If you want to use 24 VDC from the island’s field power bus for the single-ended
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)
3 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 defeats the built-in isolation between the analog
portion of the module and the island’s field power bus.
