Timer/Counter interrupt capability Supports both contact Keeps port setting state after system reset
Introduction
PCI-1751 48-bit digital card based bus. bits divided into 8-bit ports users configure each port input output software. PCI-1751 also provides event counter 16-bit timers, which cascaded become 32-bit timer.
Digital Input
Logic level Logic level 5.25
Programmable timer/counter
Frequency range: Counters:Two 16-bit counters 32-bit counter 16-bit event counter
Fulfilling True Requirements Industrial Applications
With practical functions, PCI-1751 fulfills true requirements industrial applications. When system reset, (power shut off), PCI-1751 either retain last port setting output value, reset default configuration, depending jumper settings. This function protects system from wrong operations during unexpected system resets. Additionally, PCI-1751 supports both contacts that easily interface with other devices.
General
Power consumption: (typical) (max.) Operating temperature: +70° 158° Storage temperature: +80° 176° Operating humidity: non-condensing (refer 68-2-3) Connectors: 68-pin SCSI-II female connector Dimensions: (6.9" 3.9")
Interrupt Handling Capability
lines each port three counter outputs (Timer Counter connected interrupt circuitry. interrupt request signals generated same time software service request signals ISR. Moreover, connector output digital signal simultaneously with card generating interrupt, users utilize this function trigger external devices with interrupt.
