Analog Input Units Section 7-2
Allocation of I/O Words Expansion Units and Expansion I/O Units are allocated I/O bits in the order
the Units are connected starting from the CPU Unit. When the power to the
CPU Unit is turned ON, the CPU Unit checks for any Expansion Units and
Expansion I/O Units connected to it and automatically allocates I/O bits
7-2 Analog Input Units
Each CP1W-AD041/CPM1A-AD041 Analog Input Unit provides four analog
inputs.
• The analog input signal ranges are 0 to 5 V, 1 to 5 V, 0 to 10 V, -10 to +10
V, 0 to 20 mA, and 4 to 20 mA. The resolution is 1/6,000. The open-circuit
detection function is activated in the ranges of 1 to 5 V and 4 to 20 mA.
• The Analog Input Unit uses four input words and two output words, so a
maximum of three Units can be connected.
