Selection Guide
Use the criteria below to confirm the RWF40.000A97 is the correct model for your application:
- Control type needed: Single-loop temperature or pressure → RWF40 ✅ | Dual-loop or cascade → consider RWF55 series
- Sensor type: Pt100 / Pt1000 / NTC / 0–10 V / 4–20 mA → RWF40.000A97 ✅
- Output requirement: On/off or 3-point stepping → RWF40.000A97 ✅ | Continuous modulating (0–10 V) → verify suffix variant
- Supply voltage: AC 100–240 V → RWF40.000A97 ✅ | DC 24 V → select RWF40.002 variant
- Panel cutout: 92 × 92 mm standard → RWF40 ✅
- Communication: Standalone (no bus) → RWF40.000A97 ✅ | LON/BACnet required → RWF55 + AZL module
