Introduction
The USB-4761 is a relay actuator and isolated digital input module for USB bus. It provides 8 optically-isolated digital inputs with isolation protection of 2,500 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 USB-4761’s eight optically-isolated digital input channels are ideal for digital input in noisy environments or with floating potentials.
Rugged Protection
The USB-4761 digital input channels feature a rugged isolation protection for industrial, lab and machinery automation applications. It durably withstands voltage up to 2,500 V
DC
,
protecting your host system from any incidental harms. If connected to an external input source with surge-protection, the USB-4761 can offer up to a maximum of 2,000 V
DC
ESD
(Electrostatic Discharge) protection.
