Frequently Asked Questions
What's ±10V input used for?
Bipolar signals: servo drive command (±10V = forward/reverse), valve position (±10V = open/close), bidirectional control signals.
Can I use this for unipolar 0-10V signals?
Yes, ±10V input accepts 0-10V signals. 0V = mid-scale, 10V = full positive. Configure scaling in controller for 0-10V range.
What's the input impedance?
1MΩ for voltage inputs. High impedance minimizes loading on signal source. Suitable for most industrial transmitters.
Is channel isolation important?
Yes, channel-to-channel isolation prevents ground loops and noise coupling between channels. Essential for accurate measurements in noisy environments.
