          *1 To connect several units they must be mounted on a METAL DIN rail. Ensure that the output current is 20 mA max. With several units connected, the allowable ambient temperature range varies as follows :
          When 2 to 5 expansion units are additionally installed : -10 to +50ºC (14 to 122ºF).
          When 6 or 7 expansion units are additionally installed : -10 to +45ºC (14 to 113ºF).
          *2 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.
