Expert FAQs & Selection Guide
What is the purpose of the ‘wetting voltage’?
- Wetting voltage applies a small voltage across field contacts. This prevents corrosion and ensures a clean signal from switches and sensors.
Can this module be used in hazardous areas?
- Yes, the galvanic isolation per EN 60079-11 makes it suitable for use in IS (Intrinsically Safe) applications when properly installed.
How do I interpret the fault detection resistances?
- A reading below 200Ω indicates a short circuit. Between 360Ω and 19kΩ is a good circuit. Above 40kΩ suggests an open wire or failed device.
What type of input signals can it accept?
- It accepts standard dry contact signals (like from a push button) or solid-state switches that can handle the wetting current.
Why choose a CHARM module over a standard input card?
- CHARM modules offer superior diagnostics, isolation, and flexibility. They simplify maintenance and increase system availability in critical processes.

We ordered the SE4305T01 Digital Input CHARM for a manufacturing line control retrofit. The module was brand new and shipped quickly, which helped us stay on schedule. After installation, all discrete input signals were clean and stable, even in a high-noise environment. It integrated seamlessly with our existing DeltaV architecture. The seller provided professional communication and accurate documentation support. This CHARM module has been running 24/7 with zero faults. Great experience overall and would purchase again for future I/O expansions.
