TUV rated high voltage industrial controllers are required for mission critical control applications. High voltage controls with redundant fault monitoring, redundant interlock systems, and redundant parallel processors combine to make applications programs safe by design. OTEC control systems design has over thirty years experience in these types of designs. OTEC’s know-how provides proven circuitry where safety really counts.

STM32H745 features a dual core architecture consisting of ARM7 and ARM-M4 cores. Operating independently, GUI applications can execute efficiently while real time, mission critical applications run on the M4 core. Both cores share resources, but function autonomously. Application cross checking permits the implementation of safety rated output interlocks.

With over five years experience developing TouchGFX-based graphics applications, OTEC is uniquely positioned to rapidly develop custom GUI software. TouchGFX running with either capacitive or resistive touch screens presents an efficient user input system. TFT LCD displays are driven at high frame rates to a provide smooth and flexible graphics appearance.

Isolated high voltage input and output directly controls line voltages to external equipment. Multiple dry relay contact outputs are robust and reliable.

CAN Bus communications are accomplished over six independent, isolated CAN interfaces. Each CAN Bus can run at its own independent baud rate and addressing format. CAN Bus software gateways provide interbus data transfer.

The development of custom electronic products for our OEM clients is OTEC’s entire business. The design of custom Industrial Controller boards with rapid design cycles, demanding technical requirements, and unforgiving schedules sets us apart.
