The KDE485 C programmable converter

The KDE485 C programmable converter is intended for rapid development of devices ranging from simple protocol conversion, Modbus interfacing, through data acquisition, telemetry, and all the way to complex products for the IoT market.

The customer is able to leverage in-house C programming expertise, and the license-free and widely used STM Cube IDE development kit protects his investment by avoiding restrictive practices in software licensing.

The KDE485 is offered in three versions:

The standard KDE485 has Ethernet and four serial ports. The API includes TCP/IP, TLS, HTTPS and this covers secure comms requirements with X509 encryption and authentication. Config and firmware updates are via USB, and can be accessed remotely via HTTP. There is also a 0-20mA output port, enabling the emulation of 4-20mA sensors.

The Isolated Analog version adds a 16 bit subsystem for sensing PT100, PT1000, all eight termocouple types, 4-20mA, and voltage.

The GPS-NTP version is intended for factory LANs where the highest security is required, mandating no internet connections, and it delivers GPS time via an NTP server on a user defined IP.

Other options include a 22 bit ADC, and ARINC429 which enables easy construction of products for the aviation and related markets. Other options can be rapidly developed using an internal expansion interface.

The KDE485 is powered from 11 to 28V DC, or 24V DC if its 20V sensor power output is required. The power input is isolated with a 1500V AC test voltage.

KK welcomes custom product enquiries which can be developed using the KDE485 as a platform.
