Analog Input Signal Processing
The 10105/2/1 converts analog voltage signals into digital values through its 12-bit A/D converter. Its 16 input channels support voltage measurements from 0 to 4.1 V, with input resistance greater than 1 MOhm. The specified converter inaccuracy is +/- 1 LSB, while the overall module inaccuracy is less than 0.25%.
The module provides an external voltage readback input with a range of 0 to 4 V. All 16 channels share an isolated analog 0 V common. The supplied documentation identifies the channels as fail-safe and lists AK5 as the channel safety classification; the separate AK1-6 entry requires confirmation against the applicable hardware documentation.
Frequently Asked Questions (FAQ)
Q: How many analog input channels does the Honeywell 10105/2/1 support?
A: It supports 16 analog input channels, each with an input range of 0 to 4.1 V.
Q: What are the A/D conversion resolution and accuracy specifications?
A: The module uses a 12-bit A/D converter with a specified converter inaccuracy of +/- 1 LSB. Overall module inaccuracy is specified as less than 0.25%.
Q: What power supply does the 10105/2/1 require?
A: The specified power requirement is 5 VDC at 35 mA. Confirm the applicable FSC rack and backplane requirements before installation.
Field Installation Guidelines
- Verify the complete model number and hardware revision against the existing FSC Safety Manager system documentation.
- Confirm software compatibility with the installed system; the supplied specification lists software version 500 or higher.
- Check the module position and available rack space against the specified 4 TE and 3 HE requirements.
- Verify the 5 VDC supply and current capacity before connecting the module.
- Confirm analog input polarity, signal common, and external voltage readback wiring against the manufacturer’s terminal diagram.
- Route low-level analog signal wiring separately from power and high-current switching conductors to reduce electrical interference.
- Apply shield grounding according to the system grounding design and manufacturer instructions.
- Because the manufacturer has discontinued the module, verify hardware revision, compatibility, and safety-system approval before using a replacement or refurbished unit.
