On-Board Electronics (OBE) forms a sub-system meant for high-end command, control system and data recording applications. The OBE consists of four cards, namely:

• CPU CARD
• I/O CARD
• POWER SUPPLY CARD
• MOTHER BOARD

OBE is an Intel processor based system and accepts single ended Analog inputs (16 Nos.) and TTL-OC Discrete inputs (16 Nos.) and processes the same. Processed Analog outputs (8 Nos.) & TTL-OC discrete outputs (16 Nos.) are made available for external interface. There are 4 Channels of RS422 Serial communication interface, and RS 232 Serial communication interface. OBE works with an input power supply of 28V DC.
