Si8380PF-IU

Si8380PF-IU Eight Channel 24 V Digital Isolator

The Si8380PF-IU provides eight channels of 24 V digital field interface in a single compact QSOP package to either sinking or sourcing inputs with integrated safety rated isolation. In combination with a few external components, this provides compliance to IEC 61131-2 switch types 1, 2, or 3. The input interface is based on our ground breaking CMOS based LED emulator technology which enables the bipolar capability (sinking or sourcing inputs) with no power supply required on the field side. The output interface to the controller allows for low power operation with 2.25 V operation capability.

Evaluation Kits

Si838xISO-KIT

Si838x PLC Input Isolator Evaluation Kit

The Si838x evaluation board allows designers to quickly evaluate this family of products. The 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 24 V digital logic signals into the test-points labeled “EXT” or 2 - 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.
