16-Channel Micro PLC with Built-In I/O

Product Overview

The PLC-FB0808P is a compact, cost-effective 16-channel micro PLC built for small automation applications that demand reliable performance without complexity. Positioned as a smart relay replacement, this fixed I/O unit delivers advanced control functions including high-speed counting, pulse train output positioning, and real-time clock capability in a rugged, DIN-mountable housing. With both serial and Ethernet communication onboard, it integrates easily into existing automation networks. Programmed via the free MapleLogic software, the PLC-FB0808P supports multiple IEC 61131-3 programming languages for fast project development and simulation.
