Description
Product Introduction & Engineering Value
The 2711C-K3M is a small PanelView Component terminal built for straightforward machine-side control. It uses a monochrome display and keypad interface, which makes it useful on equipment where operators need a simple, durable panel instead of a larger touchscreen HMI.
Its value is practical, not flashy. For legacy MicroLogix, Micro800, and serial-connected machines, it gives you a compact operator station with low panel footprint and familiar Rockwell integration behavior.

Field Application & Trench Experience
A small OEM had a legacy machine with a failing operator panel that only needed basic recipe selection and status prompts. The 2711C-K3M fit because it matched the low-complexity interface, took almost no panel space, and could still talk over serial without forcing a controller redesign. The real win was keeping the machine supportable with parts the maintenance crew already understood.
You will usually see this terminal on compact skids, small packaging machines, and utility panels where the operator interaction is simple but must remain reliable and easy to replace.
Transparency SOP: QA & Testing
- Visual inspection for bezel cracks, keypad wear, liquid damage, and connector corrosion.
- Power-up verification of display contrast, backlight, and key response.
- Serial communication test on the supported protocol path, usually DH-485 or DF1.
- Menu or application load verification where a test image is available.
- Extended run check to catch intermittent keypad or display issues before shipment.

Veteran’s Tech Trap Guide
⚠️ Don’t treat it like a touchscreen terminal. This is a keypad-driven PanelView Component unit, and the operator workflow is very different.
⚠️ Verify the serial protocol before replacement. If the original machine used DH-485, DF1, or another supported serial path, the new unit has to be set up the same way.
PRO TIP: Check the cutout and mounting depth before you order. These compact panels are easy to specify wrong when the old bezel is damaged and no one measures the opening.
Dynamic FAQ
Q1: Is the 2711C-K3M a direct replacement for an existing PanelView Component C300?
A: Yes, if the original catalog number and serial communication setup match.
Q2: What type of display does it use?
A: A 3-inch monochrome transflective FSTN passive matrix display.
Q3: What communication methods does it support?
A: RS-232 and RS-485, with supported use cases including DH-485, DF1, Modbus, and Siemens MPI.
Q4: What power does it require?
A: 24 V DC.
Q5: Is this sold as new surplus or refurbished stock?
A: Either is common. New surplus means unused OEM inventory, while refurbished means tested and restored for reuse.
Q6: Does it come with warranty coverage?
A: Warranty depends on the seller, but reputable industrial suppliers generally offer coverage on both new surplus and refurbished units.
