FAT-16MT-DC-E is a compact PLC with robust I/O features, high-speed communication, and versatile interfaces. It operates in challenging environments, offering precise control and diverse applications with SamSoar2022 software.

FAT-16MT-DC-E is a programmable logic controller (PLC) with the following features:

  • The main unit supports 4 high-speed pulse outputs and 4 high-speed counting inputs, providing powerful motion control capabilities.

  • It incorporates a CAN communication-based right-side expansion module, with a communication rate of up to 1Mbps, allowing for the expansion of up to 64 additional modules.

  • High speed is achieved through a compiled architecture, executing low-level code directly, resulting in speeds over 10 times faster than interpreted architectures.

  • Robust security features include password protection for uploading, downloading, monitoring, prohibition of uploads, folder passwords, subroutine passwords, and function block passwords.

  • It offers diverse communication interfaces, including 1 Ethernet interface supporting Modbus TCP/IP protocol, 1 RS485 communication port supporting Modbus RTU and custom protocols, and 1 high-speed USB download port.

  • Large storage capacity supports storage of user programs exceeding 20,000 lines and a 16KByte non-volatile memory area for power-down storage.

  • Accurate timekeeping is ensured with an external real-time clock chip.

  • Convenient clock battery installation is provided on the right side, allowing for easy removal and replacement of the battery.
