Frequently Asked Questions
What is the advantage of bipolar inputs?
Bipolar inputs can measure both positive and negative signals, essential for applications like motor position, bidirectional flow, or differential pressure measurements.
How does the transmitter supply work?
The module distributes external transmitter power to each channel, simplifying connection for 2-wire transmitters without additional wiring.
What protection is provided for accidental high voltage?
5W current sense resistors provide temporary protection against accidental 24V connections, safeguarding one channel at a time during wiring errors.
