产品名称
VMIC+ASSY 11993R2 & ASSY 11994R13 High-Speed Analog I/O Expansion Kit
产品说明
VMIC+ASSY 11993R2 is the front-end signal-conditioning and conversion board, while ASSY 11994R13 is the companion backplane adapter and terminal block assembly. Together, the VMIC+ASSY 11993R2 and ASSY 11994R13 form a complete high-speed analog input/output subsystem that plugs directly into any VME64x or PMC-compatible rack. Designed under the legacy VMIC brand (now part of Emerson’s PACSystems portfolio), VMIC+ASSY 11993R2 delivers 32 differential analog inputs and 8 analog outputs with 250 kS/s per-channel throughput, and ASSY 11994R13 provides hot-swappable spring-cage terminals, LED diagnostics, and 500 Vrms channel-to-ground isolation. Both ASSY 11993R2 and ASSY 11994R13 are engineered for real-time control loops that demand micro-second-level determinism and superior noise immunity.

选型建议
Choose VMIC+ASSY 11993R2 and ASSY 11994R13 when your application demands:
-
Simultaneous high-speed sampling (≥200 kS/s) with deterministic latency.
-
Wide temperature operation and ATEX Zone 2 certification.
-
On-board FPGA for custom signal processing without burdening the PLC.
If only slow-speed monitoring is required, Acromag 3515 may be cost-effective; if software-centric development tools outweigh ruggedization, NI PXIe-4339 is viable.
注意事项
• Ensure the VME rack provides 5 V/32 A and 3.3 V/8 A rails to meet the combined 7–9 W draw of VMIC+ASSY 11993R2 and ASSY 11994R13.
• Use shielded twisted-pair for analog inputs longer than 3 m to maintain 90 dB CMRR.
• Firmware revisions prior to Rev D require a jumper change on ASSY 11994R13 for 24 V digital compatibility—check the factory label.
• Periodic calibration is recommended every 24 months or 8,000 operating hours to retain 16-bit accuracy.
