1. All terminals with the same name are connected together on the module. For example, DC
(+) can be connected to either terminal marked DC-1+. If you are daisy chain wiring from
one of these terminals to other RTBs, only connect wiring to one terminal.
2. When you daisy chain from a group to another RTB, always connect the daisy chain to the
terminal directly connected to the supply wire, as shown above.
3. This wiring example shows a single voltage source.
4. If separate power sources are used, do not exceed the specified isolation voltage.

1. All terminals with the same name are connected together on the module. For example,
DC (+) can be connected to either terminal marked DC-1 (+).
2. Do not physically connect more than two wires to a single RTB terminal. When
jumpering I/O groups together and daisy chain wiring to adjacent modules, follow the
wiring method shown above.
3. This wiring example shows a single voltage source.
4. If separate power sources are used, do not exceed the specified isolation voltage.

This is a general wiring example illustrating Axis 1 wiring only. Other
configurations are possible with Axis 0 wiring identical to Axis 1.
