What Digital Control Systems does

Digital Control Systems, Inc. (DCS) is a privately held Beaverton, Oregon-based designer and manufacturer of industrial control and sensing modules, founded in 1992 and operating with 11-50 employees. The company organizes its portfolio around three product lines: the AirSense family of Non-Dispersive Infrared (NDIR) CO2 sensors spanning low-cost PPM HVAC units (Models 308, 308T, 310e, 315 ULP), feature-rich multi-parameter units (Model 350), OEM embedded modules (300 series, 305e, 400), and network-capable units (Model 380); the ServoMax family of DC brush and brushless motor speed controllers (Models 200, 210, 220); and a custom OEM module design and manufacturing service. The underlying technical platform is built around dual-beam NDIR CO2 detection paired with the patented AdaptiveSense Technology (AST), a self-calibrating mechanism that automatically compensates for IR source degradation and sensor-wall reflectivity drift, eliminating routine field calibration.

Revenue mechanics are anchored in hardware sales across four streams: catalog CO2 sensor sales, motor speed controller sales, custom OEM module sales, and calibration kit sales. The go-to-market combines direct sales via the company website and phone/email with channel distribution through Dynacon and Kele for mid-market reach, plus OEM embedded sales delivering modules into thousands of third-party products worldwide. Pricing is not publicly disclosed and is structured as project-based for custom OEM work and standard catalog pricing for off-the-shelf products.

The customer base is organized vertically rather than by size: HVAC is the primary segment, with secondary exposure to laboratory/medical equipment OEMs, greenhouse operators, and general OEM manufacturers needing embedded sensing or motor control. Products are designed and manufactured in the USA, certified to UL, CSA, CE, and TÜV standards, and comply with the EU RoHS Directive. No venture capital or private equity funding rounds, acquisitions, or public-market activity are disclosed, consistent with a bootstrapped, founder-controlled specialty industrial manufacturer.

Core offering

Digital Control Systems designs and manufactures industrial CO2 gas sensors (AirSense brand), DC motor speed controllers (ServoMax brand), and fully customized OEM control modules. The AirSense line uses proprietary dual-beam NDIR detection and patented AdaptiveSense Technology for self-calibrating, low-maintenance CO2 measurement in HVAC, laboratory, greenhouse, and OEM embedded applications. The ServoMax line covers analog and digital controllers for DC brush and brushless motors, and the custom products business delivers fully bespoke sensing and control modules embedded inside customer products worldwide.

Product overview

Digital Control Systems offers a portfolio of industrial sensing and control products organized around three main product lines: AirSense CO2 sensors, ServoMax motor speed controllers, and custom OEM solutions. The AirSense CO2 sensor family includes multiple models (Models 308, 308T, 310e, 315 ULP, 350, 380, 300 Series, 305e, 400) ranging from entry-level HVAC sensors to laboratory-grade percent-range analyzers, all featuring proprietary AdaptiveSense Technology. The ServoMax family (Models 200, 210, 220) provides motor speed control solutions for DC brush and brushless motors. Custom Products enable specialized embedded control solutions for OEM customers. The company manufactures all products in the USA with compliance to UL, CSA, CE, TÜV, and RoHS standards.
