OMRON NB7W-TW01B + CP1L-EL20DR-D Power Panel
The OMRON NB7W-TW01B combined with the CP1L-EL20DR-D PLC forms a complete, integrated power panel solution for small to medium‑sized machine control. This combination provides a compact, all‑in‑one control system that includes a 7‑inch wide‑screen touch HMI (Human‑Machine Interface) and a powerful CP1L series PLC with built‑in digital I/O. The panel is pre‑wired and configured to operate as a cohesive unit, significantly reducing engineering time and cabinet space compared to separate components.
The NB7W-TW01B HMI features a color TFT display with touch operation, offering an intuitive user interface for monitoring and controlling machinery. The CP1L-EL20DR-D PLC supplies 12 digital inputs and 8 relay outputs, suitable for handling basic sensing and actuation tasks. Together, they create a versatile platform for applications such as packaging, conveyor control, labeling, and simple assembly stations.
Component Specifications
NB7W-TW01B HMI: 7‑inch TFT, 800 x 480 pixels, touch screen, Ethernet and USB ports, backlight life > 50,000 hours.
CP1L-EL20DR-D PLC: 12 digital inputs (24 V DC), 8 relay outputs (250 V AC / 30 V DC, 2 A), USB programming port, expansion bus for up to 3 expansion units.
Communication between HMI and PLC: Built‑in Ethernet or serial link (RS‑232) – pre‑configured for plug‑and‑play operation.
Power supply: 24 V DC (both HMI and PLC) – panel includes a single power input with internal distribution.
Enclosure: Designed for panel mounting (cutout per NB7W dimensions) – includes all necessary mounting hardware.
Programming software: NB‑Designer (for HMI) and CX‑Programmer (for PLC).
Functional Capabilities of the Combined System
Centralized control: All control logic runs in the PLC, while the HMI provides operator interface, alarm display, and data entry.
Data exchange: The HMI reads/writes PLC memory (CIO, DM) via the communication link, enabling real‑time updates and recipe management.
Multi‑language support: The HMI supports up to 10 languages with text switching, ideal for exporting machinery.
Data logging: The HMI can log production counts, alarms, and operator actions to internal memory or USB drive.
Remote access: The HMI’s Ethernet port allows connection to a PC for remote monitoring and program transfer.
Typical Applications
Stand‑alone packaging machines: Providing operator control for bagging, sealing, and cartoning units.
Small conveyor systems: Monitoring speed, load, and fault status with an intuitive display.
Test stands and inspection stations: Displaying measurement results and guiding operators through testing sequences.
Educational/training equipment: Demonstrating integrated HMI‑PLC control systems.
Installation and Configuration
The panel is delivered with the HMI and PLC factory‑mounted and pre‑wired to a terminal block. The user only needs to supply 24 V DC power, connect field devices to the PLC’s input/output terminals, and connect the HMI to the Ethernet network (if remote access is needed). The communication settings between the HMI and PLC are pre‑configured, so no additional setup is required. The user can then download the application program to the PLC via the USB port and the HMI project via the USB or Ethernet port. The panel’s compact design allows mounting in a standard electrical cabinet, with the HMI protruding through the front door.
Compliance and Environmental
Both components are CE marked and UL recognized. They operate in ambient temperatures of 0°C to +50°C and are rated for pollution degree 2. The HMI front panel meets NEMA 4/IP65 for protection against dust and water spray.
Conclusion
The OMRON NB7W‑TW01B + CP1L‑EL20DR‑D power panel is an efficient, space‑saving solution for integrating HMI and PLC functions. Its pre‑integration reduces installation complexity, while its versatile I/O and display capabilities make it suitable for a broad spectrum of small‑scale automation projects.
