Frequently Asked Questions
Is Modbus RTU included as a standard output on the TX4S-B4R?
The available product information identifies Modbus RTU as an option output. It should therefore not be assumed to be a standard output without confirming the required configuration before ordering.
What should be checked when selecting a sensor for the TX4S-B4R?
Confirm that the sensor matches one of the supported input types: K, J, T, R, S, or L thermocouple, or DPt100Ω or Cu50Ω RTD. The required sensor type should be verified against these supported inputs before selection.
Does the IP50 rating apply to the entire TX4S-B4R enclosure?
No. The specified IP50 protection applies to the front panel. It should not be interpreted as an IP50 rating for the complete unit.
