Description

Product Overview

The GE DS3820EPSAIA1A is a high-performance High-Speed CAN Bus Interface Module designed for GE’s Mark IV Speedtronic turbine control systems. Engineered to enable real-time data exchange between field devices and the control system, this module supports seamless integration of analog/digital sensors, actuators, and other Mark IV components in mission-critical industrial environments. As a core component of the Mark IV ecosystem, the DS3820EPSAIA1A ensures reliable communication with up to 1Mbps data transfer rates, making it ideal for gas/steam turbine control, oil & gas platforms, and heavy manufacturing applications.

 

Featuring advanced CAN protocol support (ISO 11898-2), the DS3820EPSAIA1A processes bidirectional data between the Mark IV system and connected devices, including pressure transmitters, temperature probes, and motor drives. Its microprocessor-based architecture provides error detection, data buffering, and protocol conversion, ensuring stable operation under high EMI conditions. The module interfaces with the Mark IV backplane via a dedicated CAN Bus connector, eliminating the need for external converters and reducing cabling complexity.

 

Built with industrial-grade components, the DS3820EPSAIA1A withstands extreme temperatures (-20°C to +60°C) and supports hot-swappable replacement without system shutdowns. Its front-panel LED indicators provide real-time status updates on power, communication, and error conditions, simplifying troubleshooting. By embedding this module into control architectures, operators gain actionable insights to optimize system performance and reduce unplanned downtime, making it an indispensable asset in high-reliability applications.
