4) The following diagram shows an example of terminal connections.
Note: (1) Isolation between Input Channels
There is no insolation provided between the input circuit channels. If isolation
between channels is required, use a commercial isolation amplifier for each
channel.
(2) Recommended Cables
Use shielded twisted-pair wires 1.3 mm 2 (AWG16) to 0.5 mm 2 (AWG20) to con-
nect to the terminal block.
