Honeywell MC-TAIH02 High Level Analog Input/STI FTA (16 Inputs)

Honeywell MC-TAIH02 High Level Analog Input/STI FTA (16 Inputs)

Functional Description

High and low level analog input (HLAI + LLAI - 8) processors both perform signal conversion and conditioning functions:

• PV Source (Auto, Manual, Substituted)

• PV Clamping

• EU Conversion

• PV Value Status

• PV Filter (Single Lag)

• Bad PV

• PV Hi/Lo

• PV HiHi/LoLo

• PV Rate-of-Change +/-

• Software Calibration

• Low PV Cutoff

They perform engineering unit conversion, including fifth-order polynomial temperature input characterization, if the high level processor receives these inputs from mV/I converters. Through use of a dual processor design and custom integrated circuits, the low level analog input processor supports software configuration per channel for different thermocouples or RTD types with excellent resolution and accuracy. Open thermocouple detection is performed once per scan so that no bad data is propagated for control processing.
