FUNCTIONAL DESCRIPTION:
DS3800HROA1A is a High-Performance Relay Output Board manufactured and designed by General Electric as part of the Mark IV Series used in GE Speedtronic Gas Turbine Control Systems. A Relay Output Card serves as an interface between a low-voltage control system and high-power electrical components. It works by receiving signals from the control system and activating or deactivating relays to switch external devices on or off. This process enables automation and control over various subsystems. These boards are designed to switch both AC and DC loads safely, often supporting currents ranging from a few amperes to several tens of amperes, depending on the relay type. To ensure safety and protect connected devices, high-performance relay boards also incorporate electrical isolation mechanisms, such as optical or electromagnetic isolation. This prevents voltage spikes or electrical noise from interfering with the control system, reducing the risk of damage or malfunction.
FEATURES OF HIGH-PERFORMANCE RELAY OUTPUT BOARDS
A high-performance relay output board is designed with several features to enhance efficiency, safety, and reliability in control systems. Fast switching speed ensures minimal delay in response to control signals, making them ideal for real-time automation applications. Multiple relay channels allow simultaneous control of different devices, improving the system’s flexibility. High-voltage and high-current handling capacity enables the board to operate industrial machinery and power distribution systems without failure.
Each input circuit features a jumper-selectable slow/fast filter, suitable for AC inputs and slow DC inputs in noisy environments. For faster DC inputs, the filter can be manually disabled, reducing the board’s typical response time to 10 µs. With an input impedance of 1.8K Ohms, it supports a wide input range. Schmitt triggers ensure reliable logic signals, preventing false state changes and unwanted interrupts.
This 8-bit PC/104 board (with 16-bit pass-through connectors) is compatible with embedded systems supporting PC/104 or PC/104+ modules. It comes with right-angle pin I/O connectors by default but can be ordered with vertical connectors to accommodate system or enclosure constraints. This high-density I/O board offers various configurations, including an economy version (no-COS), extended temperature range (-40 to +85°C), higher input ranges, and options without relays. Customize it to fit your OEM application, ensuring cost-effective and efficient integration.

What is the voltage and current rating of the relay outputs?
The relay outputs are designed to handle a specific voltage and current rating suitable for industrial applications. Common voltage ratings range from 24V to 250V AC/DC, while current ratings typically vary between 1A and 10A per relay. The exact specifications depend on the card model and should be verified in the manufacturer’s datasheet.
How does the relay output card provide isolation between control and load circuits?
The relay output card ensures electrical isolation through the use of relay coils and contacts, preventing direct electrical connection between the control system and the load. This isolation protects low-voltage control circuits from high-voltage fluctuations, reducing the risk of electrical noise, transients, or damage due to voltage spikes on the load side.
What type of signal does the relay output card receive for activation?
The relay output card typically receives digital control signals (on/off) from the turbine control system. These signals may be in the form of TTL (Transistor-Transistor Logic) or optocoupler-isolated inputs, depending on the specific system design. Some cards may also support pulse-width modulation (PWM) or latching signals for specific applications.
