Delta DOP-110CS HMI 10.1 inch 1024x600 Touch Panel 3 Serial
The Delta DOP-110CS is a 10.1-inch human machine interface from the DOP-100 series Standard range (C Type). It uses a 1024 x 600 high-resolution TFT LCD supporting 65,535 colours at 300 cd/m² brightness (typical), with an active display area of 226 x 128.7 mm and an LED backlight rated above 20,000 hours half-life at 25 °C — clearly readable under factory lighting.
The standout feature of the DOP-110CS is its three independent serial ports. Delta positions the Standard range as being "equipped with 3 serial communication ports to meet most customer requirements." Specifically: COM1 is RS-232 (with flow control, 9-pin D-sub); COM2 is RS-232 / RS-485 (with flow control); and COM3 is RS-422 / RS-485. This means one HMI can talk to three classes of device simultaneously — for example COM1 to a PLC, COM2 to a drive and COM3 over long-distance RS-422 to a remote instrument — with no extra serial expansion or protocol converter.
Key Features
- Three independent serial ports — COM1 RS-232 (with flow control), COM2 RS-232/RS-485, COM3 RS-422/RS-485; one HMI talks to three device classes at once
- COM3 supports RS-422 — differential full duplex with better noise immunity and longer reach than RS-485, for long-distance or full-duplex devices
- 10.1-inch 1024 x 600 high resolution, 65,535-colour TFT LCD at 300 cd/m²
- 226 x 128.7 mm display area — roughly 2.4 times the area of a 7-inch model, suited to showing many parameters together
- ARM Cortex-A8 at 800 MHz with 256 MB Flash ROM + 256 MB RAM
- Four-wire resistive touchscreen rated above 1,000,000 operations
- IP65 / NEMA4 / UL TYPE 4X front panel (indoor use only) — mounts directly on washdown machine panels
- Isolated power and serial ports; isolated power circuit withstands 1,500 V peak for 1 minute
- Two USB ports — 1 x USB Slave 2.0 (PC programming) + 1 x USB Host 2.0 (copy projects from a flash drive)
- CE / UL approved; vibration to IEC 61131-2 and shock to IEC 60068-2-27 (15 G peak)

Frequently Asked Questions
Does the DOP-110CS have an Ethernet port?
No. The hardware specification table in Delta's official DOP-110CS Instruction Sheet lists the "Network interface" row as N/A. Delta's description of the DOP-100 Standard range states that it is equipped with 3 serial communication ports, and that a separate "Standard Ethernet Type" provides an Ethernet port.
What is the difference between the DOP-110CS and the DOP-110WS / DOP-110IG?
The main differences are in communications. DOP-110CS (C Type, Standard): three serial ports, no Ethernet. DOP-110WS and DOP-110IG: fitted with an Ethernet port. All three have the same 10.1-inch screen and broadly similar display and processing platforms.
How should the three serial ports be allocated?
Allocate by cable length and protocol. COM1 (RS-232, with flow control) suits short-distance devices needing hardware flow control. COM2 (RS-232 / RS-485) is the most flexible — commonly used for drives and temperature controllers. COM3 (RS-422 / RS-485) should carry the long-distance or full-duplex link, such as an instrument across cabinets.
How do I choose between 10.1-inch and 7-inch?
Look at how much information must be shown and how large the cutout can be. The 10.1-inch display area is 226 x 128.7 mm, about 2.4 times that of a 7-inch model — suited to concentrated multi-parameter displays, trend curves and multi-unit overviews.
What should I know about power supply and consumption?
Use DC +24 V (−15% to +15%) from an isolated power supply. Maximum consumption is 10.4 W, and Delta recommends a power supply rated at 1.5 to 2 times the specified consumption. For heat dissipation, leave at least 60 mm at the rear.
What software is needed, and can existing projects be reused?
Delta's official DOPSoft software, free to download with no licence fee. The DOP-100 series supports upgrading and converting screens from the older DOP-B series — when replacing older models you can reuse existing projects, which shortens retrofit lead time considerably.
