A Perfect System to Monitor Current
Mico Pro is Murrelektronik's innovative 24 VDC current monitoring system. The modular design makes it possible to create systems that fit the application perfectly, which adds value by creating a cost-benefit ratio that saves space in the control cabinet. Murrelektronik's patented tripping behavior ensures maximum machine availability. An additional advantage is the integrated potential distribution concept. It significantly reduces the control cabinet wiring.
Overcurrent or short circuits can impact the power supply and cause machine downtime, production downtime and high costs. In order to maximize the reliability of the power supply systems, these problems have to be avoided. The Murrelektronik system consisting of high-quality power supplies and the Mico Pro power monitoring system, creates an optimum system with high machine availability.
In contrast to the miniature circuit breakers previously used, Mico triggers reliably even combined with long cables and the small cable cross-sections common in the 24 VDC range. This ensures long-term stable and error-free protection of load circuits in the 24 VDC range. With the intelligent Mico control cabinet component, Murrelektronik is able to quickly and efficiently design troubleshooting solutions, the end of long downtimes and a factor for reliable production processes.
Solutions that Fit the Application Perfectly
In order to meet the increasing requirements of automation technology in terms of modularity and miniaturization, Murrelektronik has further developed the Mico concept. With Mico Pro, Murrelektronik offers a modular solution: current protection systems can be designed that perfectly match the needs of users in their applications. The station has exactly the number of channels required for the specific application. The extensive portfolio offers versions with one, two, or four channels, which are either preset or can be flexibly adjusted for the applications. Extensions can also be implemented in the future without any problems. An additional module can simply be plugged in if further channels have to be protected.
In order to ensure the reliability of the Mico Pro stations, Murrelektronik works with quality awareness in all process steps. Murrelektronik's use of first-class components right from the development stage that are extremely efficient and are therefore not thermally stressed during operation. This results in a high MTBF value of over 2.4 million hours. Testing, for example with over 1,000 short-circuits, ensures the reliability of the components even in demanding situations. All this offers the dependability of a significantly long service life and regular availability.

Free Up Space in the Control Cabinet
The Mico Pro station can be designed with the exact number of slim modules required for the application, wasting no space in the control cabinet. As an additional option, power supplies specially developed for the Mico Pro system can also be integrated, they replace the power supply module and still offer the same diagnostics features: collective alarm message, 90 percent early warning, control signal for remote maintenance. The energy-efficient power supplies deliver up to 20 A in parallel mode and are connected intuitively and quickly using jumpers.
Another benefit Mico Pro offers that saves space are the potential distribution modules that connect several consumers with plus and minus (+24V and GND) to a monitored channel. This removes 0V distributions and the necessary terminal blocks from the control cabinet, freeing up a lot of space. The loads are directly wired to each channel and can be easily designated.
All this simplifies installations in the control cabinet and reduces the wiring effort. The result: lower overall costs.
Future-proof Applications
If the user has two or more control cabinets in a machine or system, two power supplies are no longer needed when using Mico Pro. With the innovative high-current modules (> 10 A), the power supply can be transferred selectively from a main distribution cabinet to a sub-distribution cabinet. This selectively guarantees that only the channel affected by the short circuit or overload is switched off.
Power-intensive consumers are increasingly being used in automation systems. Mico Pro provides reliable protection for these as well. M12 Power cables (L-coded) are the ideal interface to the IP67 products on the machine because they are designed for loads of up to 16 A and are defined as a standard by PI (PROFIBUS & PROFINET International).
