connected to L and N terminals. Please note that wiring 110V AC or 220V AC to +24V output
terminal or digital input points will result in serious damage to the ELC.
2. The AC power for the controller and for the digital I/O modules should be turned ON and OFF
at the same time.
3. Use 1.6mm wire for grounding of the ELC.
4. The power shutdown of less than 10ms will not affect the operation of the ELC.
5. The +24VDC output voltage is rated at 0.5A from the controller. DO NOT connect other
external power supplies to this terminal. Each input draws 5 ~ 7mA. A 16-point input module
will require approximately 100mA. Therefore, the +24V output power cannot provide power for
an external load that is more than 400mA.
1.3.4.4 Safety
Wiring
In an ELC control system, many devices are controlled at the same time and actions of any device
could influence another. Therefore, we suggest you wire a protection circuit at the power supply
input terminals, per the figure below.
1. AC power supply:100 ~ 240VAC, 50/60Hz
2. Breaker
3. Emergency stop
4. Power indicator
5. AC power supply load
6. Power supply circuit protection fuse (2A)
7. ELC (main processing unit)
8. DC power supply output: 24VDC, 500mA
9. Grounding resistance: < 100
Ω
10.
DC power supply: 24VDC
11. Digital I/O module (DC supply)
12. Digital I/O module (AC supply)
13. Analog I/O module (DC supply)
