PCI-1761 8-ch Relay and 8-ch Isolated Digital Input PCI Card Features ISA-Compatible with PCL-725 8 relay output channels and 8 isolated digital input channels LED indicators to show activated relays 4 Form C and 4 Form A type relay output channels Male DB37 matching connector included Output status readback Retained relay output values when hot system reset High-voltage isolation on input channels (3,750 VDC) High ESD protection (2,000 VDC) High over-voltage protection (70 VDC) Wide input range (10 ~ 50 VDC) Interrupt handling capability BoardID™ switch RoHS COMPLIANT 2002/95/EC Introduction The PCI-1761 relay actuator and isolated DI card is an add-on card for the PCI bus. It provides 8 optically-isolated digital inputs with isolation protection of 3,750 VDC for collecting digital inputs in noisy environments and 8 relay actuators for serving as on/off control devices or small power switches. For easy monitoring, each relay is equipped with one red LED to show its on/off status. The PCI-1761’s eight optically-isolated digital input channels are ideal for digital input in noisy environments or with floating potentials. The PCI-1761 digital input channels feature a rugged isolation protection for industrial, lab and machinery automation applications. It durably withstands voltage up to 3,750 VDC, protecting your host system from any incidental harms. If connected to an external input source with surge-protection, the PCI-1761 can offer up to a maximum of 2,000 VDC ESD (Electrostatic Discharge) protection. Even with an input voltage rising up to 70 VDC, the PCI-1761 can still manage to work properly, albeit for only a short period of time.
