MicroLok I

MicroLok is a microprocessor—based logic controller designed specifically for railroad vital interlocking applications. Its basic function is to process various inputs according to a program designed by the application engineer, and create the appropriate outputs.

Inputs and outputs may be through direct interfaces with MicroLok, or through serial communications with other vital or non—vital controllers. Direct inputs include track circuit occupancy, state of switch machine point contacts, state of signal relay or mechanism contacts, and traffic and line circuits. Outputs eventually interface to control signal mechanism drives, signal lamp drives, switch control contactors and traffic and line control circuits.
