5.3.2 Handling of 5V DC Input
1. Input terminals
When an input terminal and the 5+ terminal are
connected with the 5V DC circuit (shown in the
figure on the right), the input turns ON. At this time,
the input indicator LED turns ON.
Multiple 5+ terminals are connected inside the PLC.
2. Input circuit
The primary and secondary circuits for input are
insulated with a photocoupler. Response delay of
approximately 1ms is given for a change in the input
