FAQs

Q1: What is the primary function of the Honeywell 10105/2/1?

The 10105/2/1 is a fail-safe high-density analog input module for the Honeywell FSC system. It acquires up to 16 analog field signals (after conversion to 0–4.1 V DC) and converts them to digital data for safety-critical monitoring and interlocking calculations in process control systems.

Q2: What is the safety class of this module?

The module meets safety class AK1–6 per the FSC system standard, achieving AK6 in redundant mode. It is also certified for SIL 2/3 applications, making it suitable for the highest safety integrity level requirements in process industries.

Q3: How do I connect standard 4–20 mA transmitters to this module?

The module's native input range is 0–4.1 V DC and requires external conversion for current-loop signals. This can be done using either the FTA-T-14 field termination assembly or the 10105/A/1 analog input conversion module placed on the I/O backplane programming connector.

Q4: What self-diagnostic features does the 10105/2/1 include?

The module performs comprehensive self-tests controlled by the FSC system CPU, including: absolute accuracy checks, full-range conversion verification, crosstalk between inputs, channel input filter verification, and internal supply voltage monitoring.

Q5: What is the maximum input voltage the module can withstand?

The module can withstand an absolute maximum input signal of ±36 V DC without damage, providing robust protection against transient surges in industrial environments.
