Product Description

The UNIOP 33A-BKDC16-T is a versatile universal operator panel (HMI) from the renowned UNIOP family, designed to provide a reliable and flexible interface between operators and industrial control systems. This panel combines a compact 5.7-inch TFT color touchscreen with 16 programmable physical function keys, offering a balanced solution for applications where both visual clarity and tactile feedback are essential .

 

Application Scenarios

Imagine a food processing plant where operators must wear gloves and frequently interact with machinery in a wet, washdown environment. The UNIOP 33A-BKDC16-T is mounted on the equipment door, its IP65-rated front panel resisting water jets and dust . Operators use the physical keys—each labeled with a custom-printed tag—to start, stop, and reset the line, while the color touchscreen displays real-time production data, alarm messages, and recipe selection menus. This hybrid interface solves the core pain points of needing both rugged physical controls for critical functions and a flexible display for dynamic information, all without requiring a complex, expensive PC-based HMI.

In another scenario, a plant upgrading a legacy SLC 500 control system can deploy the 33A-BKDC16-T as a modern operator interface without rewriting the PLC’s core logic. The panel’s built-in driver for Allen-Bradley DF1 protocol enables direct connection to the PLC’s programming port . This cost-effective solution breathes new life into older machinery, enhancing operator efficiency and diagnostic capabilities while preserving the existing control infrastructure.
