1. All terminals with the same name are connected together on the module. For
example, L2 can be connected to either terminal marked L2-15.
2. When you use the second L2-15 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.

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. 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 s ingle voltage source.
4. If separate power sources are used, do n ot exceed the specified isolation voltage.

1. For 2-wire resistor applications, including calibration, make sure IN-x/B and
RTN-x/C are shorted together. The example above shows IN-4/B and RTN-4/C
shorted together.
