If the T-branch Connector is at the end of the trunk line, the trunk line can be terminated by connecting a shielded connector with Terminating Resistance. When the Network is powered by a single communications power supply and the current consumption is within the T-branch Connector's specifications, the communications power supply can be connected to a T-branch 57 Cables, Connectors, and Related Devices Section 2-3 Connector (using a shielded cable with a connector on one end) instead of a Power Supply Tap.

Used together with the DCN4-TR4-1 to extend or branch flat cable. Types of T-branch Connectors DCN4-BR4 DCN4-BR4D Used together with the DCN4-TR4-1 to branch to thin cable. 2-3-7 Power Supply Tap In the DeviceNet system, a 24-V DC communications power supply must be supplied to the Network. The communications power supply can be supplied to the cable by connecting it to a Power Supply Tap. Use a regular node connector to connect communications cable to the Power Supply Tap, the same way that communications cables are connected to a T-branch Tap. Note 1. If there is just one power supply to the Network and the total current consumption is less than 5 A, the communications power supply can be connected through a regular T-branch Tap instead of a Power Supply Tap. A Power Supply Tap must be used if there is more than one power supply connected to the Network or the total current consumption exceeds 5 A. When the Power Supply Tap is connected to thin cable, the current capacity is limited to 3 A through any one of the thin cables.
