Access controller Rittal DK 7030.233 – black, access control module (50 × 25 × 190 mm)

Rittal DK 7030.233 is a compact black access controller designed for integration into access control and security systems. With dimensions of 50 × 25 × 190 mm, the module provides a small footprint suitable for installation in industrial enclosures and IT cabinets. It offers a control interface for reader and transponder systems and is supplied as a single unit intended to enable secure, reliable access management where space is limited.

Advantages

The access controller combines a slim mechanical design with standard electrical connections to fit into existing cabinet layouts. Its compact dimensions and unobtrusive black finish make it suitable for visible mounting in professional environments. The module is engineered to provide consistent signalling for reader and transponder devices, supporting predictable operation and straightforward integration into broader access-management systems.

Suitable for

• Integration into industrial control cabinets and electrical enclosures
• IT racks and server cabinets where controlled physical access is required
• Connection to card readers and transponder systems in small- to medium-size installations
• Retrofit projects where a low-profile access control module is needed

When it may not be suitable

This module is intended as an access control interface and does not include standalone reader electronics, power supplies, or network controllers. It may not be suitable where a fully integrated, standalone access terminal or a weatherproof outdoor reader is required. For systems that demand advanced features such as integrated biometric sensors, onboard databases, or high ingress protection ratings, a different product class may be more appropriate.

Key specifications

• Form factor: compact module with dimensions 50 × 25 × 190 mm
• Colour: black (RAL 9005 typical finish)
• Mounting: designed for installation in cabinets and enclosures
• Function: control interface for reader and transponder systems
• Supply: supplied as a single module for system integration

How to use

Install the module inside the cabinet or enclosure at a location that allows convenient routing of reader and transponder wiring. Connect signal and power lines according to the system wiring diagram provided by the access control system integrator or manufacturer documentation. Test the connected reader and transponder devices after installation to verify correct signalling and reliable operation. Ensure that enclosure covers are closed and any required earthing/grounding is applied to maintain EMC and safety standards.

What to consider before purchase

• Compatibility with existing reader and transponder hardware and wiring conventions
• Space available inside the cabinet for a 50 × 25 × 190 mm module and associated cabling
• System requirements for power, signalling levels, and any required interfaces
• Environmental conditions inside the enclosure (temperature, humidity) and whether additional sealing or protection is necessary

Usage recommendations

For reliable performance, install the module in a dedicated compartment within the cabinet, keep signal cables separate from high-voltage lines, and follow manufacturer guidance for grounding and EMC mitigation. Coordinate wiring and addressing with the central access-control unit to ensure seamless integration with reader and transponder devices.
