          PRODUCT DESCRIPTION

          SNT401-13 S1 Optical ESB Master Module

          Yokogawa SNT401-13 S1 is an optical ESB bus repeater master module for ProSafe-RS. It converts the electrical ESB connection from a safety control unit or safety node into an optical link, allowing separated nodes to remain connected through a supported star or chain arrangement. The SNT401 master works with the corresponding SNT501 slave rather than functioning as a general-purpose Ethernet converter.

          The SNT401/SNT501 specification lists 0.5 A current consumption and a maximum of two optical stages. Standard total transmission distance is up to 5 km; the 10 km two-stage allowance requires the documented Vnet/IP R1.03 or later arrangement. A duplex pair occupies consecutive slots, with bus 1 in the odd slot and bus 2 in the even slot.

          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 SNT401-13 S1 within ProSafe-RS optical ESB

          Connect the master-side electrical ESB cable to the applicable SEC401, SEC402 or SSB401 interface. The opposite optical endpoint must be the matching SNT501 type; the terminal digit 3 pairing is shown separately from the F pairing in the manufacturer selection table.
          Plan the optical path as one or two stages and calculate the total path rather than treating the distance allowance as a per-stage figure. The general SNT401/SNT501 limit is 5 km; the longer two-stage arrangement is conditional on the Vnet/IP revision stated in the specification.
          For duplex ESB transport, install the two repeaters in consecutive slots with the prescribed odd/even bus assignment. On SNT10D at 60 to 70 C, observe the two-slot clearance beside the power supply and between repeater sets. SENG and SCS R1.02 are the minimum listed revisions.

          Features:

          • Current consumption: 0.5 A
          • Connection topologies: Star and chain
          • ProSafe-RS optical ESB
          Use SNT401-13 S1 only within the documented ProSafe-RS optical ESB arrangement and applicable installation instructions.
          INTERCHANGEABILITY

          Replace SNT401-13 S1 within ProSafe-RS optical ESB

          Record the complete SNT401-13 S1 label and the slave endpoint before removal. A master must remain a master, and the optical pairing table must match the installed final suffix; selecting an SNT501 solely because its enclosure looks similar reverses the link role.
          Retain the bus 1 and bus 2 slot positions and identify whether the electrical ESB connector unit includes a terminator. The /CU1N and /CU1T arrangements are different accessories. The absence of an option on the order line must not be interpreted as either accessory being supplied.
          After replacement, confirm both ESB paths and the actual remote-node status in the approved maintenance procedure. Review the installed SENG/SCS revision, total optical length and high-temperature clearances before accepting the restored redundant arrangement.

          Features:

          • SNT401-13 S1 complete suffix
          • Matched optical slave: SNT501 with final suffix 3
          • Master/slave role and installed optical paths retained
          Use SNT401-13 S1 only within the documented ProSafe-RS optical ESB arrangement and applicable installation instructions.

          FREQUENTLY ASKED QUESTIONS

          Questions buyers ask about SNT401-13 S1

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

          • Does SNT401-13 S1 connect to SEC401 directly?

            SNT401-13 S1 accepts the electrical ESB connection from SEC401 or SEC402 on the safety control unit, or SSB401 on an applicable safety node.

          • Which slave suffix matches SNT401-13 S1?

            The selection table pairs the final 3 version of SNT401-13 S1 with an SNT501 final 3 version; the F pairing is a separate arrangement.

          • Can SNT401-13 S1 span 10 km in any installation?

            No. The SNT401-13 S1 family specification allows 10 km total across two stages only for the stated Vnet/IP R1.03-or-later configuration; the general two-stage limit is 5 km.

          • Where does bus 1 belong when duplicating SNT401-13 S1?

            For a duplex SNT401-13 S1 pair, bus 1 occupies the odd-numbered slot and bus 2 the next even-numbered slot.

          • What is the minimum software revision for SNT401-13 S1?

            The SNT401/SNT501 general specification lists SENG R1.02 and SCS R1.02 as the minimum revisions applicable to SNT401-13 S1.

          • Does SNT401-13 S1 include the ESB terminator?

            The complete option is decisive: /CU1N identifies the connector unit without a terminator, while /CU1T includes the terminator. The bare SNT401-13 S1 designation does not confirm either supplied option.

          • What should a distributor specify when quoting SNT401-13 S1?

            Quote SNT401-13 S1 in full, identify the required connector-unit option and state whether one module or a duplex pair is required. Availability and delivery belong on the written quotation.

          • Which receiving details distinguish a correct SNT401-13 S1 delivery?

            For SNT401-13 S1, compare the full label and style, master role, optical endpoint suffix and separately ordered connector unit against the accepted quotation; inspect the optical ports before installation.
