1. All terminals with the same name are connected together on the module. For example,
L2 can be connected to any terminal marked L2-0.
2. This wiring example shows a single voltage source.
3. When you daisy chain from a group to other RTBs, alway connect the daisy chain to the
terminal directly connected to the supply wire, as shown above.
4. If separate power sources are used, do not exceed the specified isolation voltage.
Resistors are not necessary if Wire Off diagnostic
is not used.

1. All terminals with the same name are connected together on the module. For
example, DC COM can be connected to either terminal marked GND-0.
2. 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.
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 GND-15.
2. When you use the second GND-15 terminal to 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.
3. Each input 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 voltage.
