Daisy chain
to other
RTBs
1. When you daisy chain from a group to another RTB, always connect the daisy
chain as shown above. Do not connect more than 2 wires to any single terminal.
2. This wiring example uses a single voltage source.
3. 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-15.
2. When you use the second DC-15 (+) terminal to daisy chain to other RTBs, always
connect the daisy chain as shown in the example above. Do not connect more than
2 wires to any single terminal.
3. Outputs can be wired in a sink or source configuration as shown above.
4. If separate power sources are used, do not exceed the specified isolation voltages.

Daisy chain to other RTBs
1. All terminals with the same name are connected on the module. For example, DC
COM can be connected to either terminal marked RTN OUT-1.
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.
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,
the load can be connected to either terminal marked OUT-0.
2. When you daisy chain to other RTBs, always connect the daisy chain to the terminal
directly connected to the supply wire, as shown in the example above.
