The Railway signaling unit is used to receive the input signals from the field for validating and clearing route for trains. After receiving the signals, signals are isolated and various tests are done inside the system to ensure the received signals reliability and produce clearance signal to railway line. For security reasons card signature has been given to each card in the system. System consists of digital input modules, digital output module, digital read back module, RS232 interface with 80486 processor board. It is an ISA Bus Back plane based system.
