Advantech PCI-1760 Relay Actuator and Isolated Digital Input Card

The Advantech PCI-1760 is a PCI/PCIe relay actuator and isolated digital input card for industrial automation and real-time control. It combines 8 relay outputs with 8 galvanically isolated digital inputs, delivering 2,500 VDC isolation protection in hostile electrical environments. The card supports both dry-contact and wet-contact signaling, programmable digital filtering, and dual interrupt modes (pattern match and change-of-state detection). Two independent 16-bit event counters monitor digital inputs up to 500 Hz or 1 kHz, while 2 isolated PWM channels provide proportional control capability. All relay channels feature individual LED status indicators and operate within 5 ms switching time, supporting loads from 0.5 A @ 125 VAC through 1 A @ 30 VDC.
