        Overview Manuals Applications Communication Environment Safety

        Features:

        • Coordinates as many as sixteen CHARMs Smart Logic Solvers on one SZ Controller.
        • Provides redundant Ethernet paths to the LSN and to the ACN or Modbus TCP ports.
        • Supports simplex or redundant installation on vertical or horizontal safety carriers.
        The current ordering configuration is KL2001X1-BB1, the DeltaV SIS SZ Controller.

        It coordinates safety-network communication, exchanges secure data with assigned CSLSs, and connects the safety architecture to the DeltaV control network.

        Before replacement, verify carrier orientation, Ethernet isolation ports, redundancy, LSN and ACN addressing, Modbus settings, internal-fuse status, and system revision.

        Availability is subject to Apter Power inventory and sourcing confirmation.

        • Coordinates distributed safety logic in emergency shutdown, fire and gas, and process-protection systems.
        • Connects CHARMs Smart Logic Solvers across the Local Safety Network while integrating with the Area Control Network.
        • Supports remote I/O node reporting for engineered DeltaV SIS architectures that require secure data exchange.
        • Uses redundant Ethernet connections through the safety carrier to the LSN and the ACN or Modbus TCP ports.
        • Assigns LSN and ACN addresses during commissioning, while Modbus TCP addressing is manual and slave-only.
        • Supports full-duplex 10/100BASE-TX copper links with RJ45 connections and a documented 100 m distance.
        • Operates across a documented ambient temperature range from −40 to +70°C.
        • Supports 5 to 95% relative humidity in a non-condensing environment.
        • Uses conformal coating for ISA-S71.04-1985 Class G3 airborne-contaminant conditions.
        • Maintains a dedicated Local Safety Network path between the SZ Controller and assigned CSLS units.
        • Contains an internal non-replaceable fuse, requiring an approved replacement procedure after a fuse-related failure.
        • Requires topology, redundant-port, addressing, and power isolation checks before controller exchange.

        Description
        KL2001X1-BB1 is the Emerson DeltaV SIS SZ Controller used to coordinate CHARMs Smart Logic Solvers and safety-network communication.

        The controller provides redundant 10/100BASE-TX Ethernet connections through the safety carrier to the Local Safety Network and Area Control Network or Modbus TCP ports, with automatic LSN and ACN addressing during commissioning.

        A simplex or redundant replacement must preserve carrier orientation, Ethernet isolation ports, addressing, security architecture, and supported system configuration. The internal fuse is not replaceable, so isolate power before hardware exchange.

        Technical notes
        KL2001X1-BB1 replacement requires LSN/ACN addressing and redundancy-topology verification; its internal fuse is non-replaceable, so isolate power before hardware exchange.

        FAQS

        The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
        VIEW ALL FAQS
        Can KL2001X1-BB1 be installed as either simplex or redundant?
        Yes. The supported carrier accepts one simplex or two redundant SZ Controllers, but the physical and configured topology must match.
        What network architecture must be preserved when replacing KL2001X1-BB1?
        Preserve the LSN connection to the CSLSs and the ACN or Modbus TCP path through the approved safety carrier and isolation ports.
        Does KL2001X1-BB1 require manual addressing on every network?
        LSN and ACN addresses are assigned during commissioning; Modbus TCP addressing is manual and operates in slave mode.
        Can the internal fuse in KL2001X1-BB1 be replaced in the field?
        No. Emerson identifies the internal fuse as non-replaceable, so a fuse-related failure requires an approved controller replacement procedure.
        What should be reviewed before changing the KL2001X1-BB1 carrier orientation?
        Confirm cabinet layout, DIN-rail orientation, Ethernet isolation ports, redundant arrangement, wiring, and project documentation.
        How should buyers request KL2001X1-BB1 documentation and availability?
        Provide the complete BB1 model, system version, carrier arrangement, quantity, destination, and required approvals.
