8-ch digital input IC with integrated 500VRMS isolation, channel resolved wire-break diagnostics and 3-level VBB monitoring for industrial automation. ISOFACE™ ISO1I813T is a high featured system solution for IEC 61131-2 compliant digital inputs in industrial automation with detailed diagnostic feedback per channel. Its 8 channels offer configurable sensor level detection for Type 1, 2 and 3 sensors and precisely regulate the sensor current to reduce power dissipation effectively. The sensor data captured by the IC is reliably transferred to the µC domain via integrated galvanic isolation.
