TK-IAH061
Product Identification
TK-IAH061 is a high-performance 6-channel high-level analog input module from Honeywell's Experion PKS C200 I/O family. It provides precision signal acquisition for voltage (0-10.5 V) and current (4-20 mA) field instruments, converting analog signals into high-resolution digital data for process monitoring and control .
The "TK" prefix designates a conformal coated module, providing enhanced protection against moisture, dust, and corrosive airborne contaminants. This makes it particularly suitable for harsh industrial environments such as chemical plants, paper mills, and offshore platforms. The non-coated equivalent is the TC-IAH061 .
The module features 6 galvanically isolated channels with 16-bit resolution, a 25 ms module update rate, and support for open-circuit detection. It is physically and functionally compatible with the TC-IAH061, using the same TC-TBNH 20-position terminal block .

Functions
Signal acquisition & processing
- High-level analog input — Captures voltage (±10.5 V) and current (4-20 mA) signals from field transmitters and sensors, converting them to digital values for process monitoring and control .
- 16-bit resolution — Provides precise signal discretization across multiple input ranges, with typical resolution of 343 μV for ±10.5V range and 0.34 μA for current loops .
- Galvanic isolation — Channel-to-channel isolation tested at 2546 VDC ensures signal integrity and protects the system from ground loops and electrical interference .
Diagnostics & protection
- Open-circuit detection — Monitors field loop integrity: voltage inputs flag upscale reading (5 sec), current inputs flag zero scale reading (1 sec) .
- RFI immunity — Error of less than 2.0% of range at 10 V/m, 27-1000 MHz, ensuring stable operation in electrically noisy environments .
- Overvoltage protection — Supports 120 VAC/VDC continuous (voltage mode) at room temperature .
Applications
The TK-IAH061 is widely deployed in process control applications requiring precision analog signal acquisition with galvanic isolation and corrosion protection.
Lifecycle
Active currently in production — fully supported
Product status: The TK-IAH061 remains an active, supported product in Honeywell's C200 I/O portfolio. It continues to be the recommended analog input solution for new Experion PKS installations requiring conformal coating.
Spare parts & support: Replacement units and accessories are available through Honeywell's standard support channels and authorized distributors. The C200 I/O family is designed for long‑term availability.
Migration & replacement:
- Conformal coating for corrosive environment protection
- 6 galvanically isolated channels
- 16-bit resolution with 0.1% accuracy
- Open-circuit detection and overvoltage protection
Recommendation: For new Experion PKS analog input applications in harsh environments, the TK-IAH061 remains the recommended solution.
