IS210DSVOH1A | GE Mark VIe DSVO Board | In Stock

Description

Product Introduction

The GE IS210DSVOH1A 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.

What sets the DSVOH1A revision apart is its 16-channel capacity with full optical isolation (2,500 VDC), high-current drive capability (1.0 A continuous per channel), and per-channel status monitoring. Each output features 24 VDC nominal operation, short-circuit protection, over-temperature protection, and output state read-back to confirm the commanded state. For system integrators requiring high-current digital output capability for direct valve and actuator control, this board is the direct OEM solution.

Key Technical Specifications

Key Selling Points & Differentiators

• High-Current Outputs: 1.0 A continuous per channel—directly drives solenoid valves and small actuators without interposing relays.
• 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.
• High-Speed Scanning: 1 ms scan rate for fast output response in protection and interlock applications.
• Robust Design: Designed for high-cycle inductive loads with built-in back-EMF protection.
• 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, and diagnostic performance.
• 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 is the difference between IS210DSVOH1A and IS210DSCBH1A?

A: The DSVOH1A provides 16 high-current outputs (1.0 A per channel) for directly driving solenoid valves and actuators. The DSCBH1A provides 32 lower-current outputs (0.5 A per channel) for general-purpose discrete control. Choose DSVOH1A for applications requiring higher current capacity. Choose DSCBH1A for applications requiring maximum channel density.

Q: What type of outputs does this board support—sourcing or sinking?

A: The DSVOH1A provides sourcing outputs—the board supplies the 24 VDC to the field device. Each channel has a dedicated output terminal and a common return. If your field devices require sinking outputs, you’ll need a different module or an external interface.

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

A: Yes. The outputs are rated for 1.0 A continuous per channel, which covers most small to medium solenoid valves. For larger solenoids or inductive loads exceeding 1.0 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 DSVOH1A 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: How do I know if an output channel is faulty?

A: The DSVOH1A provides per-channel fault detection. If a short circuit, over-temperature, or output mismatch is detected, the board flags a fault. You can monitor this through the Mark VIe Toolkit. The output will automatically recover from a short circuit once the fault condition clears.

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 IS210DSVOH1A 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.
