PCI-1761
Introduction
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 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.
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 configuration
as open status, depending on its onboard jumper setting. This function protects the system from unwanted operations during unexpected system resets.
