1 Introduction Spare parts availability

Micro-GC PRO Extension Boards User Manual 9

Spare parts availability It is the policy of Agilent to provide operational spare parts for any instrument and major accessory for a period of five (5) years after shipment of the final production run of that instrument. Spare parts will be available after this five (5) year period but on an as available basis. Operational spare parts are defined as those individual electrical or mechanical parts that are susceptible to failure during their normal operation. Examples include relays, lamps, temperature probes, detector elements, motors, etc. Sheet metal parts, structural members or assemblies and castings, printed circuit boards, and functional modules are normally capable of being rebuilt to like-new condition throughout their useful life and therefore will be supplied only on an as available basis after the final production run of the instrument.

2 General Information Extension Boards Concept

Micro-GC PRO Extension Boards User Manual 19

Extension Boards Concept The standard Micro-GC was developed to be used in combination with an external workstation that processes the data and controls external devices like relays, valves, etc.

In the process-market, there is a strong need to add extra analog and digital I/O functions to the Micro-GC.

If the Micro-GC is used as a PROcess-GC, the data-handling will be done inside the Micro-GC itself, no external workstation (software) is needed. The Micro-GC PRO calculates the final results itself and sends this information to an external process-computer, which also reads data from other devices in the process.

The Micro-GC PRO now controls the external devices (such as valves) and communication to process-computers which often takes place in analog form (0-10V or 4-20 mA).

The standard Micro-GC contains limited external I/O like two extra relays and several unused digital I/O lines.

The Extension Bus is designed to control external devices, like digital I/O, relays, DACs etc, over a relatively small distance (up to 10m). This bus is only intended for extension of the external I/O.

Several types of boards are developed to extend the number of digital I/O lines, relay-contacts and analog outputs. The basis is the Basic Extension Board containing the interface to the Micro-GC PRO. The maximum number of extension boards (including the Basic Extension Board) is three when using the GC to power the boards, and 8 when using an external power supply.

Figure 2. Extension boards connected to the 990 Micro-GC

2 General Information Housing and Mounting Options

20 Micro-GC PRO Extension Boards User Manual

Housing and Mounting Options All extension boards are prepared to be mounted in a baseplate. (Table 4 on page 16) A standard DIN-rail is used to mount the baseplate on a flat underground.

This makes it possible to stack all boards together onto one housing (with the Basic Extension Board mounted at the bottom) or to place each board in a separate housing (every extension board needing its own baseplate) and interconnect them via interconnection board cables.

If the boards are stacked together, spacers have to be used to maintain a stable construction.

Available extension boards:

2 General Information Power Supply

22 Micro-GC PRO Extension Boards User Manual

Power Supply All extension boards are powered by 12 volt DC.

Two power supply options are possible:

12 volt DC coming from the Micro-GC PRO. The maximum current is 500 mA (by electronic fuse). The maximum number of boards is three (3).

12 volt DC from an external +12 volt supply. This option can be used when galvanic isolation is required, or when more than 3 extension boards are connected.

Selection between the power sources must be done via jumpers (see Power Supply on page 22) on the Basic Extension Board. (Basic Extension Board on page 26)

CAUTION When using an external +12 volt power supply its mandatory to use the same power supply specifications as used in the Micro-GC Power Supply (document CP501267).

2 General Information Connecting Extension Boards

Micro-GC PRO Extension Boards User Manual 23

Connecting Extension Boards Extension boards contain parts that can be damaged by electrostatic discharge. Ensure you are properly grounded before handling.

1 To connect Analog or Digital Extension Boards on top of the Basic Extension Board replace the four corner screws with four standoff screws.

2 Place the board-connector in the Basic Extension Board.

All digital I/O channels are identical as on the Basic Extension Board on page 32. Each in- or output channel has also a green status LED indicating the state of the signal (low or high). Each relay has a red status LED indicating the relay on/off state.
