Hitachi AEH002A – Analog Input I/O Module | HISEC / EX Series DCS Platform
Engineering Background
The Hitachi AEH002A is a dedicated analog input card designed for Hitachi’s HISEC and EX Series Distributed Control Systems (DCS). Engineered to meet the demanding signal acquisition requirements of continuous process industries, this module provides reliable, high-resolution analog data collection from field instrumentation directly into the DCS controller backbone.
Product Positioning
As a genuine Hitachi OEM I/O card, the AEH002A serves as a critical front-end acquisition node in large-scale process automation architectures. It is the preferred choice for procurement engineers seeking a drop-in replacement or system expansion card that maintains full compatibility with existing Hitachi DCS infrastructure without requiring software reconfiguration.

Engineering Advantages
- Genuine OEM Part: Direct Hitachi lineage ensures full firmware and hardware compatibility with HISEC/EX DCS controllers
- Hot-swap Capable: Supports live insertion/removal in compatible rack configurations, minimizing process downtime
- High Signal Integrity: Onboard filtering and isolation reduce noise pickup from field wiring
- Compact Form Factor: Single-slot design maximizes rack density in space-constrained control rooms
- Long Service Life: Industrial-grade components rated for continuous 24/7 operation
- Backward Compatible: Interoperable with legacy HISEC installations without engineering changes
System Architecture & Signal Flow
The AEH002A plugs directly into the Hitachi DCS I/O rack backplane. Field transmitters (4–20 mA loops or voltage sources) connect via the front-panel terminal block. The onboard A/D converter digitizes each channel and passes engineering-unit values to the DCS controller via the backplane data bus. The controller then makes these values available to the process historian, HMI displays, and control algorithms in real time. No external signal conditioners are required for standard 4–20 mA HART-compatible transmitters.

Technical FAQ
Q: Is the AEH002A compatible with both HISEC and EX Series DCS?
A: Yes. The AEH002A is designed for the Hitachi HISEC platform and is also compatible with EX Series racks sharing the same backplane standard. Confirm your rack model with our technical team before ordering.
Q: Can this card be used as a direct replacement without DCS reconfiguration?
A: In most cases, yes — provided the replacement card carries the same firmware revision. Contact us with your existing card’s firmware label for confirmation.
Q: Do you provide a warranty?
A: Yes. All units carry a 90-day functional warranty. Extended warranty options are available on request.
Q: What is the typical lead time?
A: In-stock units ship within 2–3 business days. For sourced units, lead time is 7–15 business days depending on origin.
Q: Can you provide a Certificate of Conformance (CoC) or test report?
A: Yes. CoC and inspection reports are available upon request for quality-critical procurement.
