Relay PCI-1761 – Advantech

8-ch relay and 8-ch isolated digital input PCI card.
The PCI-1761 relay actuator and isolated D/I card is an add-on card for the PCI bus.
It provides 8 optically-isolated digital inputs with isolation protection of 3750 VDC for collecting digital inputs in noisy environments and 8 relay actuators for serving as on/off control devices or small power switches.
The PCI-1761’s eight optically-isolated digital input channels are ideal for digital input in noisy environments or with floating potentials.

  • 8 opto-isolated digital input channels;
  • 8 relay actuator output channels;
  • LED indicators to show activated relays.
  • For easy monitoring, each relay is equipped with one red LED to show its on/off status;
  • The PCI-1761 digital input channels feature a rugged isolation protection for industrial, lab and machinery automation applications. If connected to an external input source with surge-protection, the PCI-1761 can offer up to a maximum of 2000 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;
  • When the system has undergone a hot reset (i.e. without turning off the system power), the PCI-1761 can either retain output values of each channel, or return to its default confi guration as open status, depending on its onboard jumper setting. This function protects the system from unwanted operations during unexpected system resets.
  • All kind of industry that uses or develops test bench machine tools.
