IS210AEBIH1ADC | Mark VIe Isolated Analog Input | New Surplus

Description

Product Introduction

The GE IS210AEBIH1ADC is a VMEbus isolated analog input board from the Mark VIe Speedtronic series, purpose-built for high-accuracy measurement of process signals in turbine control applications. This board interfaces with field devices such as pressure transmitters, temperature transmitters, flow meters, and position transducers to provide critical process data for turbine control, protection, and monitoring. The “ADC” suffix indicates a maximum environment conformal coated board with the highest level of moisture, chemical, and particulate protection available, combined with the enhanced H1A revision features.

What sets the AEBIH1ADC revision apart is its 8-channel capacity with full isolation (2,500 VDC between channels and backplane), software-selectable input types (4–20 mA or 0–10 V), 18-bit resolution for superior measurement accuracy, advanced diagnostics including open-circuit, overrange, and out-of-range detection, and the premium-grade urethane conformal coating that provides maximum protection in the harshest operating conditions. The board includes a built-in loop power supply for 2-wire transmitters, programmable filter time constants, and online calibration verification. For system integrators requiring the highest accuracy isolated analog input capability with advanced diagnostics and maximum environmental protection in aggressive environments, this board represents the ultimate OEM solution.

Key Technical Specifications

Key Selling Points & Differentiators

• Maximum Environment Coating Advantage: The “ADC” suffix provides the thickest, most robust premium urethane coating (0.10–0.18 mm) rated for continuous exposure to high humidity, salt fog, chemical vapors, and airborne particulates. This is the ultimate protection variant for offshore platforms, coastal installations, desalination plants, chemical processing, pulp and paper mills, and mining operations where environmental contaminants are most severe.
• Enhanced 18-Bit Resolution: Superior measurement accuracy for critical process parameters—twice the resolution of 16-bit variants.
• Full Channel Isolation: 2,500 VDC isolation between channels and backplane—eliminates ground loops and protects the control system from field wiring faults.
• Dual Input Type Support: Software-selectable 4–20 mA or 0–10 V per channel—flexible for a wide range of field devices.
• Built-in Loop Power: 24 VDC at 30 mA per channel—supports 2-wire transmitters with higher power requirements.
• Advanced Diagnostics: Open-circuit, overrange, and out-of-range detection for comprehensive fault identification.
• Faster Scan Rate: 40 ms for all 8 channels—improved response for control applications.
• Live Test Verified: Every board undergoes a 48-hour burn-in with all 8 channels exercised across the full input range. We log accuracy, isolation integrity, diagnostic performance, and temperature stability. Coated boards are visually inspected for complete coverage, thickness consistency, and absence of bubbles, voids, or pinholes using magnification and UV light.
• 90-Day Warranty: Covers functional defects. If it fails under normal operating conditions, we replace it. No restocking fee for verified returns.
• OEM Traceability: All units come from audited surplus channels with original GE anti-static bags and serialized labels. No clones, no pull-and-refurbish from unknown sources.
• Configuration Backup Service (Free): Upon request, we extract and archive your existing board’s firmware version and configuration before shipment.

Frequently Asked Questions (FAQ)

Q: What does the “ADC” suffix mean on IS210AEBIH1ADC?

A: The “ADC” indicates maximum environment conformal coating combined with the enhanced H1A revision. Specifically, it means the board has a premium-grade urethane conformal coating (0.10–0.18 mm) applied to the entire PCB assembly for the highest level of moisture, chemical, and particulate protection available in the AEBI series, along with all enhanced H1A features (18-bit resolution, advanced diagnostics, 40 ms scan rate). Electrically and functionally they are identical in terms of analog input capability. The coating adds protection; the enhanced H1A features provide superior measurement accuracy and diagnostic capability.

Q: What is the difference between IS210AEBIH1ADC and IS210AEBIH1A?

A: The H1A is the base non-coated revision; the H1ADC has maximum environment conformal coating, 18-bit resolution (vs. 16-bit), enhanced diagnostics, and faster scan rate (40 ms vs. 50 ms). The coating protects against humidity, salt fog, and chemical vapors while the enhanced features provide superior measurement capability. If you need the highest accuracy, advanced diagnostics, and maximum environmental protection, choose H1ADC.

Q: What is the difference between IS210AEBIH1ADC and IS210AEABH1ABA?

A: The AEBIH1ADC provides 18-bit resolution, advanced diagnostics, faster scan rate (40 ms), and maximum environment coating. The AEABH1ABA provides 16-bit resolution, standard diagnostics, slower scan rate (50 ms), and standard conformal coating. Choose AEBIH1ADC for the highest accuracy, advanced diagnostics, and maximum environmental protection. Choose AEABH1ABA for standard analog input applications with conformal coating.

Q: Does the maximum coating affect analog input performance, isolation, or diagnostics?

A: Good question. The coating adds about 0.15 mm to the board thickness, which does not affect VME slot fitment—clearances are designed for it. Analog input accuracy, isolation voltage, diagnostic performance, and scan rate are identical to the non-coated enhanced H1A. The coating does not affect the electrical characteristics of the analog circuits—it only provides environmental protection. Do not remove the coating or scrape it off—it voids the warranty and compromises protection.

Q: What is the benefit of the 18-bit resolution?

A: 18-bit resolution provides approximately 262,000 counts vs. 65,000 counts for 16-bit—four times the measurement resolution. This enables detection of the smallest signal changes—critical for applications requiring high precision such as high-accuracy flow measurement and critical pressure control.

Q: Can I use this board with both 2-wire and 4-wire transmitters?

A: Yes. The built-in loop power supply (24 VDC) supports 2-wire transmitters (loop-powered) with up to 30 mA per channel. For 4-wire transmitters (externally powered), you can disable the loop power on each channel and use the board’s differential input configuration. Input type (current or voltage) is software-selectable per channel.

Q: Is this board hot-swappable?

A: No. The Mark VIe VME backplane does not support live insertion. You must de-energize the rack, ground yourself, and wait 30 seconds for bulk capacitors to discharge. We’ve seen field crews pull an AEBI while the cabinet was still powered—it damaged the analog input circuits and the backplane connector. Don’t risk it.

Q: What is the typical lead time for this part?

A: We stock these on the shelf—usually ship within 24 hours of order placement and payment confirmation. For international orders, add 3–5 days for customs. If you need expedited (overnight air), we can do that, but you’ll need to coordinate with our logistics team for the cut-off time.

Q: Does this board work with the newer Mark VIeS (SIL-rated) cabinets?

A: To be direct: no. The IS210AEBIH1ADC is not SIL-certified. It’s meant for standard Mark VIe industrial control. The SIL-rated systems use the IS220AEBI (with additional redundancy, diagnostic coverage, and separate safety shutdown path). Mixing them violates your site’s safety integrity level. If you’re in a SIL environment, we can source the correct variant but it will have a different model number.

Q: What’s your return policy if this doesn’t solve my analog input issue?

A: If the board is electrically functional (passes our QC test) but doesn’t correct your fault, we’ll accept a return within 30 days provided the board shows no physical damage and the connectors are intact. We do charge a 15% restocking fee if the fault was due to field wiring issues, configuration errors, or toolkit compatibility problems. We’ll work with you over the phone or email to diagnose the problem before we ship—our goal is to get you running, not to ship boxes back and forth.
