(Part number 97739201)
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. If separate power sources are used, do not exceed the specified isolation voltage.
4. Do not connect more than 2 wires to any single terminal.
5. The jumper bar is part number 97739201; use this number to order additional bars.

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-1.
2. When you daisy chain to other RTBs, always connect the daisy chain as shown above. Do not
connect more than 2 wires to any single terminal at any time.
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 COM can be connected to any terminal marked GND-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 above.
3. This wiring example shows a single voltage source.
4. If separate power sources are used, do not exceed the specified isolation voltage.
