Yokogawa RCCF31-AH2M/KF2/BG/X1/IE1 Remote Field Mount Converter

Configured for high-precision mass flow and density measurement in process automation environments, the Yokogawa RCCF31-AH2M/KF2/BG/X1/IE1 (RCCF31 Remote Field Mount Converter) provides direct physical/electrical execution. This field-mountable signal processing unit interfaces with ROTAMASS Coriolis flow sensor detectors, processing primary raw sensor signals into digitized mass flow, volume flow, fluid density, and process temperature data outputs. Operating on 90-250 V AC power at 47/63 Hz with a power consumption limit of 10 W, the assembly delivers dual analog outputs alongside HART signal modulation across process automation loops.

4-20 mA HART Loop Protocol & Fieldbus Connectivity

The RCCF31-AH2M/KF2/BG/X1/IE1 incorporates a dedicated 4-20 mA HART loop protocol physical layer alongside support for FOUNDATION Fieldbus and PROFIBUS digital field network communication. The converter overlays digital Frequency-Shift Keying (FSK) diagnostic data onto primary 4-20 mA analog output channels, facilitating real-time telemetry transfer for process mass flow, secondary density metrics, and sensor diagnostic flags without interrupting primary current loop signals. Passive status outputs rated to 30 V DC, 200 mA provide direct pulse or discrete alarms to host DCS interface cards. Integrated cold junction compensation (CJC) algorithms process RTD resistance readings from the remote sensor tube to ensure temperature-corrected density calculations across thermal swings.

Frequently Asked Questions

Q: What conduit connections are provided on the field enclosure?

A: The converter enclosure features ANSI 1/2 in NPT female threaded cable entries designed for explosion-proof conduit engagement or certified Ex d cable glands.

Q: How does the unit isolate passive pulse and analog outputs from external loop noise?

A: Internal galvanic isolation barriers separate field output terminals from the main power supply and digital signal processing circuitry, mitigating ground loop interference and maintaining output stability under high electrical noise conditions.

Q: Is the high-visibility LCD operable in low-ambient temperature field installations?

A: The integrated multilingual LCD module maintains clear visual refresh rates across operating ambient temperatures down to -20 deg C without degradation of process variable readability.

Field Installation Guidelines

Conduit Engagement & Sealing: Thread explosion-proof conduit entries to ensure a minimum of 5 full NPT threads engagement. Apply approved non-hardening thread sealant to maintain IP66/IP67 ingress ratings and flameproof integrity.
Shielding & Grounding: Connect overall signal cable shielding to the designated internal ground lug. Fasten an external copper bonding conductor to the outer enclosure grounding terminal, verifying low-impedance ground reference to plant earth.
Cable Strain Relief: Ensure all multi-core sensor interconnecting cables are secured using appropriate cable clamps or glands before entering the terminal compartment to eliminate mechanical stress on internal terminal blocks.
Wiring Clearance: Maintain strict physical segregation between 90-250 V AC main power wiring and low-voltage 4-20 mA/HART signal conductors within field junction boxes to prevent capacitive noise coupling.
