Industrial Emissions Control, Embedded Controller

Design Note #63

Custom Embedded Industrial Controller

Design of this custom embedded industrial controller required a lot of listening and patience, says our client. This low-volume, controller is implemented in a two board set. One board is a general purpose HCS12-based computer. The other board is an application-specific passive IO Board. Together these two boards provide input and output functions which can be efficiently setup for specific installation in a particular plant.

Replace Costly PLC's

Programmable logic controllers are an expensive general purpose way to implement industrial controls – but when volume grows into the tens and/or hundreds of units, a custom solution makes much more sense. Custom embedded industrial controllers from OTEC can reduce the physical size and power requirements of your control electronics while also reducing unit cost, simplify wiring interconnectivity, and improving reliability.

Microcontroller Performance

Many classes of low cost processors are available today. A Freescale HCS12 was selected for this design. It supports all control functions and implements an HTML web application for remote control, setup and data monitoring functions. Custom interlock circuitry insures operational safety.

Environmentally Tough

This custom industrial controller operates over extended conditions from –40 C to +85 degrees C; without fans. Designed for compliance with UL60950, EN60950, CSA C22.2 safety and EN61000 immunity requirements. Design Failure Mode Effects Analysis (DFMEA) techniques were used to insure fault-free operation by design.
