Description

This reference design is a four channel-to-channel, isolated 4–20 mA, current-loop analog input module. The design includes a short circuit, overcurrent, and overvoltage limit function for condition monitoring sensor and module applications. The major features of this analog input module include channel isolation, a multi-channel analog input module powered up by a single flyback converter using LM5180 device, a power supply to 2-wire transmitter and short-circuit protection circuit. This design can also support a four-channel analog input module.

Features

1 to 4 channel-to-channel isolated analog input moduleSupply for field transmitters with output power limitation (short limited to 25mA)Transmitter supply: 25 ±1V, IOUT < 25-mA peakInput protected against miss wiringUART interface 24b ΔΣADC to reduce BOM size and cost
