Important Technical Questions
- What is the difference between voltage ranges?
You can choose ±10V for bipolar control, 0-10V for unipolar, or 1-5V for live zero signals. - How do I select the power source?
Use jumper J4 to choose between backplane power (RACK) or external 24V DC power (EXT). - Can I set different ranges per channel?
Yes. Each channel can be independently configured for any of the five voltage ranges. - What is the over-range capability?
It can output up to ±10.25V, providing 2.5% over-range for special applications. - How does it handle fault conditions?
You can set output behavior on faults: reset to zero, hold last value, or jump to a preset value.
