Universal Input Micro PLC Reference Design Board

The MAXREFDES67# reference design is a complete universal analog input for industrial applications. This unique 24-bit front-end accepts bipolar voltage and current, resistance temperature detector (RTD) and thermocouple (TC) inputs. Built in Maxim Integrated’s ultra-small Micro PLC form factor, the MAXREFDES67# performs with a effective resolution up to 22.3 bits with temperature error as low as ±0.1% across a range of -40°C to 150°C.
