•Wiring example of EX250 and EX500-Q
02 (Drawing shows the EX250)
1: This cable is a bypass cable used for the layout where the Power block is located to the right of the SI unit.
2: The cable and the Power block allow the current up to 3.1 A.
When maximum supply current is 3.0 to 3.1 A, keep the ambient temperature at 40
o
C or less and do not bundle the cable.
Before using the Power block power supply connector (No.0), make sure that the inequality below is satisfied.
Total Output block current consumption (20 mA / point) + Total output load current consu Total valve manifold current
consumption = 3.1 A.
If a current of more than 3.1 A can not be avoided, supply the power to the Power block and SI unit (solenoid valve manifold) by
separate cables.
