Wiring Examples
This section shows examples of wiring of parts such as an emergency stop switch and start/stop/reset switch.
Double wiring (using test pulse outputs)
With two input modules with diagnostic functions, an emergency stop switch is wired as follows:
■
Input double wiring
Apply input double wiring in either of the following combinations.
• For the RX40NC6B (Main) and the RX40NC6B (Sub), wire even-numbered input terminals with T0 test pulse output
terminals.
• For the RX40NC6B (Main) and the RX40NC6B (Sub), wire odd-numbered input terminals with T1 test pulse output
terminals.
(1) Connect an emergency stop switch that has two normally closed contacts based on direct opening action, between X00 to X0F (input) terminals and T0 and
T1 (test pulse output) terminals.
