GE VMIVME-2128 Product Description
Product Overview
The GE VMIVME-2128 is a 128-channel high-voltage digital output board for VMEbus-based industrial control and test systems. It belongs to the GE VMIC embedded I/O product family and delivers high-density, high-current open-collector outputs for driving industrial field loads.
This module occupies a single 6U VME chassis slot and supports output voltages from 5 VDC to 48 VDC. It integrates built-in test (BIT) logic and multi-level protection circuits to ensure reliable operation in mission-critical scenarios. With its high channel density and robust fault protection, it is widely used for high-speed control, data acquisition and automated test systems across industrial, aerospace and energy sectors.
GE VMIVME-2128
Core Product Features
- 128 independent open-collector output channels deliver high-density digital control in one standard 6U VME slot.
- Wide 5 VDC to 48 VDC output range adapts to various industrial relays, contactors and indicator loads.
- Each channel supports up to 600 mA sink current for medium-power field device driving.
- Built-in test logic enables software-controlled verification of each channel for fast on-site fault isolation.
- Automatic surge current shutdown and thermal shutdown protect the module from overload and overheating damage.
- Output clamp diodes suppress inductive flyback voltage when switching relay and solenoid loads.
- Front-panel status LED provides clear visual indication of module power and fault conditions.
- Fully compliant with VMEbus ANSI/IEEE STD 1014-1987 standards for broad system compatibility.
