R108

The R108 from Schneider Electric serves as a robust compact rack/backplane intended for Modicon systems. This component is designed with eight slots, facilitating the integration of additional modules and devices. Operating at a nominal voltage of 5 VDC, the backplane ensures efficient functionality across connected devices while delivering a power rating of 75 watts.

With a backplane current capacity of 12 A, this unit can handle substantial loads while maintaining performance reliability. The data transfer capability of 1 Mbit/s ensures efficient communication between devices in the automation framework. Its operational conditions allow for a temperature range from 0 °C to +55 °C, supporting various environmental settings, while it can withstand storage temperatures between -25 °C and +70 °C.

This unit is protected against humidity, functioning correctly in environments with a relative humidity level ranging from 5% to 95% without condensation. Cooling is accomplished through natural convection, which is effective for maintaining system stability under normal operating conditions. Furthermore, the unit can be installed easily via cabinet mounting, making installation straightforward in appropriate enclosures. With an IP20 rating, the R108 offers basic protection against solid objects, ensuring durability within typical cabinet environments. Weighing in at 4 kg, the dimensions are compact at 178 mm by 482 mm by 150 mm, making it a practical choice for various configuration demands.
