ISO1042 sllsF09-osp1042-device-net-iso1211-sn6505.gifFigure 33. ISO1042, ISO1211 and SN6505 Used in a DeviceNet Application

Figure 33 shows an application circuit for using ISO1042, ISO1211 and SN6505 in a DeviceNet application. ISO1042 is used to isolate the CAN interface. The ISO1211 24-V digital input receiver is used to detect the absence or presence of the 24-V field supply. The SN6505 push-pull transformer driver, is used to create an auxiliary isolated power supply for the micro-controller side using the 24-V field supply.
