FAQs
Installation is streamlined by direct CAN bus connections via RJ45 and the included mounting plate. Start by attaching the mounting plate to the enclosure, connect the sensor to the CAN bus network, and link to the PU compact and IoT interface as per the CMC III setup guide. The plug‑and‑play design reduces wiring complexity and speeds commissioning, with scalable expansion as your enclosure network grows.
The DK 7030.120 provides 2 x RJ45 CAN bus interfaces for direct CAN bus communication. It supports up to 32 participants per IoT interface, 4 PU compact, and 32 PU participants, with a maximum of 16 PDU devices. Connection is direct to the CAN bus, enabling straightforward integration into existing monitoring architectures and data collection across multiple enclosures.
Yes. Designed for IT, industry, and facility management environments, the infrared access sensor monitors enclosure door status, helping detect unauthorized access and trigger alerts. Its compact form factor (80×28×40 mm), direct CAN bus connectivity, and compatibility with CMC III processing units make it well suited for data center cabinet monitoring and security workflows.
The sensor operates from 0 °C to 55 °C and tolerates ambient relative humidity from 5% to 95% non‑condensing. This broad range supports deployment in data centers, industrial environments, and facility cabinets where temperature variations and humidity are common, reducing the risk of performance degradation or false readings.
The supply includes a mounting plate and assembly parts, enabling precise alignment and quick installation. This reduces on-site labor, improves mounting reliability, and simplifies future maintenance or sensor replacements within a bus network, contributing to lower downtime and faster ROI.
