RENU ELECTRONICS FP4020MR KEYPAD BASE HUMAN MACHINE INTERFACE MODULE REV.A3

The Renu Electronics FP4020MR is a compact and robust keypad-based Human Machine Interface (HMI) module from the FlexiPanels family. It integrates an operator interface with a built-in PLC controller, providing a cost-effective, all-in-one solution for industrial automation, machine monitoring, and local control applications . This model features a 16×2 character LCD with a tri-color backlight and an 18-key tactile keypad for intuitive operation .

Key Features

• Compact HMI with Integrated PLC: Combines a programmable operator interface with a powerful on-board controller using a Ladder Logic editor, enabling local control and logic execution without the need for a separate PLC .

• 16×2 Text Display: High-contrast, multicolor backlit LCD screen for clear status readouts, alarm messages, and data visualization .

• 18-Key Keypad: Includes 6 programmable function keys with integrated LEDs, which can be assigned to global or screen-specific tasks, plus a numeric pad .

• High-Speed I/O: Features 8 optically isolated digital inputs (bidirectional, 24VDC) and 8 digital outputs. It also includes 2 high-speed counter inputs capable of up to 25 KHz, ideal for counting, frequency, or speed measurement applications .

• Recipe Management & Data Logging: Supports recipe handling and alarm configuration (real-time and historical) for flexible machine setup and monitoring .

• Rich Connectivity: Offers a universal serial port (RS232/422/485) for connection to PLCs, printers, and other devices, alongside a USB Device port for fast programming and monitoring . The unit also features an integrated Real-Time Clock (RTC) .
