HollySys K-AIH01 8-Channel HART Analog Input Module
HOLLiAS MACS-K current-input module with eight channels, HART communication and optional redundancy.
Product Identification
HollySys K-AIH01 is a K-series eight-channel analog-input module for current signals with HART communication.
The module belongs to the HOLLiAS MACS-K I/O family and is used where process values and HART device information must be integrated into the control system. It follows the K-AI01 analog-input function while adding HART 5 communication capability.
A complete installation requires the compatible base and terminal-board arrangement, channel wiring, field power, HART loop conditions, redundancy setting and MACS-K configuration to be checked together.

Functions
Digitizes eight current-input channels for the MACS-K control system.
Adds HART 5 communication for compatible smart field instruments.
Supports approved two-wire and four-wire transmitter arrangements.
Can be engineered in an optional redundant module configuration.
Provides module and channel status information to the control system.
Supports maintenance access to HART information when the complete system configuration is qualified.
System Integration
Select the approved base and terminal board for the required wiring and redundancy arrangement.
Confirm loop power, polarity, shield grounding and field-device HART compatibility.
Configure the exact signal type, range, engineering units, filtering and diagnostic handling for every channel.
In a redundant installation, verify primary/standby status and test transfer behavior before service.
Confirm the MACS-K software and module revision supported by the installed controller.
Applications
Eight-channel 4–20 mA transmitter input.
HART pressure, flow, level and temperature transmitters.
Process-unit instrument monitoring.
Redundant analog-input stations.
Brownfield MACS-K I/O maintenance.
Lifecycle
Record the module revision, base, terminal board and MACS-K software version before replacement.
K-AIH01 should not be confused with K-AI01: K-AIH01 adds HART communication to the eight-channel current-input function.
After replacement, validate analog scaling, HART communication, diagnostics and redundancy where configured.
FAQ
Q1. What distinguishes K-AIH01 from K-AI01?
K-AIH01 adds HART 5 communication to the eight-channel current-input function.
Q2. How many channels are provided?
The module provides eight analog-input channels.
Q3. Can it be configured redundantly?
Yes. HollySys lists optional redundancy for this module family when the approved base and system configuration are used.
Q4. Does the module supply all field-loop power requirements by itself?
The complete loop-power and terminal arrangement must be engineered with the approved base, terminal board and cabinet power system.
Q5. Can HART be used without configuration?
No. The field device, wiring, loop conditions, module channel and MACS-K asset or control configuration must support HART.
Q6. What should be tested after replacement?
Test every analog value, scaling, HART communication, channel diagnostic and redundant transfer where used.
