Frequently Asked Questions
- Can I mix RTD and POT on different channels?
- Yes. Each channel (CH1 to CH16) can select RTD or POT independently via software.
- What cable do I need for connection?
- Use Yokogawa KS8 or AKB335 dedicated cable. Terminal boards MRT, TERT, or AER4D are compatible.
- Does it support 2-wire RTD?
- No. This module only supports 3-wire Pt100 RTD. Use 3-wire sensors for best accuracy.
- What is the burn-out detection time?
- 60 seconds. You can set it to UP or DOWN scale. All channels share the same setting.
- How accurate is the potentiometer measurement?
- ±0.2% of full scale. Ensure span resistance is ≥50% of total resistance for best linearity.
- Can I use this in dual-redundant systems?
- Yes. The AAR145 supports dual-redundant configurations for critical applications.
Selection Guide
- Choose AAR145-S00 if: you need 16 channels with mixed RTD and POT inputs.
- For RTD only: consider AAR181 (16 ch, Pt100 only).
- For thermocouples: select AAR146.
- Check your cable: KS8 or AKB335 is required.
- Dual-redundant? This module is ready for it.
