Product Overview

The Honeywell CC-TAIN11 (PN: 51308388-175) is a 16-channel Redundant Analog Input IOTA for the Experion PKS Series C platform. It provides physical mounting and wiring for a redundant pair of CC-PAIN01 Analog Input modules, ensuring uninterrupted real-time process data even if one module fails.

This 12-inch vertical IOTA is the standard interface for critical 4–20 mA process measurements and supports both 2-wire (loop-powered) and 4-wire transmitters. The G3 conformal coating (-175) protects the board against humidity, chemical vapors, and corrosion.

Technical Data

Key Features:

• Bumpless Redundancy: Primary and secondary AI modules synchronize automatically for uninterrupted operation.

• Flexible Transmitter Powering: Supports 2-wire or 4-wire field devices via internal 24 V DC bus.

• Industrial Hardening: G3 coating prevents corrosion and “silver whiskers” in harsh environments.

• Simplified Troubleshooting: Dedicated test points on each channel allow current measurement without disconnecting wiring.

Typical Applications

• Refinery Pressure Monitoring: Redundant measurement of distillation column pressure to avoid emergency shutdowns.

• Chemical Feed Control: Flow meter monitoring for precise ingredient ratio control.

• Power Plant Water/Steam Loops: Drum level and steam pressure tracking with redundancy for safety.

• Offshore Oil Production: Subsea sensor integration in corrosive marine environments.

FAQ

Q1: Can this IOTA be used with HART transmitters?
A1: CC-TAIN11 supports 4–20 mA from HART transmitters but does not pass HART digital signals. For HART diagnostics, use CC-TAIH11 IOTA and CC-PAIH01 module.

Q2: Difference between CC-TAIN01 and CC-TAIN11?
A2: CC-TAIN01 is a 6-inch non-redundant IOTA holding one module. CC-TAIN11 is 12-inch, redundant, and supports a primary/secondary module pair.

Q3: Can this IOTA handle 1–5 V signals?
A3: Standard Series C AI modules are current-based. To use 1–5 V, add a precision 250 Ω resistor across the input to convert voltage to 4–20 mA.

Q4: Is "Hot-Swap" possible?
A4: Yes. You can replace a failed module in the redundant pair while the system is running; the remaining module continues operation until synchronization is complete.
