Frequently Asked Questions
Q1: What is a smart transmitter?
A1: It is a transmitter that can send both 4-20mA analog signals and digital data for setup and diagnostics.
Q2: Can both outputs be used for digital communication?
A2: No, only Output 1 supports digital communication. Output 2 is for analog signals only.
Q3: What types of transmitters can it power?
A3: It works with pressure, temperature, level, and any other 2-wire 4-20mA transmitters.
Q4: How much voltage does it provide to the transmitter?
A4: It provides a minimum of 15V at 20mA to power the transmitter properly.
Q5: What is the advantage of two outputs?
A5: You can send the same signal to two different devices, like a controller and a recorder.
