The Railway Computer RML-R 81 is based on the RSL-R81, but has additional COM interfaces and is expandable with digital I/O or analog inputs.
The Railway Computer RML-R 81 is meeting the standard EN50155, class S2. Furthermore, the railway computer offers a power failure bridge of at least 10 milliseconds according to EN50155, class S2 as well as complete EN61373 compliance with regard to shocks and vibrations, EMC (electromagnetic compatibility) and electrical insulation requirements. In addition, the industrial pc meets the fire protection standard for railway vehicles according to EN45545-2.
The railway computer, including the ignition controller, can be configured via wide-range power inputs for DC voltage between 16.8 and 137.5 volts. Optionally, the railway computer can also be configured with 4G/LTE (UMTS/GSM fallback). Among other things, it enables high-accuracy GNSS function. This feature gives the computer positioning accuracy of one to two centimeters via RTK (Real Time Kinematic) surveying.
