*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).
