HollySys K-AI01 8-Channel Analog Input Module
HOLLiAS MACS-K eight-channel current-input module with optional redundancy.
Product Identification
HollySys K-AI01 is an eight-channel current-input module in the HOLLiAS MACS-K distributed control system family.
It acquires standard current signals from process transmitters and presents the configured values and status to the MACS-K controller. Optional redundancy is available when the approved base and system architecture are used.
K-AI01 is the standard current-input model; applications requiring HART communication should use the specifically engineered K-AIH01 arrangement.

Functions
Acquires eight process-current signals.
Converts field inputs for use by MACS-K control strategies and operator displays.
Supports approved two-wire and four-wire transmitter circuits.
Can operate in an optional redundant module arrangement.
Reports module and channel state to support commissioning and maintenance.
Integrates through the MACS-K base and I/O-BUS architecture.
System Integration
Match K-AI01 to the approved base and terminal board.
Confirm transmitter type, loop power, polarity, shield grounding and cabinet common arrangement.
Configure range, scaling, engineering units, filtering and alarm behavior for each channel.
For redundancy, install and configure the complete approved redundant base and module pair.
Verify the module revision and MACS-K software compatibility before loading configuration.
Applications
Pressure, flow, level and temperature transmitter inputs.
Eight-channel 4–20 mA process acquisition.
General analog monitoring in MACS-K control stations.
Optional redundant analog-input service.
Like-for-like replacement in installed K-series I/O cabinets.
Lifecycle
Record the module, base, terminal board and software revision before maintenance.
Do not substitute K-AIH01 or another K-series AI module without checking HART requirements, channel count, performance and configuration compatibility.
After replacement, validate channel values, scaling, diagnostics, loop integrity and redundant transfer where applicable.
