The AI02J Analog Input module processes up to 16 high level, group isolated, analog input field signals. Each channel is independently configurable for either 4 to 20 mA or 1 to +5 VDC ranges. FC 221 (I/O Device Definition) sets AI module operating parameters and each input channel is configured using FC 222 (Analog Input Channel) to set individual input channel parameters such as engineering units, High/Low alarm limits, etc.
16 independently configurable channels supporting
Up to 24 HART v5.4 secondary variables Total
Sec HART variables available to control logic
A/D resolution of each channel is configurable from 12 to 16 bits with polarity. The AI02J module has one A/D converter for all 16 input channels. The module will update 16 input channels in 100 msecs. In current mode, the AI02J module supports HART v5.4 instruments and provides short circuit protection by limiting current to a maximum of 96 mA. The AI02J module will also detect an open circuit in less than 5 seconds. The module requires a continuous power supply of 24 VDC ± 10%, drawing a typical current of 100 mA through the POWER TB connection on cHBX01L or VBX01T termination units.
It features a physical 1x16 group isolation structure providing 1500 V galvanically isolated protection between the field signals and the logic circuitry for up to 1 minute. Under current mode, the input impedance is 250 Ω, while voltage mode utilizes 250 kΩ or greater. The single internal HART modem extracts up to 24 secondary variables total, with a maximum of 4 variables per channel and a typical update rate of 2.5 seconds. Hardware diagnostics are available locally via the front plate mini USB interface and status LEDs, or remotely via the HN800 device diagnostic channel.

Thermal Power & Gas Turbines
Acquires steam turbine casing vibration, bearing temperature, and lube oil pressure signals at millisecond-level refresh rates in generator unit control, executing anti-surge and overspeed trip safety interlocks.
Nuclear Power Generation
Monitors steam generator secondary-side water levels and feedwater analog flow rates at high frequency within nuclear island peripheral utilities and conventional island control loops, providing real-time tuning parameters.
Hydropower & Pumped Storage
High-speed polls voltage signals of servo valve openings and guide vane positions within hydro-turbine generator unit governor controls, responding to head fluctuations within milliseconds.
Petroleum Refining
Connects to field HART smart transmitters in hydrocracking and high-pressure reactor process flows, continuously acquiring pressure and reaction temperature trends in core reaction zones.
Ironmaking & Blast Furnaces
Centrally reviews data from differential pressure and flow transmitters across loops in blast furnace cooling water circulation and hot blast stove control systems, preventing safety melting caused by localized overheating.
Pulp, Paper & Fiber Processing
Inputs tension and micro-pressure signals in quick response mode within paper machine headbox pressure control and wire/drying section tension adjustment loops, reducing paper break rates.
During field installation the module must be securely snapped onto its matching SD series DIN rail base, and short-circuiting or grounding signal wires before isolating external channel power is strictly prohibited to prevent burning the sampling resistors.
Since this quick-response module is frequently deployed in critical interlock loops, the corresponding field loop must be switched to manual control or its soft interlocks temporarily bypassed prior to an overhaul or hot-swapping, avoiding sudden system trips caused by signal steps during insertion or removal. Additionally, periodically review its built-in HART smart diagnostic data to promptly clear sporadic channel open-circuits or instrument configuration conflicts.

Technical notes
Technical notes
The AI02J is a 16-channel, group-isolated analog input module for 4-20 mA or 1-5 VDC signals, drawing 100 mA from a 24 VDC supply via cHBX01L/VBX01T units. It provides 1500 V galvanic isolation for 1 minute and updates all channels within 100 msecs using a shared 16-bit A/D converter. The input impedance is 250 Ω in current mode with 96 mA short-circuit protection, and ≥250 kΩ in voltage mode. A single internal modem polls up to 24 secondary variables from HART v5.4 field devices, while hardware status is tracked via front LEDs, a mini USB port, or the HN800 diagnostic channel.
