Circuit Centre – Process Control

p10_ProcessControl_thumb1

The microcontroller takes centre stage in the block diagram for a typical process-control application, and it is microcontrollers which are featured in the Application Spotlight section that follows. But the block diagram also highlights the many peripheral functions that support a process-control system, including analogue, communications and protection components, and these can all be found […]

Intersil – RS-485/RS-422 transceivers offer high ESD protection

p12_Intersil_thumb1

RS485 Intersil’s ISL3179E and ISL3180E are single transceivers which meet both the RS-485 and RS-422 standards for balanced communication. Each device has a low bus current of 220μA/-150μA, so it presents a 1/5 unit load to the RS-485 bus. This allows up to 160 transceivers to be present on the network without violating the RS-485 […]
