The CED1902-11 family comprises optional electrode adaptor
boxes that plug into the electrode input sockets of CED 1902
isolation amplifiers. There are four variants of the smaller box:
• CED1902-11-2 2 channel (bipolar)
• CED1902-11-2B 2 channel (bipolar or common-reference)
• CED1902-11-4 4 channel (bipolar)
• CED1902-11-4B 4 channel (bipolar or common-reference)
CED also manufactures two 16-channel electrode boxes:
• CED1902-11-16 16 channel (common-reference)
• CED1902-11-16B 16 channel (bipolar or common-reference)
The electrode boxes have
input connectors for up to
16 electrode pairs plus
common electrodes. The
connectors can be either
1.5mm or 2mm safety
(touch-proof) types. The
boxes are passive, i.e. they
do not amplify the signals.
The outputs are connected
to the electrode inputs of
CED 1902 isolation
amplifiers via shielded
cables. The boxes have two
or more Common input
connectors that are linked
together and to the
Common leads of all the
output cables. The interior
of the box is coated with
electro-conductive paint
which is electrically
connected to the screens of
the output cables.
