GE VMIVME7698 High Performance Embedded Controller Module

Description

The GE VMIVME7698 is a 64-channel isolated digital input board designed for industrial automation and control systems, built upon the robust VMEbus architecture. It is widely used across industries such as manufacturing, energy, and process control where high reliability and signal integrity are critical. This module enables simultaneous monitoring of multiple digital signals while maintaining electrical isolation between channels, which is essential for preventing signal interference and ensuring accurate system status monitoring. The GE VMIVME7698 enhances control system stability, particularly in complex environments where many discrete inputs must be managed with high precision.

Functionally, the VMIVME7698 integrates 64 optically isolated input channels, each independent and capable of multiple intelligent functions including change of state (COS) detection, sequence of events (SOE) logging, pulse accumulation, and time tagging. The module supports wide input voltage ranges from 5 to 250 V DC or 4 to 240 V AC, and offers substantial isolation of 1500 V DC or 1100 V RMS between channels and from the VME backplane. This isolation helps to protect the device and reduce cross-talk, ensuring signal clarity. The module operates with programmable de-jitter times for eliminating input signal ‘noise’ and supports 1 millisecond measurement resolution for real-time response needs. When paired with vibration and surge suppression panels, it complies with stringent ANSI/IEEE surge protection standards, making it suitable for harsh industrial electrical environments.

The GE VMIVME7698 features a multifunctional intelligent controller embedded on the board, managing each channel’s state and timing functions independently, and it can lock multiple input signals within each millisecond. The state change timer is programmable up to 65 seconds, providing flexibility in timing-sensitive applications. This board supports a range of monitoring scenarios including both supervised and unsupervised inputs and is built to conform to VME/VME64 form factors for straightforward integration into legacy or modern VME backplanes. Its reliability and functionality make it ideal for applications requiring detailed event capturing and input state monitoring, such as protective relaying, alarm annunciation, and machine status tracking in industrial facilities.
