Door Control PLC

The project

Nexora developed a programmable logic controller for door-control applications. The design brings digital I/O, analog conversion and wired communication into one control platform. The delivered work includes schematic design, PCB development and product testing.

The engineering challenge

The controller provides different interface types for equipment integration: digital channels for discrete signals, analog channels for measured or variable values, and Ethernet and RS485 for wired communication. Keeping those capabilities in one platform supports a coordinated door-control design. The field devices, communication protocol and control sequence remain application-specific.

Engineering scope

• 12 digital outputs rated at 1 A each; 12 digital inputs
• Ethernet and RS485 communication interfaces
• 4 analog-to-digital inputs and 2 digital-to-analog outputs

From circuit design to product testing

Nexora’s work on this product covers three connected stages. Schematics define the circuit and its interfaces. PCB development turns that design into a physical board. Product testing evaluates the assembled electronics against the intended operating requirements.

Where it can help

Relevant to door-equipment developers requiring an integrated controller. Installation design must establish the connected devices and electrical ratings; the portfolio’s digital-input current notation is not a confirmed input rating.
