Application-Specific FAQ
Q: Can the FB900 8N-4*4NN5/A1-F801/Y accept a 4–20 mA pressure transmitter input?
A: Yes. The “4” in the input code position indicates analog current input compatibility. Verify the full option code against the RKC FB900 instruction manual for your specific wiring diagram.
Q: Does this unit support Modbus RTU communication?
A: The /Y suffix in the model code indicates the communication option. Please confirm against the RKC option table or contact us – we can decode the full model string for your application.
Q: Is this a direct replacement for an existing FB900 unit on my line?
A: Yes, provided the full model code matches. The FB900 series uses a standardized panel cutout (48×48 mm or 96×48 mm depending on variant) and identical terminal layout within the same code family.
Q: Can Konmask provide a Certificate of Conformance?
A: Yes. A CoC is available upon request for all units. Please note this in your order comments or email us after purchase.
Q: What is the warranty period?
A: We offer a 12-month warranty against manufacturing defects from the date of shipment, consistent with RKC’s standard warranty policy.
