*1 Total current of two outputs should be less than 100 mA.
*2 Only available on certain models.
*3 When using the HIGH SPEED mode, the power consumption increases by 160 mW (7 mA).
*4 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.
