The Electronics
The electronics are comprised of four main components:
• The preparative pump main board (PPM), see “Preparative Pump Main 
Board (PPM)” on page 150.
• Power supply, see “Main Power Supply Assembly” on page 164.
Optional:
• Interface board (BCD/external contacts), see “BCD / External Contact 
Board” on page 155
• LAN Communication Card, see “LAN Communication Interface Board” on 
page 157.
 Main Board
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.
Main Power Supply Assembly
The main power supply comprises a closed assembly (no on-site repair 
possibility). The power supply provides all DC voltages used in the module 
except for the voltages supplied by the lamp power supply to the deuterium 
and tungsten lamps in the detectors.
The line voltage can vary in a range from 100 – 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
