Analog Input wiring

Field wiring and module protection
Individual field wiring is protected by an internal protection circuit permitting the
following:

Each signal can be shorted in the field with no damage to the module or board. Other
channels on the same IOM are not affected.
Two-wire transmitter wiring
The Analog Input IOM/IOTA is optimized for use with classic two-wire transmitters. All
16 channels can accept inputs from two-wire transmitters without any special wiring or
jumper options.
