| System Compatibility | Foxboro Evo Process Automation System, Standard 200 Series Subsystem |
⚙️ Functional Specifications
| Feature | Specification |
|---|---|
| Role | Facilitates redundant operation by connecting two FBM237 modules to a single TA, ensuring continuous output during module failure or replacement |
| Output Channels Supported | Eight 0-20 mA dc analog output channels (per FBM237 pair) |
| Redundancy Mechanism | Diode OR’d transmitter power from each FBM237 module to ensure redundant power supply to field devices; faulty module outputs driven to 0 mA, allowing the healthy module to maintain output |
| Connector Type | Interfaces with two adjacent baseplate termination cable connectors (odd/even positions: 1-2, 3-4, 5-6, or 7-8) and outputs to a single 25-pin male D-subminiature termination cable |
| Compatible TAs | P0916QC (PVC, compression), P0916YE (PA, compression), P0916QC (PVC, ring lug), P0917QZ (PVC, compression with bypass jacks) |
| Compatible Cables | Type 1 cables: P/PVC (P0916DA, P0916DB, P0931RM, P0916DC, P0916DD, P0916DE, P0916DF, P0916DG, P0916DH, P0916DJ for 0.5 to 30 m); LSZH (P0928AA, P0928AB, P0928AC, P0928AD, P0928AE, P0928AF, P0928AG, P0928AH, P0928AJ, P0928AK for 0.5 to 30 m); H/XLPE (P0916VA to P0916VJ, 0.5 to 30 m, no longer available) |
| Signal Integrity | Maintains galvanic isolation between channels (except between redundant pair outputs, which share a common field I/O connector) and supports HART protocol compatibility |
| Fail-Safe Operation | Supports AOUTR function block for redundant output writes; configurable fail-safe options (Hold/Fallback, 0 mA fallback per channel, Fieldbus Fail-Safe Enable, and Delay Time) |
| Certification Type | Inherits TA certifications: Type 1 (UL/UL-C Class I, Div 2, Groups A-D, T4; DEMKO Ex nA IIC T4 for Zone 2), Type 2 (non-incendive field circuits), Type 4 (Class 2 limited energy for P0917QZ), Type 5 (non-hazardous for P0917QZ) |
🔌 Physical Specifications
| Feature | Specification |
|---|---|
| Material | Not explicitly specified (likely polyamide or similar, based on TA materials) |
| Weight | Not specified (typically lightweight, <100 g, as a passive adapter) |
| Dimensions | Not specified (designed to fit adjacent baseplate connectors; compact to align with 45 mm FBM237 width) |
| Mounting | Attaches to two adjacent termination cable connectors on the modular baseplate (positions 1-2, 3-4, 5-6, or 7-8) |
| Cable Connection | 25-pin male D-subminiature for connection to TA via Type 1 termination cable |
