Chapter 4 Installation and Wiring Safety wiring: The PLC controls many devices, and the activity of any device affects the activity of other devices. If any device breaks down, the whole automatic control system goes out of control, and the danger occurs. The protection circuit is shown below. 24VDC 100~240VAC 50/60Hz MC 2A 4_ 24VDC 2A 4-21 VS+ VS- PS05 L N CPU UP ZP DI/DO ｍodule UP ZP UP ZP AI/AO ｍodule VS+ VS- UP ZP VS+ VS- PS05 L N UP ZP AI/AO ｍodule Network ｍodule Motion ｍodule VS+ VS- ① Alternating-current power supply: 100~240 VAC, and 50/60 Hz ② Circuit breaker ③ Emergency stop: The emergency stop button can be used to cut off the power when an emergency occurs.
