Designers now have a way to reduce power, system cost, and size for programmable logic controller (PLC) digital-input subsystems, with the Corona (MAXREFDES12#) reference design by Maxim Integrated Products (Munich, Germany). This design reduces isolated channels and leverages analog integration for industrial control and automation applications. Features include:
- Analog integration: Reduces isolation channels to four while Maxim’s digital isolator eliminates the need for optoisolators.
- Lower power: Best-in-class power consumption; uses 16% less power than the traditional design approach.
- Lower cost: Uses 38 fewer parts than a traditional design to create a less expensive integrated solution.
- Smaller size: Provides 51% fewer components than a traditional design.
