Roman Shulenkov,
Head of Industrial Automation Unit at Promwad

Our team has 20 years of expertise in schematic and PCB design, firmware, FPGA, and embedded Linux development to engineer your end-to-end solutions.

Custom hardware design

Promwad designs safety controllers, automation control modules, and sensors that meet Safety Integrity Levels (SIL) 1 to 3.

Each solution includes components for safety-critical applications, including fail-safe mechanisms and redundant architectures. This ensures minimal risk of failure and high operational reliability in process automation systems.

Embedded software development

We follow the IEC 61508 V-model to develop embedded systems, starting with requirements verification and system testing. Through design, integration, and module testing, we ensure your solution meets SIL levels 1 to 3.

At every phase, Promwad maintains compliance standards, integrating advanced diagnostics, real-time monitoring, and secure communication protocols with built-in redundancy and error handling to uphold system integrity.

Compliance support: consulting, validation, testing

With us, you can ensure the IEC 61508 compliance, starting with defining the environment, hazards, and risk analysis for the equipment under control (EUC). Our services include specifying overall safety requirements with a detailed allocation of functions and their target failure measures.

Promwad offers a complete safety lifecycle plan covering operation, maintenance, and validation, ensuring compliance throughout the system’s lifespan. We also provide thorough documentation, including the decommissioning or disposal of safety-related systems.

We developed an AC/DC servo drive with SIL 3 certification and integrated ten advanced protective functions for a European industrial automation manufacturer.

The servo drive is based on advanced and widely available electronic components and achieves high tolerance (1 failure per 10 million hours), maximising reliability and cost-efficiency for large-scale production.
