5 Professional FAQs
- Can I mix 0-20mA and 4-20mA sensors on the same module?
- Yes. Configure each channel independently in HIMax engineering tool.
- What happens if more than 12 transmitter supplies short circuit?
- All 32 transmitter supplies turn off after 3 seconds. System auto-recovers within 30 seconds after fault clears.
- Do I need external resistors for current measurement?
- No. Each channel has built-in 200Ω shunt resistor.
- Is this module hot-swappable in HIMax system?
- Refer to HIMax system manual. Some configurations support hot swap. Contact us for details.
- What is the maximum cable length for 4-20mA signals?
- Keep total load (transmitter + cable) ≤750Ω at 22.5mA. For 1.5 mm² copper, max length approx. 1000m.
Selection Guide – Pick the Right HIMax Analog Input Module
- Step 1 – Channel count needed: X-AI3201 gives 32 channels. For fewer channels, consider X-AI1601 (16 channels).
- Step 2 – Signal type: This module handles 0/4-20mA only. For voltage signals (0-10V), choose X-AV series.
- Step 3 – Need transmitter supply? X-AI3201 includes supplies. For external powered transmitters, choose X-AI3201 without supply option.
- Step 4 – Safety level required: This module is SIL 3 / PL e. For lower safety needs, SIL 2 modules cost less.
- Pro tip: For fast-changing signals (under 15ms), use the 2ms sampling time. For stable temperature signals, use filtering in user program.
