HMI touch panel · 4.3 in display, 480 x 272, 2 serial COM ports, USB · Delta Electronics DOP-103BQ

What this product is for

The DOP-103BQ is a compact human machine interface (HMI) for industrial automation systems. It gives operators a local touchscreen for machine status, control inputs, alarms, and process monitoring on equipment that uses serial communications.

Use for

Use for packaging machines, textile equipment, woodworking machinery, rubber and plastics equipment, and other control panels that need a 4.3 in operator interface. It is suited to applications using serial PLC or controller communications and local USB access for project download or data handling.

Avoid for

Avoid for applications that require a larger screen, Ethernet networking, or advanced wide-screen HMI functions. If your project needs more on-screen data, remote connectivity, or additional communication options, a higher-tier HMI may be a better fit.

Best for

Best for OEM panels and retrofit machine interfaces where panel space is limited and a basic 4.3 in touchscreen is enough for operator control. It is a practical choice when you need 2 serial COM ports and USB in a compact footprint.

Installed in

Typically installed in industrial control panels, machine operator stations, production equipment, and automation cabinets. Overall dimensions are 137 x 103 x 37.1 mm (approximately 5.4 x 4.1 x 1.5 in), with a mounting cutout of 118.8 x 92.8 mm (approximately 4.7 x 3.7 in).

Why this product exists

This HMI exists to provide a straightforward operator interface for general industrial equipment without moving to a larger or network-focused platform. It combines a 4.3 in TFT display, touchscreen operation, serial communications, and USB connectivity in one panel-mount unit.

Compared with similar products

Compared with older Delta 4.3 in HMI models, the DOP-103BQ is the current replacement for the discontinued DOP-B03S211. Compared with Ethernet-capable or larger-screen HMIs, this model is better suited to compact serial-based applications where basic local control is the priority.
