GE IS200VAICH1B IS200VAICH1BBB Mark VI VME Analog Input Card

The GE IS200VAICH1B card converts analog field signals for the Mark VI system. This VME analog input card also carries the revision code IS200VAICH1BBB . It accepts current and voltage inputs from field transmitters. The card provides accurate process data for turbine monitoring and control.

Technical Specifications of GE IS200VAICH1B IS200VAICH1BBB

Component Count and Board Construction

This GE IS200VAICH1B board contains over 180 discrete components on its surface. You will find multiple operational amplifiers for signal conditioning. Furthermore, the board includes precision voltage reference circuits for accuracy. The assembly also features opto-isolators for channel-to-channel isolation.

Interfaces, Energy Storage, and Signal Processing

The IS200VAICH1BBB revision provides a front-face terminal block for field wiring. Moreover, the board uses capacitors for analog filter networks. These capacitors store minimal energy but provide critical noise rejection. Each channel includes a dedicated analog-to-digital converter for simultaneous sampling.

Functional Logic and Application Context

This Mark VI card scans all eight input channels continuously. It then transmits digital values to the main controller via the VME bus. The GE IS200VAICH1B also performs open-wire detection on 4-20 mA loops. Additionally, it applies software-configurable scaling to each input channel. Consequently, you can adapt the card to various sensor types easily.

Installation and Environmental Limits

You must power down the VME rack before inserting this analog input card. The operating temperature range spans 0°C to 60°C . Furthermore, the board provides 1500 V isolation between field and logic sides. Always verify the IS200VAICH1BBB jumper settings before initial power-up.
