Frequently Asked Questions (FAQs):

Q1: What does "isolating transmitter" mean?

A1: An "isolating transmitter" (or galvanic isolation) means that there is no direct electrical connection between the input (where your sensor connects) and the output (where the 4-20mA signal goes). This electrical separation prevents ground loops, protects equipment from voltage surges, and eliminates noise from the signal, ensuring much more accurate and reliable readings.

Q2: What is the benefit of a "2-wire 4-20mA" output?

A2: A 2-wire 4-20mA output means that the transmitter draws its power directly from the current loop itself. This simplifies wiring significantly as only two wires are needed for both power and signal transmission, reducing cabling costs and installation complexity compared to 3-wire or 4-wire systems.

Q3: What types of sensors can I connect to the Novus TxIsoUSB?

A3: This is a universal input transmitter, meaning it's highly versatile. You can connect various types of temperature sensors like Thermocouples (J, K, T, E, N, R, S, B) and RTDs (Pt100, Pt500, Pt1000). It also accepts direct millivolt (mV) and voltage (V) inputs, and can convert current (mA) signals with an external shunt resistor.

Q4: How do I configure the Novus TxIsoUSB transmitter?

A4: Configuration is very easy! You simply connect the transmitter to your computer's USB port using a standard micro USB cable. Then, you use the free Novus TxConfig II software to select your sensor type, input range, and output settings. No external power supply is needed during the configuration process.

Q5: Is this transmitter suitable for hazardous areas?

A5: While the TxIsoUSB offers isolation and is robust, it is not intrinsically safe (Ex-certified) for use in hazardous (explosive) atmospheres. If you require a transmitter for such environments, please ensure you select one with appropriate Ex certifications.
