2. DO NOT wire empty terminals. DO NOT place the input signal wire and output power wire in
the same wiring circuit.
3. DO NOT drop tiny metallic conductors into the ELC during installation..
z
Attach the dustproof sticker to the ELC before the installation to prevent conductive objects
from dropping in.
z
Tear off the sticker before running the ELC to ensure normal heat dissipation.
1.4.3.3 Power
Supply
The power input type for ELCB-PB model is AC. When operating ELCB-PB, please note the
following points:
1. The range of the input voltage should be 100 ~ 240VAC. The power supply should be
connected to L and N terminals. Please note that wiring 110V AC or 220V AC to +24V output
terminals or digital input points will result in serious damage on the ELC.
2. The AC power inputs for the controller and the digital I/O module power should be ON or OFF
at the same time.
3. Use 1.6mm wire for the grounding of the ELC.
4. A power dip of less than 10ms will not affect the operation of the ELC.
5. The +24V output is rated at 0.5A from the controller. DO NOT connect other external power
supplies to this terminal. Each input terminal 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.
1.4.3.4 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.
