Frequently Asked Questions
The module supports 0–10 V DC by default; it can be configured for 0–5 V ranges via software registers.
Use your Modbus RTU master to write scaling parameters to the configuration registers; settings are stored in non-volatile memory.
Yes—by installing a 250 Ω shunt resistor across each input, 4–20 mA loops convert to 1–5 V for direct measurement.
Analog input values are available in Input Registers starting at address 30001; consult the datasheet for the exact register map.
No—power down the RS-485 network before inserting or removing the IOS/M08IVX-D1 to avoid communication errors.
