If you want to use 24 VDC from the island’s sensor bus to power the analog field
devices, this power can be delivered through the input module. To do this, use pins
1 and 6 as follows:
1 +24 VDC for sensor 1 (top) and for sensor 2 (bottom)
2 inputs from sensor 1 (top) and sensor 2 (bottom)
4 returns from input 1 (top) and input 2 (bottom)
6 field power return from sensor 1 (top) and sensor 2 (bottom)
Remember that using pins 1 and 6 will defeat the built-in isolation between the
analog portion of the module and the island’s sensor bus.
