FAQs
Installation is straightforward: mount the DK 7030.430 using the supplied mounting plate and assembly parts, then connect the external sensor and the CAN bus via two RJ45 interfaces. The device is designed for plug‑and‑play operation, with automatic detection once connected to the PU network, reducing commissioning time and wiring errors.
Conductivity measurement detects moisture presence by sensing electrical changes in the enclosure environment. This enables rapid alerts to IT and facility teams, minimizing the risk of unseen water ingress. The system supports fast connection to CAN bus networks, enabling timely fault isolation and targeted remediation.
Yes. The sensor connects directly to CAN bus using 2 x RJ45 interfaces and is designed for use within PU networks. It supports up to 32 IoT participants per interface and up to 32 participants per PU, making it suitable for scalable deployments across IT racks and industrial enclosures.
The product data references ETIM 9 EC002627 and ECLASS 8.0 27189253 classifications, which support procurement and interoperability. The cradle-to-gate PCF is 1.1 kg CO2 eq (Cat B). For regulatory certifications beyond classifications, consult Rittal's documentation or the supplier for CE marking or IP ratings specific to your region.
The plug‑and‑play design reduces installation time, while continuous enclosure monitoring lowers downtime risk and repair costs. With durable construction, a compact form factor, and a clear path for scalable deployments (up to 32 IoT participants per interface), the sensor supports lower maintenance costs and faster ROI in IT rooms and industrial facilities.
