Input Channel Adapter
Each input channel is provided with a mating Input Channel Adaptor (ICA) or
“breakout box”. These inexpensive adaptors simplify the business of integrating
a strain gage subsystem with the Spider-80SG. The adapter mates to the
Spider-80SG through a 14” cable terminated in a LEMO connector. The ICA
provides an eight screw-terminal barrier strip to accept the wires soldered to an
installed strain gage or bridge or partial bridge of strain gages.

The Input Channel Adaptor simplifies “mating” the multiple wires coming from
one, two, or four strain gages to form a single channel input to the Spider-80SG.
The ICA provides simple connection diagrams for all the conventional gage
configurations. Provision to utilize remote sensing leads is provided.
There are no components within the ICA. It serves solely as a convenient conduit
to the Spider-80SG input LEMO connectors. 26 AWG gage leads may be soldered
directly to a 7-pin male connector (LEMO part #FGG.2K.307.CLAC85Z), if
desired.

The following table summarizes the pinout of the LEMO input connector and its
cabled connection to the Input Channel Adaptor.
