1 SFISA-7353 ISA bus is isolated digital input and output interface cards can be easily applied to the computer with ISA bus slots. PC operating system can use the popular Windows family, Unix and other operating systems and professional data acquisition and analysis software, LabVIEW, LabWindows / CVI environments. 
 SFISA-7353 isolated digital input output interface card with 16 isolated digital input channels and 16 isolated digital output channels. 
 Digital output with zero power and data latch function, please. In order to improve the output drive capability with a MC1413 or ULN2003 door open collector level as the output driver. 
 Digital inputs with 2-way option to request a break. 
 SFISA-7353 card's circuit board design to ensure high isolation voltage, the input and output signals, power lines, ground in a physical location to connect with the computer system corresponding pull enough distance to ensure the isolation voltage of greater than 1000 volts . 
 SFISA-7353 card is easy to install, simple programming. Simply use the interface card into any PC ISA bus slot. The input and output signals on the card are 37-pin D-type socket and the external device signal, the power connection.
