Frequently Asked Questions (FAQ)
Q: What signal ranges does this CHARM support?
A: 4-20 mA (with or without HART) and 0-20 mA.
Q: Do I need to calibrate this module?
A: No. The CHARM requires no calibration.
Q: What is the maximum load for field power?
A: 750 Ω load at 15V DC supply, 20 mA.
Q: Which DeltaV controller versions support this CHARM?
A: v11.3.1+ for SD Plus/SX/SQ; v14.3+ for MD Plus/MQ/MX/PK.
Q: Is this CHARM suitable for hazardous areas?
A: Yes. It has FM, ATEX, and IEC-Ex Class I Div 2 / Zone 2 approvals.
Experience-Based Q&A
Q: We have slow HART update rates on some devices. What can we do?
A: Reduce HART device polling or use dedicated HART multiplexers for busy networks.
Q: Can we mix CHARM types on the same carrier?
A: Yes. CHARM carriers support mixed I/O types including AI, AO, DI, DO.
Selection Guide
- Choose SE4304T01 for 4-20 mA analog output with HART capability
- Select 0-20 mA option if your device requires that range
- Verify controller compatibility with your DeltaV software version
- Check controller Time Utilization before assigning multiple CHARMs
- Account for 42 mA power draw per CHARM at 24V DC
- For non-HART applications, this CHARM still works as standard AO
