1.  When using controllers with fewer than 32 points, the first expansion 

input address will start at X20. The first expansion output address will 
start at Y20. Please refer to the following example for more details:

The 1

st

 digital I/O module ELCM-EX08NNDR only has 4 inputs and 4 

outputs but is addressed as an 8 input / 8 output module. The highest 
4 input addresses and highest 4 output addresses have no physical 
I/O points associated with them. For the 2

nd

 digital I/O module 

ELCM-EX16NNDR, the input points start from X30, and output points 
start from Y30. 

 

Output current supplied from 24VDC on the controller is 500mA(12W). 
Remaining applicable power: 12 - (1.2 + 2.4 + 2.4) = 6W 

 Power Supply 

Please note the following when using ELCM-EX Digital Input and Digital 
Output (DIDO) with the ELCM-PH/PA series controllers: 

1.  The AC power supply voltage range for ELCM-PH/PA series controllers 

is 100 ~ 240VAC. Please connect the AC power supply to L and N 
terminals and note that connecting 110VAC or 220VAC to +24V output 
terminals or digital input terminals will damage the ELCM or its 
expansion I/O. 

2.  The power supply for digital I/O points is 24VDC. Please make sure the 

power supply polarity is correctly connected. 

3.  It is highly suggested that the DC power supplies for the controllers and 

ELCM-EX DIDO switch ON and OFF at the same time. 

4.  Use 1.6mm wire (or larger) for grounding. 

5.  A power loss of less than 10ms will not affect the operation of the ELCM. 

However, a power loss that is too long, or a sustained drop of power 
supply voltage will stop the running of the ELCM. All outputs will turn 
“OFF”. When proper power is restored, the ELCM will resume normal 
operation. (Please keep this in mind when you use latched auxiliary 
relays and registers in your ELCM program.) 

 Safety Wiring 

In ELCM control systems, many devices are controlled at the same time
