Si838x PLC Input Isolator Evaluation Kit


The Si838x evaluation board allows designers to evaluate Silicon Lab's Si838x family of PLC input isolators. The Si838xISO-EVB is populated with a Si8384P and three different input networks, each representing a recommendation derived from the respective IEC 61131-2 digital input types at 24 V dc. The Si838xISO-EVB allows designers to quickly evaluate the Si8384P’s functionality and capabilities by driving either 24V digital logic signals into the test-points labeled “EXT” or 2 V - 5 V signals into the remaining test-points. The board facilitates quick evaluation of the devices’ key parameters and also includes test points on each devices’ pins to accommodate direct connection to the designer’s end system.
