FAs-50MR-AC-E: Compact PLC with robust hardware, diverse interfaces, and versatile I/O capabilities. SamSoar2022 software ensures efficient programming. Ideal for industrial automation in challenging environments.

Product Description: FAs-50MR-AC-E

  1. Powerful Hardware and Software Configuration

    ● Hardware is based on a 32-bit microcontroller with Arm® Cortex®-M4 core, running at a main frequency of 200MHz. The hardware is enhanced for robust interference resistance, ensuring stability in the face of power fluctuations in the grid, guaranteeing continuous and efficient machine operation.

    ● The compiled low-level software ensures an extremely short scanning cycle, with execution speeds more than 10 times faster than that of a comparably configured interpreted PLC.

  2. Rich Communication Interfaces

    ● 1 Ethernet interface supporting Modbus TCP/IP protocol.

    ● 2 RS485 communication ports supporting Modbus RTU and custom communication protocols.

    ● 1 full-speed USB download port.

    ● PLC can be downloaded and monitored from any communication interface.

  3. Flexible and Comprehensive Performance

    ● The Ethernet host supports 8 channels of high-speed counting input and features robust motion control capabilities.

    ● Powerful instruction set.

    ● CAN communication-based expansion modules support communication speeds of up to 1Mbps, allowing for the expansion of up to 64 modules.

    ● Expansion modules can function as independent control units running programs.

    ● Supports 2 front-facing small plug-in expansion modules, allowing for the flexible combination of digital I/O modules, analog modules, and temperature modules for plug-and-play functionality.

  4. Upgraded Upper-Level Software SamSoar2022

    ● Compilation speed <0.5 seconds, download speed <3 seconds, and supports online program editing.

    ● SamSoar2022 supports instruction tables, function block diagrams, SFC step ladder diagrams, highly customizable user interfaces, and includes a rich set of PLC instructions. Users can write function blocks in C language.

    ● The software adopts a compiled architecture, ensuring resistance to decompilation and program cracking.

    ● The software has excellent compatibility with competitors, allowing for the direct conversion of ladder diagrams from the same category into visualized ladder diagrams.

    ● PLC programs can be downloaded through a visual control screen.
