Honeywell CC-TDIL01 Programmable Input/Output Unit

Analog Input IOTA Models CC-TAIX01, CC-TAIX11

 The Series C Analog Input IOTA board is represented by the following information and graphic.

 To access the parts information for the:

 • module

 • IOTA

 • terminal plug-in assembly, and

 • fuses

 associated with this board and module, refer to Analog Input in the Recommended Spare Parts section.

 Series C Analog Input 6 inch, non-redundant IOTA is displayed.

 Note: All I/O field terminations accept up to 14 gauge stranded wire.

 To properly wire, your module to the Series C Analog Input IOTA board with terminal block 1 (TB1) and

 terminal block 2 (TB2), use the following tables.

 Field wiring and module protection - Analog Input module

 Individual field wiring is protected by an internal protection circuit permitting:

 • Short circuit protection of input for field short circuits. Protection suitable for Division 2 non-incendive / Zone 2 non-arcing.

 • Each signal can be shorted in the field with no damage to module or board. Other channels on the same IOM will not be affected

Two-wire transmitter wiring - Analog Input module

 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:

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

 • 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.

Sensor Drive Modules

Two sensor drive modules are provided:

a. Sensor Drive Module, 4 - 20mA, Part Number 05701-A-0283

b. Sensor Drive Module Catalytic, Part Number 05701-A-0284

The Sensor Drive Module conditions the incoming catalytic or 4 -20mA sensor signal and provides the necessary sensor power supply.

It contains all the circuitry necessary to generate the voltages and currents required to drive the sensor,

the circuitry to acquire the sensor signal and to scale the sensor signal to a standard output. 

The sensor drive modules are factory fitted and plug directly onto the channel control card.

Analogue Output Module

An optional Analogue Output Module, (Part Number 05701-A-0285),

may be factory fitted to the Single Channel Control Card and is used on a channel of gas detection to provide an isolated current loop output which follows the sensor signal level. 

This may be set electronically to produce a 0 - 20mA output or a 4 - 20mA output and

can be used to operate a chart recorder, etc.
