Glossary of Terms
AtlasPC™ Analog Combo board —An AtlasPC board with an analog format
that connects to the AtlasPC SmartCore board or PowerNet board, through
the PC/104 interface. It contains 15 analog inputs, 2 speed sensor inputs,
and 2 Analog outputs.
AtlasPC Pentium CPU board —An AtlasPC board with a Pentium processor, for
applications that require more horsepower than the SmartCore board, or
that require an Ethernet connection.
AtlasPC Power Supply board —An AtlasPC board with primary power supply
and 12 discrete outputs.
AtlasPC SmartCore board —An AtlasPC board with 4 analog inputs, 4 analog
outputs, 2 speed sensor inputs, 16 discrete inputs, and 3 serial
communication ports. This board includes both the PC/104 and the power
bus connections, allowing it to function as a backplane.
AtlasPC Power Supply board —An AtlasPC board with primary power supply
and 12 discrete outputs.
AtlasPC Chassis —A combination of pieces required to hold the boards
together, and may optionally include a keyboard and display.
AtlasPC Platform —The combination of boards, a power supply, and a chassis,
that can be combined to compose a variety of controls for a variety of
applications. The boards must have either a PC/104 connection, or a
proprietary power bus connection, and meet certain packaging constraints.
Analog Input —A 4–20 mA or 0–5 V input on the SmartCore board, and a
thermocouple, RTD or 4–20 mA input on the Analog Combo board.
Analog Output —A 4–20 mA output, usually the full range is 0–24 mA.
Backplane —A board that ties other boards together electrically. AtlasPC needs
either the SmartCore board, or the PowerNet board, to connect the power
bus voltages to the PC/104 bus.
Discrete Input —An input used for switches or other contacts, that registers only
two states, open or closed.
Discrete Output —Output drivers used for driving relays that register only two
states, high or low.
Serial Port —A connection for RS-232, RS-422, or RS-485.
Speed Sensor Input —An MPU or proximity probe input on the SmartCore
board, and a MPU only input on the Analog Combo board.
