SST-DN3-PCI-2 DSQC658 DeviceNet PCI Communication Card in stock

SST-DN3-PCI-2 (ABB part number DSQC658) is a dual-channel DeviceNet PCI interface card developed by SST (Molex Woodhead). It is widely installed inside ABB IRC5 robot controllers to handle real-time DeviceNet fieldbus communication between robot mainboard and field peripherals.

This card adopts on-board 32-bit RISC co-processor to independently process DeviceNet protocol and reduce host CPU load. It provides galvanic isolation between PCI bus and DeviceNet network to protect the controller from surge and ground loop interference. It is widely used as spare replacement part for ABB IRC5 robot cabinet maintenance and retrofit projects.
