Universal PCI, 512KB Memory Board with DI/DO

● On-board 512K bytes SRAM for PCI-M512/PCI-M512U
● 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)
● PCI-M512U supports 5V and 3.3V PCI bus


● DOS Lib and TC/BC/MSC sample program (with source codes)
● DLL and OCX SDK for Windows 98/NT/2000
● DLL and OCX SDK for 32-bit and 64-bit Windows XP/2003/Vista/7
● VB/VC/Delphi/BCB/VB.NET/C#.NET sample programs with source codes are included


The PCI-M512/PCI-M512U provides battery-backup 512 KB SRAM, 12-bit DI and 16-bit DO. In addition, the PCI-M512U supports both 5 V and 3.3 V PCI bus, while the PCI-M512 supports 5 V PCI bus only. The PCI-M512U (Universal PCI version) is designed as a drop-in replacement for the PCI-M512 (PCI version), so users can replace a PCI-M512 by a PCI-M512U directly without any software or driver modification.

Users can use the DB-16P to connect the input ports (CN2) for isolation purpose, or use DB-16R to interface to the output ports (CN1) for relay control.

The PCI-M512/PCI-M512U is equipped with two Li-batteries to maintain the content of the 512 KB SRAM when PC power loss occurs. The two Li-batteries can continue supplying power to the SRAM to retain the important data for 10 years. The two-battery design also makes it safe to replace new batteries without losing data; when one battery is taken out for replacing a new one, the other continues to provide power to the SRAM.

4 LED indicators on the board are provided for giving clear understanding of the battery states such as normal, low voltage or fault. The PCI-M512/PCI-M512U is an ideal solution for improving system reliability.
