Honeywell 10105/2/1 Analog Input Module

Basic Product Identity: 

■Product Type: Fail-safe high-density analog input module.

■Core Purpose: Used in industrial safety control systems to collect analog signals, with fail-safe 

performance to ensure safe operation even in component failure scenarios.

Product Identification:

■Type Number: 10105/2/1 (suffix code: 16900).

■Safety Class: AK1-6 (AK6 in redundant mode).

■Software Compatibility: Compatible with FSC software versions ≥ 500.

Core Functional Specifications:

■Input Channels: 16 analog input channels + 1 external voltage readback input.

■Input Range: 0–4.1 V (field signals need conversion to 0(4)-20 mA first, then to 0–4.1 V via FTA-T-

14 or 10105/A/1 converter).

■Signal Compatibility: Thermocouple, PT-100 and other signals require conversion to 0(4)-20 mA 

via dedicated converters before use.

■Self-test Functions: Includes absolute accuracy, full-range conversion correctness, inter-channel 

crosstalk, channel input filters, and internal power supply testing.

■Isolation Feature: Isolated analog 0 V common to all 16 channels, with galvanic isolation between \

5 Vdc circuitry and output circuitry.

Electrical Specifications:

■Input Resistance: > 1 MOhm (analog input channels); typically 1 MOhm (external voltage 

readback).

■A/D Converter: 12-bit, with converter inaccuracy ± 1 LSB and module inaccuracy < 0.25%.

■Absolute Maximum Input Signal: ± 36 Vdc.

■Crosstalk: > 60 dB (a step response on one channel does not affect other channels beyond 2 LSBs).

■Power Requirements: 5 Vdc (35 mA), 24 Vdc (35 mA).

■Readback Function: External voltage readback range 0–4.1 V, supporting power supply monitoring.

Installation & Usage Notes：

■Signal Conversion Requirement: Field signals must be converted to 0(4)-20 mA first, then to 0–4.1 

V via FTA-T-14 (field termination assembly) or 10105/A/1 (analog input converter module).

■Wiring: Connected to FTA or converter modules via system cables; analog ground and power 

supply lines need proper isolation to avoid interference.

■Replacement: Can be hot-swapped (power on during replacement), but process operation may be 

affected depending on signal function and system configuration; disconnect the horizontal bus 

flatcable before removal.

Mechanical & Compatibility:

■Space Requirements: 4 TE (20.32 mm) width, 3 HE (3U) height, suitable for standard 19-inch I/O 

racks.

■Mounting: Installed in FSC system I/O racks, address determined by rack position (no jumpers for 

address setting).

■Compatibility: Works with FTA (Field Termination Assembly) modules and 10105/A/1 analog input 

converter modules; replaceable with same-type modules.
