▪ TB2
This terminal block accepts input numbers nine through 16.
▪ TB3
This terminal block accepts input numbers 17 through 24.
▪ TB4
This terminal block accepts input numbers 25 through 32.
Terminal blocks TB1 – TB4 protrude through the rear panel of the M9000 module and are
connected directly to the field status circuits. The board mounting blocks are used to attach
the board to the chassis rear panel and to form the electrical ground connection for the
high-voltage surge suppression capacitors.
Warning: Equipment damage will occur if joints are not mechanically tight. Surge capacitors
must be grounded through mechanical joints between the circuit board mounting
blocks and the chassis rear panel.
