Allen-Bradley 2711-K3A17L1 – PanelView 300 Monochrome Keypad | PanelView 300 Series
Engineering Background
The Allen-Bradley 2711-K3A17L1 is a compact, keypad-only operator interface terminal from Rockwell Automation’s PanelView 300 series — a platform engineered for straightforward machine-level HMI applications in discrete and process manufacturing environments. Designed to interface directly with Allen-Bradley PLC families including SLC 500, MicroLogix, and PLC-5 via DH-485 or RS-232 communication, this unit delivers reliable operator control without the complexity or cost of full graphical displays.
Product Positioning
The 2711-K3A17L1 is the preferred choice for procurement engineers sourcing a proven, cost-effective keypad terminal for legacy system maintenance, OEM machine builds, or panel replacement projects. Its monochrome display, tactile keypad, and compact form factor make it ideal for environments where screen real estate is limited and operator interaction is function-key driven.

Proven Application Environments
- Discrete manufacturing machine panels requiring simple operator prompts and status feedback
- Legacy SLC 500 and MicroLogix control system upgrades or panel replacements
- OEM machine builders standardizing on Allen-Bradley HMI platforms
- Food & beverage, packaging, and material handling lines with NEMA 4/12 enclosure requirements
- Water/wastewater remote pump stations with minimal display requirements
- Retrofit projects replacing obsolete PanelView 300 units in existing control cabinets
Engineering Advantages
- Compact footprint — fits standard cutouts in existing enclosures, minimizing panel modification costs
- Keypad-only interface — eliminates touchscreen wear in high-vibration or gloved-hand environments
- Native DH-485 / RS-232 connectivity — plug-and-play with SLC 500 and MicroLogix without additional communication modules
- NEMA 4/4X rated front panel — suitable for washdown and dust-heavy environments
- Low power consumption — 24V DC operation compatible with standard PLC panel power supplies
- Proven field reliability — decades of deployment across global industrial installations
System Architecture & Signal Flow
The 2711-K3A17L1 connects to the host PLC via a single DH-485 or RS-232 serial link. Operator keypad inputs are mapped to PLC data table addresses (integer or bit files) configured in PanelBuilder software. The terminal polls the PLC at configurable scan rates, updating display strings and indicator states in real time. No intermediate gateway or communication bridge is required for SLC 500 or MicroLogix host controllers. For PLC-5 integration, a DH+ to DH-485 linking device (e.g., 1761-NET-AIC) may be required depending on network topology.
Sourcing & Quality Verification
- All units sourced from verified industrial surplus channels and authorized distribution networks

Technical FAQ
Q: Is the 2711-K3A17L1 compatible with Studio 5000 / Logix 5000 controllers?
A: No. The PanelView 300 series communicates via DH-485 or RS-232 and is not natively compatible with ControlLogix or CompactLogix (EtherNet/IP) platforms. For Logix-based systems, consider PanelView Plus or PanelView 800 series terminals.
Q: What programming software is required?
A: PanelBuilder 1400e (legacy) or PanelBuilder32 (recommended). PanelBuilder32 runs on Windows XP/7; a virtual machine environment may be required on modern workstations.
Q: Can this unit be used as a direct replacement for other 2711-K3Axx variants?
A: Physical mounting is compatible across the PanelView 300 keypad family. However, communication port configuration and application files must be verified against the specific catalog suffix before substitution.
Q: Do you provide a warranty?
A: Yes. Konmask provides a 90-day functional warranty on all verified surplus units. Extended warranty options are available upon request.
Q: Can you supply multiple units for a plant-wide retrofit?
A: Yes. Contact us with your total quantity requirement. Volume pricing and phased delivery schedules are available for project orders.
