Product Details:

INTERFACE PCI-2702C is a non-isolated high-speed PCI TTL digital input output board, and this ttl digital i/o board comes with 64 channels of TTL input and output, supporting handshake transfer, external interrupt signal input and external reset function, with built-in interval timer for timing control. It adopts common terminal design, input uses Schmitt trigger circuit, output is open collector with pull-up resistor, suitable for stable digital signal interaction with peripheral test fixtures and logic devices. It is widely used for electronic component functional test, fixture signal switching, production sequence control, laboratory logic verification, automated sorting equipment and legacy industrial control system renovation. Engineers can use the supporting driver library to configure handshake timing, interrupt trigger and timer parameters, which realizes reliable high speed handshake control for industrial and laboratory test applications.

Key specifications and parameters: 64 TTL digital I/O channels, non-isolated design, compatible with 5V TTL logic level. It supports hardware handshake signal, external interrupt input, external reset input and output. Onboard interval timer can generate periodic timing signals. It uses standard PCI bus, powered by PCI slot +5V supply. The connector adopts SCSI type interface for connecting external terminal boards and signal cables. The operating temperature range is 0 ℃ to 55 ℃, storage temperature -20 ℃ to 70 ℃, 10%–90% non-condensing humidity. It supports simultaneous latch capture of all input channels triggered by external strobe signal, which helps synchronous sampling of multi-point digital status. Status indicators help technicians check bus and signal status during commissioning and troubleshooting.

This interval timer digital control board is an end-of-life legacy hardware. We supply fully inspected and tested refurbished units for replacement and maintenance of old digital control and test systems. It can cooperate with relay terminal modules, signal conditioners and DAQ acquisition cards to build comprehensive stimulus-response test platforms. It is widely adopted in electronics manufacturing test stations, university automation teaching labs, packaging equipment control and legacy ATE systems. As a compact high-density TTL digital board, it provides stable handshake and interrupt digital control for long-running test and automation projects.
