Input Specifications of Expansion I/O Units
DC Inputs
(CP1W-40EDR/40EDT/40EDT1/20EDR1/20EDT/20EDT1/8ED)
Note 1. Do not apply a voltage exceeding the rated voltage to an input terminal.
2. Can be set in the PLC Setup to 0, 0.5, 1, 2, 4, 8, 16 or 32 ms.
The CP1W-40EDR/EDT/EDT1 are fixed at 16 ms.
Relay Outputs
(CP1W-40EDR/20EDR1/16ER/8ER)
Note: Under tahe worst conditions, the service life of output contacts is as shown
on the left. The service life of relays is as shown in the following diagram
as a guideline.
Transistor Outputs (Sinking/Sourcing)
Note 1. Do not apply a voltage or connect a load to an output terminal exceeding
the maximum switching capacity.
2. The fuses cannot be replaced by the user.
3. A maximum of 0.9 A per common can be switched at an ambient
temperature of 50C.
