10 Input Wiring Procedures (Input Interruption and Pulse Catch)
10.3 100V AC Input Type
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 is lit.
Do not connect the COM terminal of an AC input type main
unit and 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.
4. Cautions on use
The response time of the AC input type is slower than that of the DC input type.
The applications shown below are not supported.
