Selection Guide
Use the following criteria to confirm the 3500/61E 285694-02 is the correct module for your application:
- Measurement type: Do you need dynamic (AC) pressure measurement? → 3500/61E ✓
- Transducer type: ICP or charge-mode dynamic pressure sensor? → 3500/61E ✓
- Channel count: 1–2 channels required? → 3500/61E ✓ (for 4+ channels, consider dual-module configuration)
- Rack slot availability: Single slot available in 3500 rack? → 3500/61E ✓
- Static pressure only: If only static/process pressure is needed → consider 3500/60 Process Variable Monitor instead
- New installation: For greenfield projects, evaluate Emerson CSI 6500 for advanced IIoT capabilities

Replacement & Compatibility FAQ
Q: Can I use the 285694-01 sub-revision in place of the 285694-02?
A: In most cases yes, but verify with your System 1 software version and rack firmware. Contact Konmask for a compatibility check.
Q: Is the 3500/61E compatible with third-party dynamic pressure sensors?
A: The module is optimized for Bently Nevada-approved ICP transducers. Third-party sensors may work but require validation against the module’s input impedance and signal conditioning specs.
Q: What is the difference between the 3500/61 and 3500/61E?
A: The “E” revision introduced enhanced diagnostics, improved EMC performance, and expanded software configurability. The 3500/61E is the recommended current standard.
Q: Can Konmask supply a tested spare for emergency replacement?
A: Yes. We maintain stock of tested units for rapid dispatch. Contact us directly for emergency sourcing.
Q: Do you provide installation support?
A: We provide technical documentation and remote guidance. On-site commissioning support can be arranged through our partner network.
