Core Functions & Compatible ModulesThe P0973CN expansion backplane features a 4-slot modular design. It primarily supports a redundant pair of FCP270 Field Control Processors (occupying two slots), while the remaining two slots can accommodate a redundant pair of FEM100 Fieldbus Expansion Modules.
This configuration is specifically engineered for systems requiring enhanced I/O distribution capability. With the expansion support of FEM100 modules, a single FCP270 Control Processor can be expanded to support up to four additional expansion fieldbuses. Each expansion fieldbus can further connect up to 32 Series 200 FBM Fieldbus Modules, significantly expanding the system’s I/O access capacity.
In addition, the backplane reserves installation space for optical fiber splitters/combiners for FCP270 modules, ensuring the stable operation of redundant FCP270 modules. It is also compatible with the redundant communication architecture of the Foxboro Evo™ system, thus guaranteeing the reliability of data transmission.
Notably, this backplane is equipped with no backplane identification DIP switches and requires no hardwired address configuration, simplifying the installation and commissioning processes.
Installation & Configuration FeaturesIn terms of mounting method, the P0973CN is a vertical DIN rail-mount backplane that must be installed on a non-isolated, mechanically supported vertical DIN rail. The rail can be positioned either inside or outside the equipment enclosure and secured firmly with fasteners.
It offers flexible mounting compatibility and can be used in combination with other Series 200 backplanes. When the system is equipped with a redundant bus, it supports in-service expansion without interrupting system operations, greatly improving operational and maintenance convenience.
The dimensions of this backplane comply with the standard specifications for Series 200 vertical-mount backplanes, and specific details can be referred to the dimension drawing (Figure 13) in the product documentation. Moreover, its weight without modules adheres to the lightweight design principle of Series 200 backplanes, facilitating on-site deployment.
In addition, the backplane is equipped with clearly labeled connectors, including power interfaces, module interfaces, and field I/O interfaces. The module slots are designed with guiding structures to ensure correct module insertion and reduce the risk of installation errors.
Technical SpecificationsPower Supply & CommunicationPower Supply Requirements: Supports redundant 24V DC primary and backup power inputs, compatible with FPS480-24, FPS400-24, FPS240-24 or FPS120-24 series power supplies.
Communication Bus: Interconnection between backplanes is realized via a 2 Mbps HDLC redundant serial bus (Module Fieldbus). A/B module fieldbuses are connected with shielded twisted-pair cables, effectively reducing the impact of electromagnetic interference on communication. The maximum allowable total length of bus cables is 60 meters (198 feet).
Environmental AdaptabilityOperating Temperature: -20°C to +60°C (-4°F to +140°F), meeting the temperature requirements of most industrial sites.
Relative Humidity: 5% to 95% (non-condensing), suitable for humid or dry industrial scenarios.
Altitude Range: -300 m to +3,000 m (-1,000 ft to +10,000 ft) under operating conditions; expandable to -300 m to +12,000 m (-1,000 ft to +40,000 ft) under storage conditions.
Pollution Degree: Complies with Pollution Degree 2 as defined in IEC 664-1, and is compatible with the G3 (severe) pollution environment specified in ISA S71.04. It ensures stable operation whether installed inside an enclosure or not.
Physical & Compliance CharacteristicsMaterial & Flame Retardant Rating: The main body is made of PC and ABS materials with a flame retardant rating of UL94 V0, ensuring safe operation in industrial environments.
Compliance Certifications: Complies with the EU EMC Directive 2014/30/EU, Low Voltage Directive 2014/35/EU and ATEX Directive 2014/34/EU; certified by UL/UL-C for use in Class I, Divisions A-D, Zone 2, T4 temperature class explosive atmospheres; compatible with EC31 environmental category for marine certification (note that this model does not include marine certification itself); complies with the EU RoHS Directive 2011/65/EU for environmental compliance.
Application Scenarios & Advantages
The P0973CN expansion backplane is primarily applied to I/O expansion scenarios of the Foxboro Evo process automation system. It is particularly suitable for industrial sectors that require enhancing system I/O capacity based on FCP270 Control Processors, such as petrochemicals, power generation, water treatment, and manufacturing.
Its core advantages are as follows:
High Scalability
Redundant configuration of FEM100 modules enables stepped improvement of I/O capability, satisfying the future upgrade requirements of the system.
Strong Compatibility
It achieves seamless compatibility with other Series 200 modules (e.g., FCP270, FBM, etc.) and existing I/O subsystems, allowing system integration without the need for additional interface hardware.
High Reliability
The passive backplane design reduces potential points of failure. Supported by redundant power supplies and communication buses, coupled with its robust environmental adaptability design, it ensures continuous and stable operation in industrial field environments.
Flexible Installation
The vertical DIN rail mounting method saves space and supports online expansion, which reduces the costs associated with system downtime for maintenance.
