Emerson SE4082S1T2B8 Redundant Discrete Output Card

Product Introduction

The Emerson SE4082S1T2B8 Redundant Discrete Output Card is a high-performance output interface module designed for robust industrial control applications. Engineered for the Ovation™ Distributed Control System (DCS), this card provides reliable, high-speed discrete output control with redundancy capabilities to ensure maximum operational availability. The card supports 32 channels of discrete outputs and is suitable for high-side switching of 24V DC signals, making it ideal for driving actuators, relays, and other field devices requiring precise and dependable switching. With its modular design, the card allows for seamless integration into existing control systems, while the redundant configuration ensures continued operation even in the event of component failure.

FAQ

1. What is the maximum current that each output channel can handle?
   Each discrete output channel supports a maximum of 0.5A, suitable for standard DC loads such as relays and solenoids.

2. Does the card support full redundancy operation?
   Yes, the SE4082S1T2B8 is designed for redundant operation, allowing mirrored outputs to maintain functionality in case of a failure.

3. How are the 32 channels organized in the connection boards?
   The card uses 4 x 8-channel DO Mass Connection Boards, enabling independent wiring and simplified installation for each group of 8 outputs.

4. What type of loads can the high-side outputs drive?
   The high-side outputs can drive DC loads up to 24V, including actuators, relays, and other field devices requiring discrete control.

5. Is there short-circuit or overload protection for the outputs?
   Yes, each output channel is protected with internal circuitry against short circuits and overloads to prevent damage.

6. What is the switching speed or response time of the outputs?
   The outputs typically respond in less than 5 milliseconds per channel, suitable for high-speed industrial processes.

7. Can the card be inserted or removed while the system is powered?
   Controlled hot-swapping is supported according to Ovation DCS guidelines, ensuring safety and minimal disruption.

8. How does the DCS monitor the status of the outputs?
   The Ovation DCS continuously monitors each channel for status, fault conditions, and redundancy health.

9. What operating conditions can the card tolerate in terms of temperature and humidity?
   It operates reliably between 0°C and 60°C, with storage temperatures from -40°C to 85°C, and standard industrial humidity tolerance.

10. How does the card ensure immunity against electromagnetic interference (EMI)?
    The card includes electrical isolation and filtering, and it is CE-certified to reduce EMI susceptibility in industrial environments.
