic from the physical wiring capacity and allows additional modules to serve larger groups of doors. The supplied item is the PLC master; connected I/O, locking devices and operator stations form separate parts of the assembled installation.

Ciri-ciri Utama

One master can address up to sixteen I/O modules.
Programmable sequences accommodate shared-door arrangements.
Module separation allows wiring capacity to grow independently of the master.
