Industrial Control & Processing Architecture
The DS200DSPCH1ADA executes real-time digital signal processing algorithms for large multi-bridge power converters and high-performance drive applications. An integrated Field Programmable Gate Array (FPGA) controls VMEbus access and arbitrates memory transfers through an 8K dual-ported SRAM interface, optimizing backplane bus communication velocity and I/O density scaling. The module functions as either a VME master or slave device while maintaining dedicated program memory and high-speed local I/O connections to run control loops independently of primary backplane traffic, ensuring complete firmware flash compatibility.
Frequently Asked Questions
Q: What rack space does the DS200DSPCH1ADA require when installed in a VME enclosure?
A: The board plugs into a single VME slot but occupies two physical slot widths to accommodate mounted daughterboards (supporting up to four daughterboards).
Q: How does the VME interface manage system bus communications?
A: It operates as an A24/D16 VMEbus slave via an 8K dual-ported SRAM interface, or as a VMEbus master capable of initiating bus transfer cycles with hardware arbitration and asynchronous timeout protection.
Q: What are the input electrical specifications for primary logic and auxiliary power?
A: Main logic power requires +5 VDC at 6 A, while auxiliary power operates across an input voltage range of 18-32 VDC (28 VDC nominal).
Field Installation Guidelines
- Power down the host enclosure and confirm that main logic power and auxiliary DC control buses are isolated prior to board insertion.
- Wear an ESD grounding wrist strap attached to an unpainted chassis point before handling the circuit board.
- Slide the board into the designated VME slot guides, ensuring alignment across both slot positions, and seat the P1/P2 backplane connectors fully.
- Tighten top and bottom front-panel retaining screws to establish ground continuity and prevent vibration-induced dislodgement.
- Verify field relay interface connections and trip solenoid control wiring to ensure voltage ratings do not exceed the 125 VDC maximum threshold.
What's clients say about us
Excellent Emergency Support!
Our production line was down due to a faulty Bently Nevada monitor. We found it in stock here and they shipped it via DHL immediately. Back in operation within 48 hours—truly a lifesaver for our plant.
