Overview
The 8C-TAIM01 Low Level Analog Temperature Input (LLMUX IOP module) manages up to 64 temperature channels. It integrates with Honeywell’s PMIO LLMUX FTA, each FTA supporting 16 channels. Users can mix RTD, Thermocouple (TC), and millivolt (mV) inputs. This module provides precise temperature measurement and seamless Honeywell system integration.
Key Features
- Flexible Temperature Sensing: Supports thermocouples and RTDs for industrial applications.
- Remote Cold Junction Compensation (CJC): Ensures readings remain accurate at connection points.
- Open Thermocouple Detection (OTD): Protects against errors caused by open thermocouples.
- 1-Second PV Scanning: Measures all channels every second without delaying system response.
- Expandable Channels: Add temperature points in increments of 16 for scalable design.
Temperature Support
The LLMUX system collects data from all temperature points every second. Solid-state PMIO LLMUX FTA modules handle both RTD and Thermocouple (TC) inputs. Open thermocouples set the process variable (PV) to NaN, preventing control errors and maintaining system reliability.
Sampling and Open Sensor Detection
The module verifies sensor integrity before PV propagation. With OTD active, PV is sampled and analyzed within the same measurement window. Detected faults set PV to NaN and trigger soft failures. This mechanism avoids invalid readings while maintaining measurement speed.
