The nominal input voltage of this controller is 24V DC and its input voltage ranges from 18-32V DC. Continuous isolation voltage is 30V, which is of a basic insulation type. This isolation has been type-tested at 707V DC for 60 seconds and is from power to enclosure, non-redundant Ethernet channels to non-redundant Ethernet channels, and Ethernet channels to power, but there is no isolation between redundant Ethernet channels. This controller has a non-replaceable fuse that has been soldered into place to guard against fire hazards due to short circuit conditions.
The 1756-L72EROMS’s operating temperature is 0-60 ËšC and its storage temperature is -40-85 ËšC. It also has a maximum ambient temperature of 60 ËšC and a relative humidity of 5-95% non-condensing. This controller’s operating vibration is 2 g at 10-500 Hz, its operating shock is 30 g, and its non-operating shock is 30 g.
