CP1E CPU Unit Hardware User’s Manual(W479)
A total of up to three of the following Expansion I/O Units can be connected to a CPU Unit with 30 or 40
I/O points. (The total of three Units must also include Expansion Units.)
24-input/16-output Unit, 32-output Unit, 12-input/8-output Unit, 16-output Unit, 8-input Unit, or 8-out-
put Unit
With a CPU Unit with 30 or 40 I/O points, a total of up to three of the following Expansion Units can be
connected. (The total of three Units must also include Expansion I/O Units.)
Analog I/O Unit, Analog Input Unit, Analog Output Unit, Temperature Sensor Units, CompoBus/S I/O
Link Unit
By setting a built-in input to quick-response input operation, inputs with signal widths as small as 50 µs
can be read with certainty regardless of the cycle time.
Up to six quick-response inputs can be used.
Note The user setting in the PLC Setup determines if each input is a quick-response input, normal input, interrupt
input, or high-speed counter input.
With CPU Units with 30 or 40 I/O Points, Add I/O by Connecting
