    ™1 Vision OPLCs are programmable logic controllers that comprise an integral operating panel. Compactly designed, these controllers are compatible with different types of Unitronics’ I/O modules. This allows you to build Vision-controlled systems capable of automating a broad range of analog and digital applications. All Vision OPLCs offer RS232 communications, CANbus networking options, and a real-time clock (RTC).

  • Page 10: Technical Description

    Vision 230/260/280 User Guide Two types of I/O modules are compatible with Vision OPLCs. I/O modules are available in a variety of models. Snap-in I/O Modules plug directly into the back of a Vision OPLC, creating a self-contained PLC unit with a local I/O configuration. I/O Expansion Modules can also be easily integrated to greatly extend the system’s control capacity.
