IS210DSVOH2BA | GE Mark VIe DSVO Board | In Stock

Description

Product Introduction

The GE IS210DSVOH2BA is a VMEbus digital output board from the Mark VIe Speedtronic series, purpose-built for high-current discrete output control in turbine applications. This board provides optically isolated outputs for directly driving solenoid valves, actuators, and other higher-current field devices—critical for turbine sequencing, protection, and control functions. The “BA” suffix indicates a conformal coated board with enhanced moisture and contaminant resistance for harsh environments, combined with the enhanced H2B revision features.

What sets the DSVOH2BA revision apart is its 16-channel capacity with full optical isolation (2,500 VDC), enhanced high-current drive capability (1.5 A continuous per channel), improved diagnostic coverage, and the acrylic conformal coating that protects output driver circuitry from humidity, salt spray, and airborne particulates. Each output features 24 VDC nominal operation, short-circuit protection, over-temperature protection, output state read-back, and advanced fault diagnostics. For system integrators requiring higher current digital output capability with enhanced diagnostics and environmental protection for demanding valve and actuator applications, this board is the direct OEM solution.

Key Technical Specifications

Key Selling Points & Differentiators

• Conformal Coated for Harsh Environments: The “BA” suffix provides acrylic coating that protects output driver circuitry against humidity, salt spray, and airborne contaminants—ideal for offshore platforms, coastal plants, and high-humidity installations.
• Higher Current Capacity: 1.5 A continuous per channel—drives larger solenoid valves and actuators without interposing relays.
• Enhanced Diagnostics: Open-load detection identifies broken wiring or disconnected field devices.
• Faster Response: <1.5 ms typical response time—improved over H1A variants.
• Full Optical Isolation: 2,500 VDC isolation protects the backplane and control system from field wiring faults.
• Output State Verification: Per-channel read-back confirms the commanded output state—critical for diagnostic and safety applications.
• Short-Circuit Protection: Per-channel protection with auto-recovery prevents damage to output drivers.
• Live Test Verified: Every board undergoes a 48-hour burn-in with all 16 outputs exercised under load. We log response time, short-circuit protection, open-load detection, and diagnostic performance. Coated boards are visually inspected for complete coverage and absence of bubbles.
• 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.
• 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 “BA” suffix mean on IS210DSVOH2BA?

A: The “BA” indicates conformal coating combined with the H2B enhanced revision. Specifically, it means the board has an acrylic conformal coating (0.02–0.05 mm) applied to the entire PCB assembly for moisture and contaminant protection, along with all H2B features (1.5 A outputs, open-load detection, faster response). Electrically and functionally they are identical in terms of output capability. The coating adds protection; the H2B features provide enhanced performance and diagnostic capability.

Q: What is the difference between IS210DSVOH2BA and IS210DSVOH1AA?

A: The H2BA is a significant upgrade: higher current capacity (1.5 A vs. 1.0 A), faster response (<1.5 ms vs. <2 ms), enhanced diagnostics including open-load detection, and improved short-circuit protection. The H2BA also requires Mark VIe Toolkit v6.5 or higher vs. v6.0 for H1AA. If you need higher current and enhanced diagnostics with conformal coating, choose H2BA.

Q: What is the open-load detection feature?

A: The H2BA includes open-load detection that identifies when a field device is not drawing current as expected—indicating a broken wire, disconnected load, or faulty field device. This diagnostic provides early warning of wiring issues before they affect operation. We’ve seen sites use this to identify failed solenoid valves before they caused a turbine trip.

Q: Does the conformal coating affect output performance, protection, or diagnostics?

A: No. The coating is applied after functional testing, so it does not affect the electrical characteristics of the output driver circuits. Current capacity, protection thresholds, and diagnostic performance are identical to the non-coated H2B. The coating only provides environmental protection.

Q: Can I use this board to directly control solenoid valves?

A: Yes. The outputs are rated for 1.5 A continuous per channel, which covers most medium solenoid valves. For larger solenoids or inductive loads exceeding 1.5 A, we recommend using an interposing relay or contactor. Always install a suppression diode across DC coils to protect the output driver from back-EMF.

Q: What is the output state verification feature?

A: The H2BA reads back the actual output state and compares it to the commanded state. If the output does not respond as commanded—due to a short circuit, open circuit, or driver failure—the board reports a fault. This is critical for safety applications where you need to verify that the output achieved the desired state.

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 a DSVO while the cabinet was still powered—it damaged the output drivers and the backplane connector.

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), coordinate with our logistics team.

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

A: To be direct: no. The IS210DSVOH2BA is not SIL-certified. It’s meant for standard Mark VIe industrial control. The SIL-rated systems use the IS220DSVO (with additional redundancy, diagnostic coverage, and separate safety shutdown path). Mixing them violates your site’s safety integrity level.

Q: What’s your return policy if this doesn’t solve my digital output 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.
