Frequently Asked Questions

Q: What is the maximum cable length?
A: 3 m shielded for EMC compliance. Absolute maximum is 10 m.
Q: Can I mix voltage and current inputs on the same module?
A: Yes. Each channel configures independently for voltage or current.
Q: Does it support remote I/O expansion?
A: Yes. Supports up to 7 expansion modules via the internal bus.
Q: What is the power supply requirement?
A: 24 Vdc nominal. Accepts 19.2…28.8 Vdc range.
Q: Should I choose voltage or current input for my application?
A: Use voltage for short distances. Use current for better noise immunity over longer runs.
Q: Is it compatible with older SoMachine software?
A: Yes. Supports SoMachine V4.3 and newer versions.
Q: How do I reduce noise on analog readings?
A: Use shielded cable with grounded shield. Keep cable length under 3 m. Separate from power cables.
Q: What is the typical scan time added to sampling?
A: Sampling takes 10 ms per channel plus one full scan cycle.
