CUTLER HAMMER 1785K-PMPP-1700 Touch Panel – Operator Interface for PLC-5 Platform
Engineering Background: The 1785K-PMPP-1700 is a dedicated touch panel operator interface engineered by Cutler-Hammer (an Eaton brand) for integration with Allen-Bradley PLC-5 series programmable logic controllers. Designed for demanding industrial environments, this HMI provides direct operator interaction with PLC-5 control programs via a resistive touch display, enabling real-time process monitoring and parameter adjustment without a separate programming terminal.
Product Positioning: Targeted at maintenance engineers and system integrators managing legacy PLC-5 installations in manufacturing, utilities, and process industries. The 1785K-PMPP-1700 is the preferred replacement and upgrade path for facilities requiring continued HMI support on existing PLC-5 backplane architectures without full system migration.

System Architecture & Signal Flow
The 1785K-PMPP-1700 connects directly to the PLC-5 processor via the designated communication port (DH+ network or RS-232 serial link). Operator inputs on the touch screen are translated into PLC data table read/write commands. The HMI polls the PLC-5 data files at configurable scan rates, displaying real-time process values, alarm states, and setpoints. Configuration and screen programming are performed offline via compatible HMI development software and downloaded to the panel via serial or network connection.
Signal Flow: Operator Touch Input → HMI Controller → PLC-5 Communication Port → PLC-5 Data Table → HMI Display Update

Technical FAQ
Q: Is the 1785K-PMPP-1700 compatible with ControlLogix or CompactLogix PLCs?
A: No. This panel is specifically designed for the Allen-Bradley / Cutler-Hammer PLC-5 platform. For ControlLogix/CompactLogix, a different HMI model with EtherNet/IP support is required.
Q: What programming software is required to configure this touch panel?
A: Configuration is performed using the OEM-specified HMI development software compatible with the 1785K series. Contact our technical team for software compatibility guidance.
Q: Can Konmask.com provide a warranty on this unit?
A: Yes. We offer a standard 90-day functional warranty on all tested surplus units. Extended warranty options are available upon request.
Q: What is the typical lead time?
A: In-stock units ship within 1–3 business days. For out-of-stock items, sourcing lead time is typically 5–15 business days depending on availability.
Q: Is DDP (Delivered Duty Paid) shipping available?
A: Yes. We support DDP, DAP, and EXW Incoterms. Please specify your preferred trade term when requesting a quote.
