Introduction:
The PCI-M512U is the new generation product of the PCI-M512. Besides providing the functions of 512KB SRAM with battery-backup, 12-bit DI and 16-bit DO, the PCI-M512U supports both 5V and 3.3V PCI slot and is fully compatible with the PCI-M512.

The PCI-M512U equips two Li-batteries to maintain content in the event of PC power loss. The two Li-batteries can continue supplying power to 512KB SRAM to retain the important data for 10 years; and the two-battery design is safe to maintain the data when replacing new batteries.

The PCI-M512U also provides 4 LED indicators to display the battery states. It is easy to know the status of the two Li-batteries is normal, low voltage or fault by the 4 LED indicators.

The PCI-M512U is an ideal solution for system reliability.


Features:
-On-board 512K Bytes SRAM
-Two Li-batteries, BT1 & BT2, for battery-backup the data of SRAM
-Two indicators, low-battery & bad-battery, for battery BT1
-Another two indicators, low-battery & bad-battery, for battery BT2
-16-bit general purpose TTL-compatible D/O or relay (with daughter board DB-16R or DB-24PR)
-12-bit general propose TTL-compatible D/I or isolated input (with daughter board DB-16P)
-Universal PCI card, supports both 5V and 3.3V PCI bus.
