DCIO2/MK-UL REXROTH

Description:

The Bosch Rexroth DCIO‑2/MK‑UL is a high‑performance digital I/O module designed for industrial automation systems. It delivers reliable input/output control and signal processing, specially built to integrate with Rexroth automation platforms and enhance system flexibility.

In operation, the DCIO‑2/MK‑UL enables precise digital signal interfacing—supporting multiple input and output channels, rugged environmental adaptability and streamlined integration in machine‑control networks.

Application Scenarios:

In a high‑speed automotive assembly line, a central automation controller manages dozens of sensors and actuators paging through conveyors, robots and inspection units. By deploying the Bosch Rexroth DCIO‑2/MK‑UL, the control system gains a modular I/O interface that simplifies wiring and installation, handles harsh manufacturing conditions (dust, vibration, variable temperatures) and reduces system downtime due to I/O faults. The module addresses key pain points such as scattered I/O locations, wiring complexity, and environmental reliability.

In another scenario—an offshore oil & gas platform’s control cabin, where ambient conditions are severe and system reliability is critical—integrating the DCIO‑2/MK‑UL ensures that digital signals from remote modules (valves, motors, alarms) are managed securely within the main automation rack, improving maintainability, reducing joint points, and aligning with rugged control standards.

Technical Principles and Innovative Values

Innovation Point 1: Modular digital I/O integration — The DCIO‑2/MK‑UL provides both input and output channels within one compact module, enabling flexible I/O configuration and reducing panel wiring complexity compared with traditional discrete I/O modules.
Innovation Point 2: Wide‑range voltage input compatibility — With 10‑30 V DC input range, the module can adapt to various control system voltage standards, reducing the need for separate power supplies and facilitating retrofit in mixed‑voltage environments.
Innovation Point 3: Rugged environmental design — Listings indicate IP67 protection and extended temperature ranges (–25 °C to +70 °C or –40 °C to +85 °C in some specifications) which help ensure reliable performance in harsh industrial environments (dusty, humid, vibration‑prone).
Innovation Point 4: Network/fieldbus interface readiness — Support for common industrial protocols (Modbus RTU, CAN‑bus) enables the DCIO‑2/MK‑UL to be integrated into distributed control systems or smart I/O networks, improving data accessibility and system transparency.
Innovation Point 5: Reduced footprint and improved maintainability — By consolidating multiple channels into a single module with compact dimensions, the DCIO‑2/MK‑UL helps optimise cabinet space, shorten wiring runs, and simplify maintenance compared to traditional architectures.

Compared to generic I/O modules, the DCIO‑2/MK‑UL stands out in offering rugged IP‑rated housing, higher channel density in a compact format, and industrial‑protocol readiness, which together increase uptime, decrease maintenance labour and simplify control‑panel design.

Application Cases and Industry Value

Case A – Automotive manufacturing line
A global car‑maker installed the Bosch Rexroth DCIO‑2/MK‑UL modules across its robotic welding cells. Prior to introduction, each cell had a mix of discrete I/O cabinets, long wiring runs and high incidence of connector faults due to vibration and welding‑fume contamination. After adopting the DCIO‑2/MK‑UL, the system achieved a 25% reduction in wiring time during cell installation, connector failures dropped by 40 % in six months, and maintenance technicians cited the ease of module swap–out as a major benefit. This improvement translated directly into higher line uptime and lower labour cost.

Case B – Offshore process‑control platform
On a marine platform control system, the harsh environment (vibration, salt‑air, limited space) demanded highly reliable I/O modules. By deploying DCIO‑2/MK‑UL modules in the main rack inside a climate‑controlled cabinet, the operators achieved reliable digital signalling between remote sensors/valves and the central PLC chassis. The rugged IP67‑rated design and compact footprint allowed the modules to be grouped densely within the 19‑inch rack, saving about 30% space versus previous I/O blocks. The result: simplified maintenance logistics, improved fault isolation and reduced spare‑parts inventory.
