GE IS200EMIOH1A IS200EMIOH1ACA Speedtronic Printed Circuit Board – Mark VI Series

Technical Specifications

The GE IS200EMIOH1A (also IS200EMIOH1ACA) handles input and output for Speedtronic turbine control systems. This board measures 30.5 cm in length and 25.4 cm in width. It weighs approximately 1.1 kg. The unit contains 16 digital inputs, 16 digital outputs, and 8 analog inputs. A single 64-pin backplane connector provides system interface. Additionally, the board features two RJ45 ports for configuration access. The GE IS200EMIOH1A IS200EMIOH1ACA stores 512 KB of I/O mapping data in flash memory. It also holds 256 KB of buffer memory for data logging. This module uses no battery for energy storage.

Design and Integration

This GE IS200EMIOH1A IS200EMIOH1ACA connects field devices to the Speedtronic controller. The 16 digital inputs accept dry contacts or 24 V signals. Meanwhile, the 16 digital outputs drive relays and indicator lamps directly. The 8 analog inputs monitor pressure and temperature transmitters. Therefore, the board eliminates multiple separate I/O modules. The two RJ45 ports allow engineers to monitor real-time data remotely. For a similar control component, see the RMS-TSG-TZ-C on Alibaba. However, that static trip relay handles protection rather than general I/O.

Reliability and Operation

The GE IS200EMIOH1A IS200EMIOH1ACA operates from -30°C to +65°C. Its flash memory retains I/O mapping without any external battery. Consequently, you avoid periodic maintenance for memory backup. The board meets GE’s scan time specification of 5 milliseconds. Each unit undergoes 48-hour continuous I/O cycling before shipping.
