You wire the 482 digital input/output module on a 40–pin connector using
screw–type or crimp snap–in connections. Because the module has no two–
wire connection, you need to use an external distribution block.
One terminal on the 40–pin connector is assigned to each channel. The chan-
nel numbers are printed on the front panel of the module. The 16 channels of
the input side (IN) and the output side (OUT) of the 482 digital I/O module
are numbered.
