Honeywell CC-TAID01

Technical Specifications​

Part number: 51308353-175 for common CC-TAID01 listings

IOTA type: analog input termination assembly

Size: 9 in-class Series C IOTA

Channels: 16 high-level analog input terminations, 12 single-ended and 4 differential configuration support per plugged module

Supported signals: 4-20 mA via 250 Ω, 0-20 mA via 250 Ω, 0-5 V, 1-5 V, 0.4-2 V

Field power: non-incendive current-limited transmitter power for Class 1, Division 2 applications

Wire size: screw terminals accept field conductors per Honeywell IOTA specification, commonly 12-22 AWG

Operating temperature: 0°C to 60°C

Coating: conformal-coated PCB options for humid and corrosive environments

Redundancy: simplex, non-redundant

Functional Features​

Removable screw terminals for organized field wiring. 250 Ω jumper selection for current or voltage operation. Individual channel current limiting. Shield termination provisions. Hot module replacement without rewiring when used with supported carriers.

Application Scenarios​

Simplex pressure, temperature, flow and level analog inputs. General process units where redundant analog input hardware is not required. Retrofit and expansion of Experion PKS C300 analog I/O cabinets.

Performance Parameters​

Termination accuracy depends on the plugged CC-PAIX01/02 module; the IOTA contributes jumper resistance, wiring resistance and shielding quality. Use 250 Ω only for current loops unless the engineering design specifies otherwise.

Material Composition​

FR4 termination PCB, conformal coating option, tinned or plated screw terminals, metal mounting hardware and insulated barrier between field and backplane sides.

Structural Characteristics​

Vertical Series C IOTA with front screw terminals, rear module connector and jumper fields. Field side contains transmitter power terminals, signal terminals and shield grounds; rear side engages the analog input module.

Working Principle​

Field transmitters connect to IOTA terminals. Current inputs pass through 250 Ω precision resistors to produce voltage for the ADC module; voltage inputs connect directly when current jumpers are removed. The IOTA distributes non-incendive loop power, routes conditioned signals to the plug-in module and returns diagnostic status to the controller.

Installation Requirements​

Mount CC-TAID01 in the Series C carrier position assigned to analog input. Install CC-PAIX01 or CC-PAIX02 into the IOTA. Set 250 Ω jumpers for 4-20 mA or 0-20 mA channels and remove them for voltage channels. Connect 2-wire transmitters to loop-power terminals and self-powered transmitters to floating input terminals. Ground cable shields at the IOTA shield bar.

Usage Precautions​

De-energize loop power and backplane before wiring or module replacement. Do not use CC-TAID01 for redundant analog input pairs; use CC-TAID11. Verify non-incendive power ratings before connecting in Division 2 areas. Avoid common-mode voltages outside the plugged module specification. Confirm jumper configuration before applying voltage inputs because incorrect 250 Ω jumpers will overload or short voltage sources.
