10.3 100V AC Input
10.3.1 Input specifications
Main units of a 100V AC input type are not available.
Select the input for the input/output powered extension units/blocks.
→ For the specifications on input/output powered extension units, refer to Chapter 15.
→ For the specifications on input/output extension blocks, refer to Chapter 16.
10.3.2 Handling of 100V AC Input
1. Input terminal
When voltage of 100 to 120V AC is applied between the input
terminal and COM terminal, the input terminal is turned on. The
input display LED lights.
Do not connect the COM terminal of an AC input type input/
output powered extension unit/block with the COM terminal of a
DC system.
2. Input circuit
The primary input circuit and the secondary input circuit are
insulated with a photocoupler.
There is a delay of approx. 25 to 30ms in response to input
switching from ON to OFF and from OFF to ON.
3. Input sensitivity
The input current and input sensitivity of these PLCs are shown in the following table.
