Frequently Asked Questions
Q1: Can I use both channels for different devices?
A1: Yes, each channel works independently with different devices.
Q2: What wiring problems does it detect?
A2: It finds both broken wires (open circuit) and shorted wires.
Q3: Does it work with non-HART devices?
A3: Yes, it works perfectly as a standard 4-20mA isolator for any device.
Q4: What is the advantage of two channels?
A4: It saves space and cost compared to using two single-channel units.
Q5: How much power does it need?
A5: It uses only 70mA at 24V, making it energy efficient.
