TK-PRS021 Honeywell Input module Brand new

The AI 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.

The standard usage is to:

l reserve the first 12 channels of the AI IOM/IOTA for classic two-wire transmitters, and

l use the last 4 channels of the IOM/IOTA to interface any of the supported input styles

(including two-wire transmitters).

Depending on the input style applied to channels 13 through 16, you may need to cut jumpers on

the IOTA and apply wiring to the TB2 terminal block on the IOTA. This is discussed in detail in the

following sections.

5.1.3 Non two-wire transmitter wiring - Analog Input module

The IOTA is pre-engineered (without custom wiring) to accept sources that are not two-wire

transmitters, but you must use channels 13 through 16.

When sources other than two-wire transmitters are to be interfaced and you have more than 4 per

IOTAs, then:

l the first four must be interfaced to channels 13 through 16, and

l the remainder may be able to interface to channels 1 through 12 (depending on input style)

but you must perform some degree of custom wiring.

NOTE

There are some input styles that simply cannot be applied to channels 1 through 12 - if that

applies to you then you will likely need to purchase an additional IOM/IOTA.

CAUTION

The jumpers on the IOTA are non-repairable; once cut, they stay cut. Careful planning is a
