Product Description
Product Parameters for P0924DT (Redundant Adapter for FBM216b)
📘 Product Overview
| Field | Details |
|---|---|
| Manufacturer | Foxboro (by Schneider Electric) |
| Part Number | P0924DT (superseded by RH924DT) |
| Product Type | Redundant Adapter |
| Function | Connects a pair of FBM216b modules to a single termination assembly (TA) for redundant operation, combining field inputs and power supplies |
| System Compatibility | Used with FBM216b Redundant HART Communication Input Module in Foxboro Evo Standard 200 Series Subsystem |
| Associated PSS Document | PSS 31H-2S216 |
⚙️ Functional Specifications
| Feature | Specification |
|---|---|
| Purpose | Facilitates redundancy by connecting two FBM216b modules (Master and Tracker) to a single TA, ensuring continuous operation if one module fails |
| Input Signal Handling | Combines eight individually isolated 4 to 20 mA analog inputs (with or without HART FSK signals) from both FBM216b modules to a single TA |
| Power Supply Handling | Diode OR’d per-channel power supplies from both FBM216b modules to provide redundant power to the field device loops via the TA |
| Input Resistance Impact | Adds to total input resistance: - Externally Powered: 282 Ω (including TA and adapter) - Internally Powered: 302 Ω (including TA and adapter) |
| Loop Resistance | Provides sufficient loop resistance to support HART Hand-Held Terminal or PC20 Intelligent Field Device Configurator (PSS 2A-1Z3 E) |
| Compatibility | Designed for use with FBM216b and TA part number RH924JH (supersedes P0924JH) |
📏 Physical Specifications
| Feature | Specification |
|---|---|
| Mounting | Attaches to two adjacent baseplate termination cable connectors (positions 1-2, 3-4, 5-6, or 7-8) to provide a single termination cable connection to the TA |
| Termination Cable Connection | Connects to a single Type 1 termination cable (37-pin D-subminiature at baseplate end, 25-pin D-subminiature at TA end) |
| Weight | Not explicitly specified (assumed to be minimal, similar to other redundant adapters in the series, e.g., ~100-200 g based on related components) |
| Material | Not explicitly specified (assumed to be rugged, compatible with Class G3 harsh environments, likely aluminum or similar based on FBM216b design) |
✅ Regulatory Compliance
| Certification Type | Details |
|---|---|
| Contextual Compliance | Inherits compliance from FBM216b and TA: - UL/UL-C listed for Class I, Groups A-D, Division 2, T4 hazardous locations - DEMKO certified Ex nA IIC T4 for Zone 2 per ATEX Directives 94/9/EC (pre-Apr 20, 2016) and 2014/34/EU (post-Apr 20, 2016) - Complies with EMC Directive 2004/108/EC (pre-Apr 20, 2016) and 2014/30/EU (post-Apr 20, 2016) per EN61326-1:2013 Class A - Complies with RoHS Directive 2011/65/EU - ABS Type Approved and Bureau Veritas Marine Certified for Environmental Category EC31 |
| Conditions of Use | Must be installed per Standard and Compact 200 Series Subsystem User’s Guide (B0400FA) |
🔧 Additional Features
| Feature | Details |
|---|---|
| Superseded Part | P0924DT is superseded by RH924DT |
| Redundancy Support | Ensures high availability by allowing either FBM216b module to be replaced without disrupting field inputs or power; inputs are maintained by the redundant module |
| System Integration | Works with FBM216b’s redundant 2 Mbps Fieldbus communication (Path A or B) and TA (RH924JH) to connect field devices |
| Cable Compatibility | Supports Type 1 termination cables (P/PVC or LSZH, lengths up to 30 m) as listed in Table 2 of PSS 31H-2S216 |
