Efficient machine and facility operations demand fail-safe and maintenance-friendly control voltage distribution installed in a time and space-saving manner. maxGUARD electronic load management from Weidmüller achieves this and much more with the introduction of the high-capacity ELM-18.
maxGUARD ELM-18 for Electronic Load Management up to 18 Amps, 24V DC
In the new maxGUARD system, the terminal blocks (previously installed separately) for distributing potential to the outputs of the electronic load management monitors become an integral part of a 24 V DC control voltage distribution system. Moreover, the specialised ELM-1 LIM CL2 EX variants also protect small loads with high input capacitances, such as sensors.
Combining load monitoring and potential distribution terminals saves up to 50% of space and up to 20% of wiring time. Furthermore, the flexible compatibility of many single-channel and four-channel variations optimises material costs.
Importantly, maxGUARD offers the benefits of a modular, highly flexible system for adapting into any application. It also provides ease of service during commissioning and maintenance with a disconnecting lever for simple galvanic isolation of load circuits.
Why the Electronic Load Management ELM-18 Module Stands Out
The ELM-18 module is for demanding 24V DC applications, capable of handling load protection up to 18 amps. This makes it one of the most powerful electronic load monitoring modules on the market today.
Designed for efficiency and durability, the module’s compact, space-saving build, and high operating temperature tolerance of up to 70°C make it ideal for industrial environments.
For industries requiring enhanced safety, the ELM-18 also includes a version with ATEX certification and a protective coating. This model is invaluable for rigorous environments like the process industry, where it offers dependable performance under challenging conditions.
With its adjustable tripping current of up to 18 amps, the ELM-18 can safeguard not only smaller control outputs and valves but also larger loads such as DC motors. This versatility makes it a perfect solution for any application needing robust, adaptable load protection.
Meet the ELM-1 LIM CL2 EX: Precision for Smaller Loads
Weidmüller did not overlook the needs of lighter loads either. The ELM-1 LIM CL2 EX variant is to protect small, high-capacitance loads, such as sensors. It ensures reliable operation even with smaller cable cross-sections under 0.25 mm². Both the ELM-18 and ELM-1 LIM CL2 EX modules meet the stringent UL 2367 standards for surge current protection, offering peace of mind in high-demand scenarios. Additionally, they serve as group fuses to protect many sensors simultaneously.
Space-Efficient Design with the maxGUARD System
At the core of the maxGUARD system is the integration of load monitoring and potential distribution in one compact package. Moreover, this smart design enables up to 50% savings in mounting rail space, allowing for streamlined installations and smaller cabinets. The modular, closed housing concept further increases flexibility, supporting a variety of installation configurations.
Empowering Customisation with the Weidmüller Configurator
Weidmüller simplified the setup process for their customers through the Weidmüller Configurator. Users can independently select and arrange components for a customised DIN rail assembly.
This digital engineering tool offers everything needed for a seamless configuration, from paperless assembly to data for automated production lines, empowering users with precision and control over their builds.
Weidmüller’s maxGUARD load monitoring management modules open new doors for effective, flexible, and efficient power management across diverse industrial applications.
