Fixed Output 2: DIFFERENTIAL TRIP contact

4 programmable outputs: assignable for alarm, auxiliary trip, fault indication or supervision signals

Logic contact rating: 5 A / 250 VAC, 5 A / 30 VDC resistive load

LED Status Output Indicators: 6 LEDs corresponding to above output channels for local visual indication

LED operating supply: derived from module internal 5 VDC

Communication Interface: Backplane bus output to exchange fault event and diagnostic data with host Multilin relay

Functions of GE MIB30HICE00000

Product Type: GE Multilin High-Impedance Differential Module dedicated for generator and transformer differential protection

Core Differential Protection: Acquires secondary residual current signals from parallel-connected CTs, accurately identifies internal faults of protected equipment and differentiates internal faults from external faults, effectively avoiding false tripping induced by CT saturation.

Integrated Overvoltage Suppression: Embeds a 2000 Ω high-resistance resistor and MOV surge suppression component to clamp excessive overvoltage caused by CT saturation during external system faults.

Binary Logic Control: Accepts external binary enable and blocking signals to implement flexible protection logic switching and operational supervision.

Hard-contact Trip Output: Provides reliable relay contact trip commands to trigger circuit breaker tripping once internal differential faults are detected.

Multi-Functional Status Outputs: Features six configurable logic contacts, including two fixed contacts for device READY status and differential trip indication, plus four fully programmable contacts for customized alarm, auxiliary trip, fault indication and system supervision via EnerVista MII software.

On-Site Visual Indication: Six matching LED indicators display real-time status of each output channel for intuitive on-site inspection.

Continuous Self-Diagnosis & Supervision: Real-time monitors internal hardware and circuit operating conditions, and outputs alarm signals upon module abnormalities or faults.

Backplane Data Communication: Interacts fault records, event logs and diagnostic information with the host Multilin relay via backplane bus to support remote monitoring and professional fault analysis.

Software Configurable Functionality: Supports on-site protection parameter calibration and logic assignment through the EnerVista MII configuration tool.
