Description

VMIVME – 7698 – 345 / 350 – 017698 – 345 B: In – Depth Product Guide

1. Product Overview: Brand and Model Identification

The VMIVME – 7698 – 345 (also referred to as 350 – 017698 – 345 B) is a VMEbus digital input/output (I/O) module crafted by VMIC (now a part of Curtiss – Wright), a well – known brand in the domain of rugged embedded computing and industrial automation. This module is designed for high – reliability applications within harsh environments, such as aerospace, defense, and industrial control systems.

2. Core Functions and Applications

The VMIVME – 7698 – 345 serves as a 32 – channel digital I/O module that operates on the VMEbus interface. Its main functions are as follows:

 

  • Input/Output Operations: It can handle 32 TTL/CMOS – compatible digital input channels and 32 open – collector output channels.
  • High – Speed Performance: With a data transfer rate of up to 40 MB/s, it is suitable for real – time control systems.
  • Isolation Feature: The module offers 2,500 VDC galvanic isolation for both input and output channels, protecting against voltage spikes and ground loops.
  • Applications: It finds use in robotics, test and measurement setups, motor control systems, and aerospace avionics.

7. Selection Recommendations

  • Compatibility: Make sure your system has a VMEbus backplane (for example, VMIC VME – 162 or Curtiss – Wright VPX3 – 101).
  • Environment: If your application involves extreme temperatures, opt for the -345 variant (wide – temperature).
  • Budget: For cost – sensitive projects, consider the VMIVME – 7698 – 000 (non – isolated version).

8. Installation and Usage Precautions

  1. Electrostatic Discharge (ESD) Protection: Always use antistatic wrist straps when handling the module.
  2. Power Wiring: Separate the +24 VDC external power from low – voltage signals to prevent noise.
  3. Software Setup: Use VMIC VxWorks Drivers or LabVIEW Plug – ins for configuration.
