Advantech 8 Channel Isolated Digital Input and 8 Channel Form C Relay Output USB Module

The USB-4761 is a relay actuator and digital input module which can communicate to your host computer or control system though USB.

The USB-4761 provides 8 optically isolated digital inputs with protection up to 2500V DC, which is ideal for collecting digital inputs in electronically noisy industrial environments.

The USB-4761 also includes 8 Form C relay actuators for serving as an on/off control device or a small power switch. For easy monitoring the USB-4761 is also equipped with individual red LED lights to indicate the relay’s on/off status.

The USB-4761 digital input channels featured a rugged isolated protection system which is ideal for industrial, lab and machinery applications.

The built-in isolation can withstand voltage spikes of up to 2500V DC, protecting your host system from harm. If connected to an external input power source with surge protection, the USB-4761 can offer up to 2000V DC ESD protection too.

Impulse can supply the USB-4761 on its own or paired with one of our embedded systems or boards.
