Honeywell CC-SCMB02 51199932-200 Replacement for C300

Product Overview

Honeywell CC-SCMB02 51199932-200 Replacement for C300: Seamless DCS Migration & Upgrade Solution

The Honeywell CC-SCMB02 (Part No. 51199932-200) is a critical DCS Module Assembly designed for the Experion PKS C300 Controller Series. As legacy Honeywell TDC 3000, TPS, and early Experion R100/R200 systems reach end-of-life, plant engineers and procurement teams are actively seeking verified replacement modules that deliver a smooth, low-risk migration path without requiring full system redesign or extended production shutdowns.

This module serves as a direct replacement or upgrade solution for aging C300 platform assemblies, including discontinued backplane interface boards and controller module assemblies previously used in conjunction with the CC-PCNT01 process controller node and CC-PAIH01 analog input modules. Whether your facility is retiring a TDC 3000 LCN node or consolidating redundant C300 cabinets, the CC-SCMB02 provides the hardware continuity needed to maintain system integrity during phased migration.

Seamless Upgrade Solutions

A successful migration to the CC-SCMB02 within an Experion PKS C300 environment typically involves coordinating several interdependent hardware components. During the retrofit process, engineers commonly work alongside the CC-PCNT01 C300 Process Controller Node, which serves as the primary controller paired with this module assembly. The CC-PAIH01 Analog Input IOTA and CC-PAOH01 Analog Output IOTA are frequently replaced in the same maintenance window, as their terminal wiring maps directly to the new C300 backplane layout.

For facilities migrating from TDC 3000 or TPS architectures, the CC-PDOB01 Digital Output Module and CC-PDIB01 Digital Input Module are standard additions to the bill of materials, ensuring I/O continuity across the new chassis. Communication integrity during the cutover is maintained through the CC-TCF901 FTE Switch Module, which supports the Fault Tolerant Ethernet backbone that the C300 platform relies on for controller-to-server communication.

In cabinet-constrained environments — particularly older process areas where DIN rail space is limited — the CC-PWRR01 Redundant Power Supply Module is often specified alongside the CC-SCMB02 to ensure uninterrupted 24 VDC supply during hot-swap operations. For sites requiring signal isolation between legacy field devices and the new C300 I/O modules, a Pepperl+Fuchs or MTL signal isolator/barrier is commonly integrated at the marshalling cabinet level.

Programming migration from Control Builder R100 to R400+ is typically performed using a Honeywell Experion PKS Engineering Station with the updated Control Builder software suite, and field verification is carried out using a CC-PROG01 programming cable and diagnostic tool to confirm module health and FTE link status prior to live commissioning.

Retrofit Guidance FAQ

Q: Is the CC-SCMB02 a direct drop-in replacement for older C300 module assemblies?
A: In most cases, yes. The CC-SCMB02 uses the standard C300 chassis slot interface and IOTA backplane connector. Physical installation is straightforward. However, if migrating from a pre-R300 Experion environment, a Control Builder software upgrade and FTE network reconfiguration are required before the module can be commissioned online.

Q: Do I need to rewire field terminals when replacing a legacy module with the CC-SCMB02?
A: Field wiring at the IOTA terminal level is preserved. The CC-SCMB02 connects to the existing IOTA backplane, so marshalling cabinet wiring and field cable terminations remain unchanged. Only the controller-side module is swapped.

Q: Is the FTE communication protocol fully compatible with my existing C300 network?
A: Yes. The CC-SCMB02 supports Honeywell’s Fault Tolerant Ethernet (FTE) protocol natively. It integrates directly with existing FTE switch infrastructure without requiring protocol converters or additional network hardware, provided the Experion server is running R400 or later.

Q: How much cabinet space does the CC-SCMB02 require?
A: The module occupies a single standard C300 chassis slot. No additional DIN rail space or external mounting is required. This makes it particularly suitable for retrofit projects in space-constrained control cabinets where minimizing physical footprint is a priority.

Q: Can this module be used in a redundant controller configuration?
A: Yes. The C300 platform supports redundant controller pairs. The CC-SCMB02 can be deployed in a primary/secondary redundant configuration using a matching redundancy module and FTE switch, providing bumpless switchover in the event of a controller fault.

Q: What programming changes are needed after installation?
A: If replacing a like-for-like C300 module assembly, the existing Control Builder database can be downloaded directly to the new module after hardware replacement. For cross-generation migrations (e.g., from HPM or APM), function block re-mapping and I/O address reassignment are required in Control Builder R400+.

Warranty Assurance

Every Honeywell CC-SCMB02 51199932-200 shipped by TOPNLMS is backed by a 12-month replacement warranty from the date of delivery. Prior to shipment, each unit undergoes a multi-point outgoing inspection covering visual integrity, connector condition, firmware version verification, and functional bench testing where applicable. Units are shipped in anti-static packaging with full traceability documentation.

In the event of a confirmed hardware defect within the warranty period, TOPNLMS provides a direct replacement unit dispatched within 3–5 business days, with no requirement to return the defective unit before the replacement is shipped in most cases. Our after-sales response team is reachable via email and phone to support installation queries, compatibility verification, and warranty claims throughout the 12-month coverage period.

For procurement teams managing critical spares programs, TOPNLMS maintains buffer stock of high-demand C300 platform modules to support emergency orders with expedited shipping from our Xiamen warehouse. Lead times, stock availability, and volume pricing are available upon request.
