3-2-4 I/O Specifications for Expansion I/O Units
This section describes the I/O specifications common to all Expansion I/O Units.
z Input Specifications
(CP1W-8ED/20EDR1/20EDT/20EDT1/40EDR/40EDT/40EDT1)
* The response time is the delay caused by hardware. The delay set in the PLC Setup (0 to 32 ms, default: 8 ms)
must be added to this value. For the CP1W-40EDR/EDT/EDT1, a fixed value of 16 ms must be added.
Precautions for Safe Use
Do not apply voltage in excess of the rated voltage to the input terminal.
