9-2 Model 49i Instruction Manual
A 5-10 micron pore size, two-inch diameter Teflon® element is available for
Filter
the Model 49i. This filter should be installed just prior to the SAMPLE
bulkhead. When using a filter, all calibrations and span checks must be
performed through the filter.
The I/O expansion board provides six analog current output channels (0-20
mA or 4-20 mA) and eight analog voltage inputs (0-10V). The DB25
connector on the rear panel provides the interface for these inputs and
outputs.
The optional terminal block and cable kits provide a convenient way to
connect devices to the instrument. These kits break out the signals on the
rear panel connector to individual numbered terminals.
Two types of terminal block and cable kits are available. One kit is for the
DB37 connectors and can be used for either the analog output connector or
the relay output connector. The other kit is for the DB25 connector and can
be used for the optional I/O expansion board. For associated part numbers,
refer to "External Device Connection Components" in the "Servicing"
chapter.
Each kit consists of:
• one six-foot cable
• one terminal block
• one snap track
Note Supporting all of the connections on units with the optional I/O
expansion board requires:
• two DB37 kits
• one DB25 kit
