December 11, 2017 — Weidmuller introduced an addition in the Klippon Connect portfolio of products and services for panel building– maxGUARD. With maxGUARD, the electronic load monitoring ELM devices combined with distribution terminal blocks can be customized to provide selective load protection in 24V DC power distributed systems for industrial automation applications.
The modular maxGUARD system is designed to meet specific requirements for automation control panels. It contains three main cross-connection channels– positive, negative and internal signaling. This design increases the number of possible contacts from the electronic load monitoring device outputs (positive and negative) into the terminal blocks, providing connections for the distribution board loads. Integrated test points in maxGUARD’s terminals and a disconnect lever for load circuit galvanic isolation helps to simplify testing and troubleshooting.
Available in a range of single-channel and four-channel variations (both standard and conformal coating), maxGUARD is designed to provide application flexibility for custom solutions. The maxGUARD modules have a 6.1mm housing and feature push-in connection technology. The rated operating voltage is 24V DC, and the complete system has a maximum current capacity of 40A. The operating temperature range extends from -25°C to +55°C (without derating). The terminal cross-sections are 16mm² for the feed-in module, 2.5mm² for the electronic load monitoring (ELM), and 1.5mm² at the top and 2.5mm² at the bottom of the potential distribution terminal block. maxGUARD modules are cULus listed, Class 2 Certified (1A, 2A and 4A modules), CE rated and carry a range of global approvals. maxGuard can be pre-configured using the Weidmuller Configurator, a free software download available on the Weidmuller website.
