GE MIVII1000E00HI00 Multilin Voltage Protection Relay

🔷Product Overview

The GE MIVII1000E00HI00 is a high-density discrete input (DI) I/O module manufactured by GE / GE Vernova for the Mark VIe distributed control system (DCS) turbine control platform. It serves as the primary digital interface between field contact devices — such as pushbuttons, limit switches, pressure switches, and relay contacts — and the Mark VIe controller. The module digitizes 24 field contact signals and transmits them over the dual-redundant Mark VIe Ethernet control network (IONet).

🔷Core Features and Operational Capabilities

• Onboard Signal Conditioning and Event Timestamping: Filters noise, eliminates mechanical contact bounce, and timestamps state changes at high resolution (1 ms time synchronization over IONet) for accurate Sequence of Event (SOE) recording.
• Dual IONet Redundancy: Equipped with dual Ethernet ports that connect directly to redundant Mark VIe IONet switches, ensuring fault-tolerant communication with the control processor.
• Hot-Swap Capability: Mounts directly to a compatible Mark VIe terminal block via a standard DC-37 pin connector, allowing replacement while powered down without interrupting turbine operation.
• Flexible Field Voltage Compatibility: Supports both dry-contact and wet-contact configurations depending on the connected terminal block, accommodating 24 V, 48 V, or 125 VDC contact sensing.
• Self-Diagnostics and Status LEDs: Continuously monitors power rails, internal processor health, and field wiring circuits, and reports faults via front-panel status LEDs and system diagnostic reports.
