V120-22-R1 Unitronics V120-22 OPLC ,10/6 IO,1 ANA

Why Choose the Unitronics V120‑22‑R2C Vision™ 120 PLC + HMI?

The Unitronics V120‑22‑R2C is a rugged, all-in-one industrial controller featuring a monochrome graphic HMI display plus rich onboard I/O. With 10 digital inputs (including three configurable for high-speed counter/encoder), two analog inputs, and six SPST relay outputs, it delivers versatile automation capability. Dual RS‑232/RS‑485 ports, CANbus with UniCAN support, and MODBUS integration ensure flexible connectivity. Engineered for expansion up to 256 I/O, it’s built for compact controls, remote access, and reliable IP65 panel-mounted deployment—CE and UL certified for everyday and Class I Div 2 hazardous environments.
