Railway Computer RML-R 81X

Rolling-stock/Transportation Computer with 6 LAN interfaces – EN50155, OT4 and EN45545-2 certified

· Power Ignition controller · Inertial Measurement Unit (IMU) · GNSS with dead reckoning · 6x LAN

The Railway Computer RML-R 81X is based on the RSL-R81, but has six Ethernet interfaces and is expandable with digital I/O or analog inputs.

The Railway/Transportation Computer complies with the EN50155, OT4 standard. Further, the rugged box PC offers a power failure bypass of at least 10 milliseconds according to EN50155, Class S2 as well as full 50155 compliance with regard to shock and vibration (EN61373), EMC (electromagnetic compatibility) and electrical insulation requirements. In addition, the Railway Computer complies with the EN45545-2 fire safety standard for railway vehicles.

The Railway Computer including Ignition Controller is configurable for DC voltage between 16.8 and 137.5 volts via wide range inputs. The transportation computer can be optionally configured with 4G/LTE (UMTS/GSM fallback). Among other things, a high-accuracy GNSS function is possible. This allows the computer to achieve a positioning accuracy of one to two centimeters by means of RTK (Real Time Kinematic) surveying.
