          PRODUCT DESCRIPTION

          DSTC452 MasterFieldbus Coaxial Modem

          ABB identifies DSTC452, article 5751017-A, as a coaxial modem for MasterFieldbus. It is a communications component rather than a motor protection relay. The Advant Controller 450 product guide lists it separately from the DSTC454 and DSTC454L optical modems.

          Selection depends on the installed coaxial path and the specific MasterFieldbus arrangement. Check both the modem label and the actual cable medium before ordering. A configuration example can guide comparison, but it does not establish every DSTC452 unit’s mains rating or installed cable limits.

          Match DSTC452 to the coaxial MasterFieldbus link

          In ABB Advant Master, the DSTC452 (5751017-A) uses frequency-shift keying (FSK) to carry serial I/O bus signals over coaxial cable. Locate the MasterFieldbus segment on the site drawings and confirm that the installed modem position is specified for this coaxial article.
          ABB references two mating plugs: the 3-position 2664197-3 and the 10-position 2664193-10. Check both against the installed harness. The product sheet identifies the plugs, but the approved cabinet drawings are the source for their pin assignments and how they connect.
          Follow the documented cable path between the modem and the connected I/O stations. If the site has separate or redundant paths, identify the affected path before service and verify its cable and termination arrangement against the as-built drawings rather than assuming that each segment is wired alike.

          Features:

          • FSK for the serial I/O bus
          • Coaxial MasterFieldbus connection
          • ABB-listed 3- and 10-position plugs
          Connector fit alone does not establish compatibility. Confirm the bus medium and wiring against the approved drawings before installation.
          INTERCHANGEABILITY

          Verify the 5751017-A assembly before replacement

          Record both the DSTC 452 type designation and the complete 5751017-A product ID from the removed unit. Compare them with the offered assembly and the site parts list. A similar front panel or a shared product family is not enough to establish a replacement match.
          ABB lists EXC5751017-A as the exchange reference. If the quote uses that number, verify that it is an exchange offer and confirm the return terms and which connectors or other accessories are included. The ABB product details list references, not the contents of a particular shipment.
          For fuse service, match the ABB reference 3BSC770001R137 as well as the listed 200 mA rating. After approved service, use the site commissioning procedure to confirm that the affected remote I/O stations communicate on the intended bus segment before returning the installation to operation.

          Features:

          • Exact 5751017-A nameplate match
          • EXC5751017-A exchange identifier
          • 200 mA fuse, ABB 3BSC770001R137
          Do not substitute an optical DSTC454 or DSTC454L for the coaxial DSTC452 without an approved change to the network design.

          FREQUENTLY ASKED QUESTIONS

          Questions buyers ask about DSTC452

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

          • Can the ABB DSTC452 be used on Advant Fieldbus 100?

            ABB lists the DSTC452 under MasterFieldbus, not Advant Fieldbus 100. Check the bus name in the project documentation rather than selecting by cable type alone.

          • How long can the DSTC452 coaxial run be?

            ABB’s Advant Controller 450 guide shows a coaxial segment of up to 750 m in its example MasterFieldbus layout. Confirm the allowed length for your own cable and topology before extending the run.

          • Does one DSTC452 provide MasterFieldbus redundancy?

            A single modem does not create a redundant path. ABB describes physical redundancy using duplicated cable and modem paths. Verify how your existing installation implements that arrangement.

          • Where should I check first if several remote I/O units lose communication?

            Compare which units are affected with the MasterFieldbus drawings. If they share a segment, inspect that path and its documented termination before assuming several modems have failed.

          • Which fuse is listed for ABB part 5751017-A?

            ABB lists fuse 3BSC770001R137 at 200 mA for this article. Match the full fuse reference, not just its current rating.

          • Will a DSTC454 replace a DSTC452 on the existing coaxial cable?

            No direct substitution is documented. ABB lists DSTC454 for optical fiber and DSTC452 for coaxial cable. A change in cable medium requires an approved network design.

          • Is EXC5751017-A the same ordering reference as 5751017-A?

            ABB identifies 5751017-A as the product ID and EXC5751017-A as the exchange number. State which is being quoted and confirm any return conditions before placing the order.

          • Are the mating plugs included when I order a DSTC452?

            ABB references 3-position plug 2664197-3 and 10-position plug 2664193-10, but that listing does not establish package contents. Ask the seller to list included plugs separately on the quote.
