Product Description
Nabtesco BTC-304 Series Control PCB Card
NABCO Pneumatic Control System Interface | Marine & Industrial Automation | Base Model for BTC-304-01/51A Variants
1. Core Series Overview & Base Model Specs
The Nabtesco BTC-304 is the base model designation for a family of control PCB cards dedicated to NABCO pneumatic control systems—critical for marine vessels, offshore platforms, and heavy industrial plants. It serves as the hardware platform for variants like BTC-304-01 (standard I/O), BTC-304-51A (specialized marine variant), etc., acting as the central interface between NABCO controllers, pneumatic actuators/valves, and field sensors. The base design integrates an industrial 16-bit microcontroller with ECC memory, marine-grade conformal coating, IP20 protection, and redundant 24V DC power (15W max) to withstand salt spray, vibration, dust, and extreme temperatures (-25°C~+70°C). It features a modular I/O architecture (8 analog inputs, 4 analog outputs, 8 digital I/O) with 4-20mA/0-10V compatibility, ensuring precise pressure/flow/motion control and real-time fault monitoring.
• Core Role: NABCO pneumatic system interface; base platform for BTC-304-x variants; sensor data acquisition; valve positioner control; marine/industrial fault monitoring • Model Nomenclature: BTC-304 (base PN); BTC-304-01 (standard I/O); BTC-304-51A (marine-specialized variant with enhanced EMC/coating) • Base Specs: 8 AI (4-20mA/0-10V, 16-bit); 4 AO (4-20mA,<10ms response); 8 DIO (24V DC, 2A per channel); 24V DC redundant power; 15W max; -25°C~+70°C • Reliability: Conformal coating; IP20; reverse polarity/overcurrent/overtemp protection; ECC memory; hot-swap capable for 24/7 marine operations
2. BTC-304 Series Key Variants
| Model | Target Application | Key I/O & Features | Certifications/Coating |
|---|---|---|---|
| BTC-304 (Base) | General marine/industrial; platform for customization | 8AI/4AO/8DIO; Modbus RTU (RS-485); basic conformal coating | IEC 61010-1; IEC 61000-4 EMC; RoHS |
| BTC-304-01 | Standard NABCO pneumatic control; shipboard machinery rooms | Same I/O; front-panel status LEDs; fault relay (NO/NC); hot-swap | Marine DNV/GL; UL/CE; enhanced conformal coating |
| BTC-304-51A | Offshore platforms; harsh salt-spray environments; high-vibration vessels | Same I/O; reinforced EMC filtering; heavy-duty conformal coating; extended temperature range | DNV, ABS, Class I Div 2 (hazardous offshore); ATEX Zone 2 |
3. I/O, Communication & NABCO Integration
All BTC-304 series cards use the same NABCO backplane interface for plug-and-play integration into NABCO pneumatic control cabinets, eliminating custom wiring for base functions. Communication is via RS-485 Modbus RTU to connect with NABCO PLCs, HMIs, and central marine automation systems (e.g., IAS, alarm monitoring). The analog inputs capture precise pressure/flow/temperature data from marine sensors (4-20mA/0-10V, ±0.05% accuracy), while analog outputs drive NABCO pneumatic positioners for valve/actuator control—with fault-safe 0mA output on module failure. Digital I/O handles valve feedback, system interlocks, and local alarms, with isolated channels to prevent cross-talk in high-noise marine environments. Front-panel LEDs indicate power (green), communication (amber), and fault (red), paired with a global fault relay for remote alerting.
• Communication: RS-485 Modbus RTU; NABCO PLC/HMI integration; real-time data exchange; fault relay (NO/NC, 2A/24V DC) • Mounting: NABCO standard backplane; cabinet installation; IP20; conformal coating to resist salt/dust/vibration • Configuration: DIP switches for address/baud rate; NABCO configuration software for I/O mapping/fault-safe settings • Hot-Swap: Supported on compatible NABCO racks; allows replacement without cabinet power-down for critical marine systems
4. Safety, Compliance & Target Industries
The BTC-304 series complies with major marine and industrial standards, including IEC 61010-1 (electrical safety), IEC 61000-4 (EMC immunity), DNV, GL, ABS marine class certifications, RoHS, and for offshore variants (51A), Class I Div 2/ATEX Zone 2 for hazardous areas. The marine-grade conformal coating, sealed connectors, and robust power protection make the cards ideal for shipboard systems (thrusters, cargo loading, ballast, main engine controls), offshore oil & gas platforms, and industrial plants with pneumatic process control. The modular design ensures compatibility across different NABCO generations, reducing spares inventory for marine fleets.
• Certifications: CE, UL, DNV, GL, ABS; IEC 61010-1, IEC 61000-4; RoHS; ATEX Zone 2/Class I Div 2 (for offshore variants)
• Environment: -25°C~+70°C; 5-95% non-condensing humidity; salt-spray tested (marine variants); vibration/shock compliant with IEC 60068
• Applications: Marine vessel automation (thrusters, ballast, cargo); offshore platforms; industrial pneumatic control; NABCO system retrofits/upgrades
• Warranty: 12 months from Nabtesco (genuine modules); extended warranty available for marine fleets
5. Installation, Maintenance & Genuine Sourcing
Installation: Verify backplane compatibility; connect redundant 24V DC power (polarity check!); wire RS-485 and I/O; set DIP address/baud; check LED status before commissioning.
Maintenance: 6-month visual inspection for coating damage; 12-month communication/relay function test; hot-swap replacement if fault LED stays lit; use only Nabtesco genuine spare parts to avoid voiding marine certifications.
Configuration: Use NABCO-approved software to set I/O ranges, fault-safe output values, and Modbus parameters; back up configuration files for quick replacement.
Sourcing Note: BTC-304 is a base model—always specify the full part number (e.g., BTC-304-01, BTC-304-51A) when ordering to avoid receiving an incompatible variant for your NABCO system.
