FAQ – Frequently Asked Questions

• What is the maximum number of shorted transmitter supplies allowed?
• Up to 12 supplies can be shorted simultaneously for less than 3 seconds.
• What happens if I short more than 12 supplies?
• All transmitter supplies turn off after 3 seconds. They restart automatically if the overload clears within 30 seconds.
• Can I use this module with a 2-wire transmitter?
• Yes. Each channel provides a 26.5V DC transmitter supply, max 30 mA.
• Is the module hot-swappable?
• No. Refer to the HIMax system manual for replacement procedures.
• What is the settling time for a changing input signal?
• 15 ms to reach 99% of the final process value.
• Does the module work with active (loop-powered) sensors?
• Yes, as long as the total loop load stays ≤750 Ω at 22.5 mA.

Expert Tips & Selection Guide

• Choose this module if you need 32 channels with individual transmitter supplies.
• Use for SIL 3 safety loops where common ground AI- is acceptable.
• For isolated channels, consider HIMA X-AI modules with per-channel isolation.
• Do not exceed 12 shorted transmitter supplies to avoid global shutdown.
• Pair with 11 mm Proximity Probes for vibration or position monitoring.
• If your transmitter draws >30 mA, use an external power supply.
• Verify total wire resistance keeps load ≤750 Ω at 22.5 mA.
