          PRODUCT DESCRIPTION

          SNT401-53 S1 Optical ESB Master Module

          Yokogawa SNT401-53 S1 provides the master end of a ProSafe-RS optical ESB connection. Its electrical side joins the safety control or node ESB interface, while its optical side extends that bus to a matched slave. Star and chain connections are supported, including duplex configurations with separate bus 1 and bus 2 modules.

          The manufacturer specifies 0.5 A consumption, a maximum of two optical stages and a standard combined path up to 5 km for SNT401/SNT501. The final 3 suffix belongs to the ISA G3, -20 to 70 C maintenance version, and the first 5 suffix denotes no explosion protection. A 10 km combined path is conditional on the listed Vnet/IP revision.

          SNT401-53 S1 ProSafe-RS optical ESB Optical ESB Master Module
          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 SNT401-53 S1 within ProSafe-RS optical ESB

          Use the SNT401-53 master at the electrical ESB origin and select a final 3 SNT501 slave for the optical endpoint. An ESB connector unit without termination and one with termination are separately described by /CU1N and /CU1T; select the version appropriate to the bus end.
          A duplex installation uses two adjacent repeater positions. Assign bus 1 to the odd position and bus 2 to the even position, and keep both module suffixes identical. This arrangement is separate from the choice of star or chain topology.
          The listed 0.5 A consumption must be included in the host power budget. Apply the 5 km combined-distance rule unless the documented Vnet/IP R1.03-or-later extension is met, and retain the special SNT10D clearances when the ambient temperature reaches 60 to 70 C.

          Features:

          • Current consumption: 0.5 A
          • Connection topologies: Star and chain
          • ProSafe-RS optical ESB
          Use SNT401-53 S1 only within the documented ProSafe-RS optical ESB arrangement and applicable installation instructions.
          INTERCHANGEABILITY

          Replace SNT401-53 S1 within ProSafe-RS optical ESB

          Compare the -53 suffix with the removed master before selecting the replacement. It identifies the no-explosion-protection, G3 and extended-temperature maintenance version; hazardous-area suitability must not be inferred from another SNT401 approval suffix.
          Identify the matching slave and the existing connector-unit option, then label the two ESB paths independently. Preserve the odd/even mounting order and the original termination arrangement so that the replacement does not change the electrical bus layout.
          Restore the optical paths under the site maintenance procedure and verify remote-node availability on each redundant path. Review connector condition, optical cable routing and the installed system revision whenever the link has been changed or extended.

          Features:

          • SNT401-53 S1 complete suffix
          • Environmental suffix 3: ISA Standard G3
          • Master/slave role and installed optical paths retained
          Use SNT401-53 S1 only within the documented ProSafe-RS optical ESB arrangement and applicable installation instructions.

          FREQUENTLY ASKED QUESTIONS

          Questions buyers ask about SNT401-53 S1

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

          • Is SNT401-53 S1 the explosion-protected version?

            No. In SNT401-53 S1, the first suffix 5 is defined as no explosion protection. An E suffix is a different selection and cannot be assumed from the family name.

          • What does the final 3 mean in SNT401-53 S1?

            For SNT401-53 S1, Yokogawa identifies suffix 3 as the ISA Standard G3 and -20 to 70 C version intended for maintenance.

          • Can SNT401-53 S1 pair with an SNT501-F?

            The published table pairs the final 3 master SNT401-53 S1 with a final 3 slave. An F slave belongs to the separately listed F combination.

          • How is the load of SNT401-53 S1 budgeted?

            The SNT401/SNT501 specification gives 0.5 A current consumption for SNT401-53 S1; account for each installed module, including both modules in a duplex pair.

          • Which host interfaces accept the electrical side of SNT401-53 S1?

            The SNT401-53 S1 master connects through electrical ESB cable to SEC401, SEC402 or the applicable SSB401 node interface.

          • What spacing applies to SNT401-53 S1 at 60 to 70 C?

            On SNT10D, the mounting rules for SNT401-53 S1 require two free slots beside the power supply and two free slots between repeater sets at that temperature.

          • Can a quotation combine SNT401-53 S1 with an unspecified master?

            The order should identify SNT401-53 S1 and every required connector option explicitly. A family-only SNT401 quotation does not establish the same approval, temperature or termination configuration.

          • What evidence should accompany a replacement request for SNT401-53 S1?

            Provide the SNT401-53 S1 label, matching slave designation, connector-unit option and required quantity. The distributor can then separate the module from any termination accessory in the quotation.
