Setting Input Mode (Voltage/Current)
Chapter 6.
6.1 Setting Voltage Input Mode
To use Ezi-IO EtherCAT AD in Voltage Input Mode, select either SDO communication or DIP switch setting
method for setting input voltage range.
Setting Voltage Input Mode through SDO Communication 6.1.1
In Voltage Input Mode, set DIP switches as the Figure 6-1 for setting input voltage range using SDO
communication.
(Example) Setting Channel 2
① Set LSET switch (SW3.1) of INPUT RANGE to OFF before supplying power to the module.
② Set Channel 2 to Voltage Input Mode with the Input Mode Selection Switch (SW4.2=OFF) before
supplying power to the module.
③ Connect the analog input signal and ground to the pin 2 and GND of Input Connector (CN2).

Setting Voltage Input Mode with DIP Switches 6.1.2
In Voltage Input Mode, set DIP switches as the Figure 6-2 for setting input voltage range using DIP switches.
(Example) Setting Channel 2 to -5~5V Input Range
① Set LSET switch (SW3.1) of INPUT RANGE to ON before supplying power to the module. Set the voltage
input range of Channel 2 with SW3.3~SW3.4 switches.
② Set Channel 2 to Voltage Input Mode with the Input Mode Selection Switch (SW4.2=OFF) before
supplying power to the module.
③ Connect the analog input signal and ground to the pin 2 and GND of Input Connector (CN2).
