A: The module has two output channels configured in a redundant setup.

Q3: What types of output signals can the VE4035S2B1 provide?
A: It supports 4–20 mA and 0–10 V analog signals.

Q4: Is the module optically isolated?
A: Yes, each output channel is optically isolated to protect against electrical noise and ground loops.

Q5: What is the accuracy of the VE4035S2B1?
A: The module offers an accuracy of ±0.25% of span over the specified temperature range.

Q6: What is the operating temperature range of the VE4035S2B1?
A: It operates reliably from –40°C up to +70°C, suitable for harsh industrial environments.

Q7: How is redundancy implemented in this module?
A: The two output channels work in a redundant configuration where one channel automatically takes over if the other fails, ensuring continuous signal output.

Q8: What are the physical dimensions and weight of the VE4035S2B1?
A: The module measures approximately 263 mm (height) × 58 mm (width) × 28 mm (depth) and weighs about 0.3 kg.

Q9: Can the output signal type be configured after installation?
A: Yes, the output signal type (4–20 mA or 0–10 V) can be configured per channel based on the application requirements.

Q10: How does the module handle power consumption?
A: It draws about 100 mA typically from the local 12 V bus, with a maximum of 150 mA, and up to 300 mA from the 24 V field power supply.
