Pcm 3810i

The Advantech PCM-3810I is a legacy multifunction PCI-104 module designed for industrial data acquisition and control. As of 2026, it is primarily categorized as a mature/legacy product, used largely for maintaining existing infrastructure rather than in new designs ElmarkEmacinc.

Product Overview & Key Specifications

The PCM-3810I is valued for its ability to integrate multiple measurement functions into a single, compact PC/104-sized board.

* Multifunction I/O: Features 16-channel single-ended or 8-channel differential Analog Inputs (A/D) with 12-bit resolution and a sampling rate of 250 kS/s ApctechMouser.

* Analog Outputs: Provides 2 channels of 12-bit D/A conversion Emacinc.

* Digital I/O & Timers: Includes 16 TTL-compatible digital I/O lines and 3 independent 24-bit counters ElmarkApctech.

* Performance Reliability: Equipped with a 4k word FIFO buffer to prevent data loss during high-speed transfers under multitasking operating systems like Windows AdvantechElmark.

* Form Factor: Compact 96 x 90 mm module with a PCI-104 interface (PCI Rev 2.2 compliant) Alldatasheet.

Market Trends & Insights

The market for the PCM-3810I and similar modules is currently shaped by a transition toward high-speed serial standards.

* Legacy Dominance: Despite being technically "legacy," PCI-104 modules like the PCM-3810I maintain high demand in sectors like rail, aerospace, and energy, where systems are designed for 15–20 year lifespans and re-certification costs are high.

* Shift to PCIe/104: The industrial computing market is rapidly moving toward the PCIe/104 standard (e.g., PCIE-1810), which offers significantly higher bandwidth for Edge AI and high-resolution imaging applications.

* Drop-in Replacement Demand: A significant portion of current sales is for MRO (Maintenance, Repair, and Operations), where companies seek exact hardware matches to avoid costly software rewrites for older operating systems like DOS or Windows Embedded.

* Pricing & Availability: New units are increasingly scarce through standard distribution; most availability is through specialized stockists or refurbished marketplaces. For modern projects, Advantech recommends migrating to the PCIE-1800 series for better long-term support and performance Alibaba.
