*1 The response speed varies depending on the number of expansion units connected.
*2 Change the supply voltage to meet the requirement of the input device (PLC, etc.).
*3 If more than one unit is used together, the ambient temperature varies with the conditions below. Mount the units on the DIN rail with mounting brackets and check that the output current is 20 mA or less.
1 to 5 Units: -10 to +50 °C, 6 to 8 Units: -10 to +45 °C.
