          PRODUCT DESCRIPTION

          SNT411-5F S2 Long-Range Optical ESB Master

          Yokogawa SNT411-5F S2 is the master module for the long-range ProSafe-RS optical ESB connection. It extends the electrical ESB interface to a matched SNT511 or an explicitly supported S2EN501 endpoint over the optical path. The SNT411/SNT511 specification supports star and chain layouts on Vnet/IP-based systems.

          The family covers a total optical distance of 5 to 50 km across no more than two stages and lists 0.5 A current consumption. The link requires 3 to 4 dB optical attenuation; when cable attenuation is below 3 dB, the specification calls for a 3 dB attenuator. SENG and SCS R1.03 or later are required, and the F endpoint pairing must be maintained.

          SYSTEM & REPLACEMENT CHECK

          Information needed before ordering

          Three direct checks to secure your system integration and minimize ordering risks.

          Information

          System integration Replacement check Manuals & support
          SYSTEM INTEGRATION

          Integrate SNT411-5F S2 within ProSafe-RS optical ESB

          Connect the SNT411 master to SEC401, SEC402 or the applicable SSB401 electrical ESB interface. Select the remote F-version SNT511 or the specific S2EN501 optical option from the manufacturer combination table; an arbitrary optical endpoint is not sufficient.
          Calculate the entire two-stage optical route within the 5 to 50 km range. The specified optical attenuation is 3 to 4 dB; use the documented attenuator arrangement if cable attenuation is too low. The 1 to 2 dB exception applies only when both endpoint styles are S1, not to this S2 master.
          Use SENG and SCS R1.03 or later, preserve odd/even slots for duplex bus 1 and bus 2, and apply the SNT10D temperature clearances. ALR111 and ALR121 cannot be installed in an SNB10D located more than 5 km away through these optical repeaters.

          Features:

          • Current consumption: 0.5 A
          • Connection topologies: Star and chain
          • ProSafe-RS optical ESB
          Use SNT411-5F S2 only within the documented ProSafe-RS optical ESB arrangement and applicable installation instructions.
          INTERCHANGEABILITY

          Replace SNT411-5F S2 within ProSafe-RS optical ESB

          Match the complete SNT411-5F S2 identification, master role and F optical pairing to the removed module. Record the far endpoint and route length; the short-range SNT401 family and the SNT411 long-range family have different distance and optical-loss requirements.
          Label the electrical ESB cable, optical paths and attenuators before disconnection. Preserve the connector termination option and duplex slot assignment, and inspect optical end faces without changing the designed attenuation arrangement.
          After exchange, validate both ESB paths, remote-node availability and the route attenuation under the approved maintenance procedure. Confirm the installed software revision and the restriction on serial modules in distant SNB10D nodes before returning the path to service.

          Features:

          • SNT411-5F S2 complete suffix
          • Distant-node serial restriction: No ALR111/ALR121 on SNB10D beyond 5 km
          • Master/slave role and installed optical paths retained
          Use SNT411-5F S2 only within the documented ProSafe-RS optical ESB arrangement and applicable installation instructions.

          FREQUENTLY ASKED QUESTIONS

          Questions buyers ask about SNT411-5F S2

          Direct answers about identity, compatibility, stock, warranty, payment and shipping.

          • What optical loss does SNT411-5F S2 require?

            The SNT411/SNT511 specification applicable to SNT411-5F S2 requires 3 to 4 dB optical attenuation between the supported endpoints.

          • Does the S1 attenuator exception apply to SNT411-5F S2?

            No. The 1 to 2 dB exception requires both endpoints to have style S1. SNT411-5F S2 is style S2, so use the general documented loss requirement.

          • What happens when the cable loss for SNT411-5F S2 is below 3 dB?

            For SNT411-5F S2, Yokogawa specifies a 3 dB attenuator when attenuation from the optical cable is less than 3 dB.

          • Can SNT411-5F S2 operate on an ordinary Vnet arrangement?

            The long-range ESB optical transport function of SNT411-5F S2 is specified for Vnet/IP only, with SENG and SCS R1.03 or later.

          • Is the 50 km allowance for SNT411-5F S2 per stage?

            No. The 5 to 50 km range applicable to SNT411-5F S2 is the total across a maximum of two connecting stages.

          • Can a distant SNB10D behind SNT411-5F S2 contain ALR121?

            ALR111 and ALR121 cannot be mounted in an SNB10D more than 5 km away through the optical ESB repeater path using SNT411-5F S2.

          • What route information helps a distributor quote SNT411-5F S2?

            Supply SNT411-5F S2, the far-end module and optical suffix, total cable route, attenuator requirement and connector-unit option. Those details prevent a short-range or wrong-pairing offer.

          • Should attenuators be assumed in the supplied scope of SNT411-5F S2?

            No. A quote for SNT411-5F S2 should identify any attenuator, optical cable or ESB connector unit separately rather than treating them as automatic module accessories.
