GE IS2020ISUCG1 IS2020ISUCG1A Mark VI Analog Input VME Card

The GE IS2020ISUCG1 card converts analog field signals for the Mark VI system. This analog input VME card also carries the revision code IS2020ISUCG1A . It accepts current and voltage inputs from field transmitters. The card provides accurate process data for turbine monitoring and control.

Technical Specifications of GE IS2020ISUCG1 IS2020ISUCG1A

Component Count and Board Construction

This GE IS2020ISUCG1 card contains over 180 discrete components on its surface. You will find multiple operational amplifiers for signal conditioning. Furthermore, the card 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 IS2020ISUCG1A revision provides a front-face terminal block for field wiring. Moreover, the card 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 IS2020ISUCG1 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 card provides 1500 V isolation between field and logic sides. Always verify the IS2020ISUCG1A jumper settings before initial power-up.
