MAXREFDES67#: Universal Input Micro PLC (MAXREFDES67)

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.

To enhance ease of use, the innovative system architecture switches all signals on board, meaning that the connector requires no jumpers or additional connections, regardless of the type of connection. In addition, the system features Maxim Integrated’s Beyond-the-Rails feature in all signal-chain elements. Beyond the Rails reduces the need for large power supplies, allowing each element to accept large input voltages while running from a low-voltage power rail.

The board features a micro USB connector for quick connection to a PC for evaluation. In addition, the board requires a 24V power supply, from a power supply or from the included AC/DC wall adapter.
