^*1 When several units are connected, the ambient temperature requirement varies depending on the total number of units connected. When 2 to 5 units: -10 to +50 °C 14 to 122 °F When 6 to 7 units: -10 to +45 °C 14 to 113 °F When connecting several units, be sure to mount the units to a metallic DIN rail. Make sure that the output current does not exceed 20 mA.
