The Electronics
The electronics are comprised of four main components:
• The low pressure pump main board (LPM).
• Power supply.
Optional:
• Interface board (BCD/external contacts).
• LAN Communication Card.
Low-Pressure Pump Main Board (LPM)
The board controls all information and activities of all assemblies within the
module. The operator enters parameters, changes modes and controls the
module through interfaces (CAN, GPIB or RS-232C) connected to the
user-interfaces.
The Main Power Supply Assembly
The main power supply comprises a closed assembly (no component-level
repair possibility). The power supply provides all DC voltages used in the
module. The line voltage can vary in a range from 100 – 120 or 220 – 240 volts
AC ± 10 % and needs no manual setting.
Optional Interface Boards
The Agilent 1200 Series modules have one optional board slot that allows to
add an interface board to the modules. Optional interface boards for the
Agilent 1200 Series are:
• BCD Board
• LAN Communication Card
