Figure 6 - Pin Connections for the Aux Power Connectors
The power for the output port is separate from the power to the remaining
portions of the interface block. This configuration allows the output device to
be turned off, while maintaining power to the transceivers, the input port, and
the EtherNet/IP™ connection. When the output is connected to the
safety-related portion of the machine control system, an actuator can be
turned off, while diagnostic information is still available to the machine
control system.
Power Connection Options Each interface block is limited to 4 A total consumption.
Example 1: Daisy Chain the Power Connections
The example in Figure 7 allows for a simple and easy way to distribute power to
the RFID system. This approach is preferred when the total current of the
RFID system is less than 4 A.
Figure 7 - Power Option 1
Example 2: System Needs More Than 4 A
If multiple blocks are required on a machine and the current consumption
exceeds 4 A, then a combination of mini-style and micro-style connections can
be used to distribute the power. In the example shown in Figure 8 on page 29
,
mini-style cordsets, patchcords, and tees are used to configure the power. A
mini-to-micro style patchcord connects each 56RF interface block with the tee.
In this example, the power supply is a catalog number 1606-XLDNET8, which
can supply up to 8 A to the RFID system.
