5.4.1 AC input specifications
The table below shows the input specifications of the FX2N-8EX-UA1/UL and FX0N-8EX-UA1/UL.
5.4.2 Handling of 100V AC Input
1. Input terminals
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
extension blocks 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.
Response delay of approximately 25ms to 30ms is given
for a change in the input ("ON
→ OFF" or "OFF → ON").
3. Input sensitivity
The input current and input sensitivity of these PLCs are
shown in the following table.
