FAQ

Q: What sensor types does this module support?
A: It supports RTD (Resistance Temperature Detector) and general resistance measurements across 8 input channels.

Q: What terminal block do I need?
A: Use a rotary-keyed terminal block set to position C3.

Q: Can I remove this module while the system is running?
A: Field power must be removed before module removal. System power must be de-energized for safe insertion or removal.

Installation Guidelines

1. Set the terminal block key to C3.
2. Install the card into an S-Series carrier slot.
3. Connect RTD or resistance sensor wiring per the DeltaV wiring manual.
4. For "nL" installations, an I/O loop assessment is required per hazardous-area guidelines.

Selection Tips

• Choose KJ3225X1-BK1 when you need RTD or resistance temperature measurement in DeltaV S-Series.
• Verify your sensor type (2-wire, 3-wire, or 4-wire RTD) is supported by this module revision.
• Confirm hazardous-area certification markings for your region.
