Description
Core Product Summary
The UNIOP EKDC-16 (Part Number: 6ZA933-7) is a panel-mounted industrial operator interface and HMI control terminal designed for PLC and machine-control interaction. Built within the EKDC series architecture, this unit features a 33-key physical ASCII keyboard layout and user status LEDs to facilitate direct operator command entry and status monitoring on automated industrial equipment.
Engineered for integration into standard control enclosures, the device operates on a standard 24 VDC industrial power supply. It provides robust human-machine interaction capabilities without relying on touchscreen displays, making it well-suited for legacy production environments, heavy manufacturing cells, and automated machinery where tactile physical buttons are preferred for reliable operation.

Detailed Product Overview
The UNIOP EKDC-16 (6ZA933-7) functions as an essential operator communication node within industrial automation networks. By interfacing directly with programmable logic controllers (PLCs) and machine controllers, the unit allows operators to monitor process variables, input parameters, and execute control commands.
Unlike modern graphical touchscreens, the EKDC-16 relies on a dedicated 33-key tactile keyboard configuration. This physical interface ensures dependable actuation in environments subject to vibration, oil mist, or where operators wear heavy protective gloves. The integrated user LEDs provide immediate visual feedback regarding machine status, fault states, or operational modes, supporting clear communication on the factory floor.
System integrators incorporating the EKDC-16 into an automation panel must verify communication driver compatibility with the host controller, establish proper 24 VDC power distribution, and ensure cutout dimensions match the physical enclosure requirements.
Dimensions, Mounting & Connection Notes
- Enclosure Mounting: Designed for flush mounting into industrial control cabinet doors or operator consoles using standard panel-fastening brackets.
- Power Connection: Connects to a standard 24 VDC power distribution terminal block.
- Operator Interface Layout: Incorporates a 33-key tactile ASCII keyboard and integrated status LEDs on the front membrane.
- Environmental Considerations: Protect against moisture, conductive dust, and excessive ambient temperatures by housing the panel within an appropriately rated industrial enclosure.
