The Vision V120-22-RA22 is a proven and highly reliable All-in-One industrial automation controller belonging to the classic Vision120™ series developed by Unitronics (Israel). By combining a high-performance Programmable Logic Controller (PLC), a 2.4-inch graphic LCD screen with an integrated 16-key operational keypad, and comprehensive onboard Input/Output (I/O) channels into a single palm-sized device, the V120-22-RA22 provides an all-inclusive automation solution that cuts panel space, eliminates external I/O wiring, and lowers equipment manufacturing costs for OEMs.

1. Crisp 2.4" Graphic LCD & Industrial Operational Keypad:
The controller features a 2.4-inch STN monochrome graphic LCD display with 128 x 64 pixels resolution and LED backlighting. The screen accommodates process variable displays, real-time trend graphs, bar graphs, and alarm logs. The front panel incorporates an integrated 16-key sealed membrane keypad (including numeric entry, arrow navigation, and 4 customizable function keys), enabling operators to enter setpoints quickly and accurately without removing protective work gloves. The front panel holds an IP65/NEMA4X ingress protection rating, shielding internal electronics against industrial dust and direct water spray.

2. Comprehensive Built-in Onboard I/O Configuration (RA22 Model):
The V120-22-RA22 is factory-equipped with a rich variety of integrated I/O points:
- Digital Inputs: 12 x 12/24VDC digital inputs (including 3 High-Speed Counter / Shaft-encoder inputs operating up to 10 kHz, 16-bit).
- Analog & Temperature Inputs: 2 multi-function inputs supporting direct temperature sensors (RTD PT100 / Thermocouple types B, E, J, K, N, R, S, T) plus 2 standard analog inputs (0-10V, 0/4-20mA) with high 14-bit resolution.
- Digital Outputs: 8 x Relay outputs (switching up to 3A load) and 2 x High-Speed Transistor outputs (pnp, PWM / PTO frequencies up to 10 kHz for pulse train stepper/servo control).
- Scalability: Easily expandable up to 256 local/remote I/O points via Unitronics expansion modules.

3. Fast Execution Engine & Flexible Industrial Connectivity:
- High-speed PLC processing engine executing bit logic operations rapidly (12 µs per 1K of typical application), supporting up to 4 independent Auto-tune PID control loops.
- Memory: 448 KB application logic, 256 KB for HMI displays, and 384 KB for custom fonts.
- Built-in Communication: Includes 1 x Isolated RS232/RS485 serial communication port.
- Optional Add-on Communication Modules: Second RS232/RS485 port, CANbus port (supporting UniCAN, CANopen, J1939), or Ethernet TCP/IP module.
- Protocols Supported: Modbus RTU (Master/Slave), Modbus TCP (via Ethernet card), CANopen, UniCAN, GSM/GPRS SMS notifications, and remote monitoring via Remote Access software.

4. Unified Free Single-Environment Software (VisiLogic™):
Both PLC ladder logic development and HMI screen design are programmed within the free VisiLogic™ software suite. Engineers eliminate the need to map cross-device tag databases between separate hardware, resulting in dramatically reduced commissioning time.
