The Applications
1. Maintaining PLC Stability in Automated Production Lines
In automated manufacturing environments, programmable logic controllers and distributed I/O modules must remain powered to keep machines running accurately and safely. The PRO DM 20 diode module is used to connect two independent 24 V DC power supplies within control cabinets on assembly, filling, and packaging lines. If one supply fails or experiences voltage instability, the module automatically isolates it and maintains power to the control system. Its high current capability supports multiple devices, while the low voltage drop helps prevent control faults caused by undervoltage, ensuring smooth and predictable production processes.
2. Continuous Power for Industrial PC and Monitoring Systems
Industrial PCs and monitoring platforms rely on stable power to prevent system restarts and data loss. The PRO DM 20 is applied in control panels to provide passive redundancy between two DC power sources feeding computing and visualization equipment. When one power supply shuts down unexpectedly, the diode module ensures uninterrupted power without delays or software intervention. High efficiency reduces heat near sensitive electronics, supporting long-term reliability. This approach helps maintain continuous monitoring, protects operational data, and supports uninterrupted plant supervision in industrial automation systems.
3. Reliable Operation of Conveyor and Intralogistics Equipment
Conveyor systems and automated material handling installations depend on continuous power to avoid workflow interruptions. The PRO DM 20 diode module is commonly used in decentralized cabinets supplying controllers, sensors, and communication devices along conveyor lines. By isolating and combining redundant power supplies, it keeps essential control electronics operational even during partial power loss. Its durable metal construction and wide operating temperature range allow dependable performance in industrial environments where dust, vibration, or elevated temperatures are present, helping maintain consistent material flow and system availability.
4. Power Protection for Remote and Field-Mounted Automation Panels
Remote automation panels in pumping stations, utility infrastructure, or outdoor industrial sites often face unstable or fluctuating power conditions. The PRO DM 20 is used to secure power delivery to critical field devices such as remote I/O modules, gateways, and control units. Its diode-based isolation prevents reverse currents between power sources, reducing the risk of cascading failures. High current handling supports multiple loads, while efficient thermal performance ensures stable operation in compact enclosures, improving system resilience and reducing maintenance requirements.
