Frequently Asked Questions (FAQ)
- Can I mix voltage and current inputs on the same module?
Yes. Each of the 16 inputs is individually configurable for V or mA. - How do I activate the shunt resistor for mA inputs?
Use the DIP switches on the module to enable the integrated 250Ω resistor per channel. - What does the red LED indicate?
A red LED means a diagnostic condition exists – check calibration or supply voltage. - Is field calibration better than factory calibration?
Field calibration achieves ±0.05% accuracy vs. ±0.1% factory, but requires proper reference conditions. - What terminal block is required?
This module requires a Euro style 36-terminal terminal block (not included).
