Standard 2-wire transmitter wiring
The HART/non-HART Analog Input IOM/IOTA is optimized for use with classic two-
wire transmitters. All 16 channels can accept inputs from two-wire transmitters. It is
recommended to use channels 13 through 16, since these channels have a dedicated
Series 8 ground screw (although it is possible to use channels 1 through 12).
Following figure illustrates an example jumper configuration for channel 1 of non-
redundant 9 inch IOTA.

Self-powered 3-wire transmitter (system ground)
It is recommended to use channels 13 through 16, since these channels have 3 screws per
channel (although it is possible to use channels 1 through 12).
For the following example:
Channel 13 is used
The three wires are terminated to TB1-25, TB1-26, and TB2-1
