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 V
DC
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 V
DC
,
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 V
DC
ESD
(Electrostatic Discharge) protection. Even with an input voltage rising up to 70 V
DC
, the PCI-1761 can still manage to work properly, albeit for only a short period of time.
