*1 S-APC will be always turned ON when the high-resolution or high-speed mode is selected. S-APC is by default set to OFF in any other mode.
*2 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.
3 to 10 Units: –10 to +50 °C 14 to 122 °) 11 to 16 Units: –10 to +45 °C 14 to 113 °F
