DI-75B Rear Panel
Removable Screw Terminal Block — Allows signal connections to be made to the DI-75B. The input signal con-
nections are made along the top row while the excitation connections (for those DI-5B modules that require excita-
tion) are made along the bottom row. Note that this screw terminal block can be removed from the DI-75B, thus
making signal connections to the screw terminals easy. Note also that the screw terminal block is “keyed,” thus diffi-
cult to improperly re-insert. Each channel (labeled “CHANNEL 1,” “CHANNEL 2,” etc. on the socketed backplane)
has four corresponding screw terminals for your signal connections: c, channel -, exci, and excitation
-. These terminals satisfy all transducer inputs and provide sensor excitation when necessary.
