Fatek-B1-20M Main Unit – Expandable 20 Point PLC (12 In / 8 Out)

Fatek-B1-20M Main Unit is the standard, expandable model within the compact B1 series, designed to bridge the gap between micro-PLCs and larger modular systems. With 20 integrated I/O points (12 Inputs / 8 Outputs), this unit offers a robust starting point for automation projects that may require future scaling.

Description

Flexibility in a compact footprint is the defining characteristic of the Fatek-B1-20M Main Unit. It is engineered using Fatek’s streamlined System on Chip (SoC) technology, which integrates the CPU, Hardware Logic Solver (HLS), and communication peripherals into a single reliable chip. This design approach significantly enhances durability by reducing component count and increasing resistance to industrial noise.

The unit comes equipped with 12 digital inputs (24VDC) and 8 digital outputs (available in Relay or Transistor types). For precision control applications, the standard inputs include high-speed counting capabilities (up to 50KHz), and the transistor output models offer high-speed pulse outputs for servo integration. Crucially, the B1-20M distinguishes itself with its modularity; whether you need to add extra relay outputs later or integrate temperature sensors via the left-side bus, this main unit serves as a scalable foundation for diverse industrial applications.
