What this delivery is: one KOYO C-more EA7-T10C-S colour touch panel — the 10-inch class HMI from AutomationDirect's C-more (ViewJet) line — second-hand in fresh condition, three-month warranty, 3 kg, received 2026-02-02. The identity label carries the full record: EA7-T10C-S+05Z13B054, Date Code 5120, INPUT 24 V DC 17 W, KOYO ELECTRONICS INDUSTRIES CO., LTD., MADE IN CHINA, cULus Listed 87ML industrial control equipment, CE, and the panel-rating note — Meets UL Type 4/4x when mounted correctly, for indoor use only. The date code and the 2017.4 service sticker on the shell agree: this panel dates from 2017 production.

What the panel carries

Turn it over and the back panel tells you what it talks to. The communications row runs across the label: MIC IN and LINE OUT for audio, USB Programming for the panel's configuration software, a second USB for devices, and Ethernet for the PC/PLC link — with the DB9 serial COM1 port beside them for the legacy PLC connections the C-more line is known for. The LED silkscreen (PWR, CPU, TxD, RxD) sits by the serial port for a fast link status check. Power enters on the green pluggable terminal block marked +24 V DC, with the label's dedicated-power-supply recommendation beside it, and the unused auxiliary terminal positions are covered by the NOT USED blank. The CF/SD card slot on the rear spine handles project and data storage, and the four corner captive screws plus the gasketed bezel carry the Type 4/4x washdown rating — once it is properly mounted in a panel cutout.

In a control panel

The C-more line earns its keep as the mid-priced HMI that still talks to everything: the Ethernet port handles the modern PLCs, the DB9 serial port with its driver library still covers the legacy gear that a plant cannot retire, and the two USB ports split development from runtime so a laptop can stay attached without fighting a USB stick. The panel programs from PC-side software; projects upload over USB or Ethernet, and the card slot carries recipes and logs at runtime. At 24 V DC and 17 watts, the supply budget is trivial — one small DIN-rail supply feeds it — but the label's dedicated-supply note is worth honouring: sharing its feed with contactor coils invites resets every time something big drops out. The Type 4/4x marking is conditional, and the condition is the gasket: this panel is washdown-rated in the cutout with its gasket compressed evenly, not on a bench. The unit photographed here presents fresh — bezel unworn, film-era gloss on the shell, connectors clean — a panel pulled in good order and priced for a working spare.
