MECHANICAL /OPTICAL BLOCK INTERFACE SYSTEM (MOBIS)
To solve interference occurred in block communication for mechanical interlocking system, PT. Len already has a solution with a
product called Mechanical /Optical Block Interface System (MOBIS).
• MOBIS is an electrical signal produced by inductor which is converted into digital signals by Programmable Logic Controller
• Media conductors using optic cable
• The signals are converted back into electrical signals to move the solenoid, the destination station
• MOBIS system can be used as a solution to solve the problem of interfacing between stations equipped withelectrical
signaling and the neighboring stations equipped mechanical signaling system type S & H
