RESA

What RESA does

RESA industrial Controls, Data & Power Solutions GmbH (trading as RESA iCDPS GmbH) is a privately held German industrial automation specialist headquartered in Lutherstadt Eisleben, Saxony-Anhalt. Founded in 1991 within the former Mansfeld AG plants, the firm designs, programs, builds, commissions, and maintains low-voltage switchgear, control panels, and automation systems for industrial customers. Its technology stack spans E-Plan P8 electrical CAD, PLC/SPS programming across Siemens S7, Rockwell, Wago, and VIPA platforms, network integration via PROFINET, EtherNet/IP, EtherCAT, CANopen, and POWERLINK, and IoT-enabled remote maintenance, organized under its iCDPS framework (industrial, Controls, Data, Power, Solutions). Two proprietary, trademarked product lines extend the offering beyond services: the RESA TECHNOMODUL TSK-system for low-voltage power distribution up to 1,000 V rated voltage and 7,100 A busbar current (IEC 439-1 certified), and the RESA Cube PV-DC surge protection box family (Cube 2.0/2.1/4.0/4.1) for photovoltaic installations.

The company operates a project-based business model with quote-driven, non-public pricing, focusing on custom and small-to-medium-batch switchgear solutions rather than standardized catalog products. Revenue is generated through engineering and planning services, control panel and switchgear manufacturing, PLC programming and visualization, maintenance contracts, and direct hardware sales of RESA TECHNOMODUL and RESA Cube units, supplemented by a photovoltaic installation service line for the Lutherstadt Eisleben area. Go-to-market is enterprise field sales targeting six horizontal segments — engineering firms, machine builders, factory planners, municipal utilities, building automation companies, and sensor technology firms — distributed through direct engagement, partner referrals (HEYFRA AG and TMS GmbH), and BVMW industry-association membership. Geographic reach is anchored in Central Germany with stated European and Asian customer engagements. The company has 11–50 employees, is led by Managing Director Dietmar R. Franke, and operates without disclosed external funding, parent company, or public financial reporting.
