2.2.3.4 Safety
Wiring
ELCM-EX DIDO
In an ELC control system, many devices are controlled at the same time and the actions of any
device could influence another, i.e. the breakdown of any device may cause the breakdown of
the entire control system. Therefore, we suggest wiring a protection circuit at the power supply
input. See 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)

Input Wiring
There are 2 types of DC inputs, SINK and SOURCE. (See the examples below. For additional
information, please refer to the specifications for each module.)
