Mico Pro: modular current monitoring maximises machine uptime

Power supply systems are the heart of machines and systems and must be extremely reliable; Mico Pro is described as the guarantor of such reliability. This intelligent system monitors all load and control currents in a consistent manner and identifies critical moments at the right time. Mico Pro signals limit loads and switches defective channels off in a targeted manner. The tripping process, which has been patented, applies the principle of 'as late as possible, as early as necessary.' Mico Pro also identifies volatile errors.

Mico Pro is a modular system for 12V and 24V DC operating voltages. The components can be selected for the particular application from numerous Mico Pro modules and connected without tools via a power module to form a closed system. Users can select from modules with one, two, or four output channels. Their narrow width of 8, 12, or 24mm saves significant amojnts of cabinet space.

Module types

On the Fix modules, the tripping currents (2, 4, 6, 8, 10, and 16A) are fixed. On the Flex modules, the tripping current can be adjusted from 1-10A or from 11-20A. This increases flexibility and reduces the number of versions required. It is, however, possible to replace individual modules of the integrated network at any time.

Mico Pro has integrated potential distribution for +24 (or +12) and 0V that significantly simplifies switch cabinet wiring. There are connection options for +24V and 0V on each channel. Additional potential distributors enable connection of up to 2 x 12 potentials to each Mico channel.

The innovate bridging system, which consists of two bars and lateral spring contacts for connecting diagnostic and control signals, is easy to handle. It is designed for a total current of up to 40A. All system inputs and outputs are provided with push-in spring clamp terminals. The front side of the Mico Pro is at no time hidden by cables or lines, so the operator has a clear view of all designations and the status of the LEDs.

Diagnostics

Great importance is attached to the diagnostic functions of Mico Pro. Each channel is equipped with an LED for status indication on the device and digital status signals can be transmitted to the PLC. The Mico Pro power module provides group diagnostics for the entire system and the adjustable Flex modules offer channel-specific diagnostic signals.

LEDs for the individual channels indicate the states (green and red). Once the tripping current has reached 90 per cent, the LED flashes green and a digital status signal is triggered. If the tripping current is exceeded, Mico Pro immediately switches the affected channel off in a targeted manner. The LED flashes red and, in this case, a status signal is sent. The channel can be reactivated via a PLC signal or by pressing a button. For maintenance purposes, channels may also be switched off manually.

A channel-precise switching function via an SPS signal enables the Flex modules to switch system components on and off without any additional contactors, relays, or optocouplers. Not only can short switching frequencies (of up to 10Hz) be realised, but also longer frequencies.

Mico Pro can be cascaded. This means that on a Mico channel, another Mico Pro station can be connected. The savings in money and installation work are considerable, especially in the case of applications with a decentralised switch cabinet concept.
