LG1093AA46 Honeywell Flame Sensor PLC
Functional Architecture
-
Triple-Channel Design
- 3 isolated input channels with independent signal processing chains
- Per-channel operations:
▸ Thermoelectric voltage acquisition
▸ Linearization & cold-junction compensation (CJC)
▸ 16-bit signed integer conversion (LSB = 0.125°C/°F)
-
Data Integrity Assurance
- Mid-value selection algorithm for cross-processor consensus
- Scan-synchronous value validation

a. Later versions of NITC firmware (meta 4873 or greater) freeze inputs for one second upon detection
of hot-spare insertion.
b. If the input readings differ by a minimum of 0.5 percent of full scale and continue for a minimum
period of 256 input samples, the probability of a fault increases.
