in depth DIN rail. When mounting the ELC to 35mm DIN rail, be sure to use the retaining clip to
stop any side-to-side movement of the ELC and reduce the chance of wires coming loose. The
retaining clip is at the bottom of the ELC. To secure the ELC to DIN rail, pull the clip down,
place it onto the rail and push the clip back up. To remove the ELC, pull the retaining clip down
with a flat screwdriver and remove the ELC from the DIN rail.

Direct Mounting:
Use M4 screws for direct mounting of the product.
2.2.3.2 Terminal
Torque
1. Use the 12-24 AWG single-core wire or the multi-core wire for the I/O wiring. The ELC terminal
screws should be tightened to 3.80 kg-cm (3.30 in-lbs) and please use 60/75°C copper
conductor only.
24-12AWG
< 1.5mm
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 conductor into the ELC during installation..
z
Please 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.
2.2.3.3 Power
Supply
ELCM-EX DIDO
ELCM-EX DIDO work with ELCM-PH/PA series controllers. Please note the following:
1. The AC power supply voltage range for ELCM-PH/PA controllers is 100 ~ 240VAC.
Connect the AC power supply to L and N terminals and note that connecting 110VAC or
220VAC to +24VDC output terminals or digital input terminals will damage the ELC.
2. The power supply for digital I/O points is 24VDC. Please make sure the 24VDC power
supply is correctly connected.
3. It is highly suggested that the power sources for the controller and ELCM digital I/O
modules is applied and removed at the same time.
4. Use 1.6mm wire for the grounding of the ELC.
A loss of power for less than 10ms will not affect the operation of the ELC. However, a loss of
power that is longer than 10ms or will stop the ELC, and all outputs will be turned “OFF”. When
the power supply returns to normal again, the ELC will automatically return to its operation.
