Si8380P-IU Eight Channel 24 V Digital Isolator
The Si8380P-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 Silicon Labs’ 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.
