Transistor Input Units
Section 4-3
Wiring Examples
Note V terminals and V connector pins, as well as G terminals and G connector
pins, are internally connected. When the I/O power is being supplied from a
terminal block, the power can be supplied to the input devices from the V and
G connectors. Current supplied in this way, however, must be less than 1 A.
Dimensions
Note The vertical center of the Unit is 4.9 mm lower than the center of the DIN
track. The Unit therefore extends downward 41.4 mm (including the mounting
hook) from the DIN track center.
