Bachmann BS210 Backplane Module
1. Product Description
A high-capacity industrial backplane module designed for medium-to-large automation systems, serving as a centralized interconnection and power distribution hub for Bachmann modules. The Bachmann BS210 enables stable power delivery and real-time high-speed signal transmission between controllers (e.g., MPC240), I/O modules (e.g., DI016-C, DIO32-C), communication modules (e.g., FS212/N), and specialty modules (e.g., SEM201). With 10 standard slots, dual redundant power inputs, and enhanced anti-interference performance, it is ideal for harsh industrial environments requiring scalable, reliable system integration (e.g., large production lines, complex process control networks).
2. Detailed Specifications
2.1 Slot Configuration
- Number of Slots: 10 standard slots (compatible with Bachmann 32-bit industrial modules)
- Slot Compatibility: Supports processor modules, digital/analog I/O modules, communication modules, motion control modules (e.g., SEM201), and temperature input modules (e.g., PATI216)
- Slot Spacing: 15 mm per slot (compliant with EN 50022 DIN rail standard)
- Slot Isolation: 3 kV DC isolation between adjacent slots (reduces cross-signal interference; higher than entry-level backplanes)
2.2 Power Distribution
- Input Voltage: 24 V DC ±20% (dual redundant power inputs; automatic failover if one input fails)
- Power Output to Modules: 24 V DC (stable output per slot; 1 A maximum current per slot)
- Power Consumption: Typical 3 W (excluding power consumed by connected modules), Maximum 5 W
- Centralized: Overvoltage, undervoltage, short-circuit, and reverse polarity protection
- Per-slot: Current limiting (prevents single-module overload from affecting the entire backplane)
2.3 Signal Transmission
- Signal Bus Type: High-speed parallel data bus + optional Ethernet backplane bus (dual-bus design for redundancy)
- Maximum Signal Transmission Rate: Up to 200 Mbps (parallel bus); 1 Gbps (Ethernet bus, if enabled)
- Signal Isolation: 3 kV AC isolation between signal lines and power lines (enhances anti-interference in noisy industrial sites)
- Bus Protocol Support: Bachmann proprietary communication protocol; compatible with Modbus TCP/RTU, Profinet IO, and Ethernet/IP (via connected modules)
2.4 Operating Environment
- Operating Temperature: -40°C ~ +70°C
- Storage Temperature: -40°C ~ +85°C
- Relative Humidity: 5% ~ 95% (non-condensing)
- Vibration Resistance: 10-500 Hz, 2 g acceleration (compliant with IEC 60068-2-6)
- Shock Resistance: 30 g acceleration, 11 ms duration (compliant with IEC 60068-2-27)
- EMC Compliance: EN 61000-6-2 (industrial immunity), EN 61000-6-4 (industrial emissions)
2.5 Physical Dimensions
- Size: 280×80×30 mm (Length×Width×Height)
- Mounting Type: DIN rail mounting (compatible with EN 50022 standard)
- Weight: Approximately 350 g
- Material: Flame-retardant ABS plastic (UL94 V-0 rating; reinforced housing for impact resistance)
2.6 Mechanical & Electrical Features
- Module Locking: Metal snap-lock mechanisms (more durable than plastic; prevents module loosening due to long-term vibration)
- Connection Type: Gold-plated pin connectors (low contact resistance; minimum 15,000 insertion/extraction cycles for long service life)
- 2 power indicators (green: normal; red: fault) for dual redundant inputs
- 10 slot status indicators (green: module connected; red: module fault)
- 1 bus status indicator (yellow: active; red: bus error)
3. Advantages & Features
- High Slot Capacity: 10 slots support large-scale system configurations (e.g., 1 controller + 6 I/O modules + 2 communication modules + 1 specialty module), reducing the need for multiple backplanes.
- Redundant Power Input: Dual 24 V DC inputs with automatic failover enhance system reliability—avoids downtime from single power supply failure (critical for 24/7 production lines).
- Dual-Bus Redundancy: Parallel + Ethernet bus design ensures uninterrupted signal transmission; Ethernet bus enables high-bandwidth data exchange for complex systems (e.g., multi-axis motion control).
- Enhanced Isolation: 3 kV slot and signal isolation reduces electromagnetic interference (EMI) from nearby motors, inverters, or high-voltage equipment.
- Intuitive Status Monitoring: Multi-color LEDs for power, slots, and bus simplify fault diagnosis—technicians can quickly identify issues (e.g., faulty module, power failure) without additional tools.
4. Application Fields
- Large-Scale Industrial Automation: Automotive assembly lines, electronics manufacturing plants (connecting distributed I/O modules, robots, and central controllers).
- Complex Process Control: Chemical refineries, oil & gas processing plants (integrating analog I/O, temperature modules, and safety controllers for centralized process management).
- Smart Factory Integration: IoT-enabled manufacturing facilities (connecting edge computing modules, data loggers, and MES systems via Ethernet bus for real-time data flow).
- Power Distribution Automation: Smart grid substations, large-scale solar/wind farms (integrating power monitoring modules, communication modules, and controllers for grid stability).
- Transportation Infrastructure: Railway signaling systems, automated port container handling (reliable module interconnection for safety-critical control).
5. Precautions
- Mount on EN 50022-compliant DIN rails; ensure 70 mm clearance on both sides for heat dissipation (prevents overheating of connected modules).
- Avoid installation in areas with direct sunlight, oil splashes, or corrosive gas (e.g., chemical plant exhaust).
- Power off the backplane before installing/removing modules; align module connectors with slot guides (do not force insertion—prevents bent pins).
- Use the metal snap-lock to secure modules (verify locks are fully engaged to avoid vibration-induced disconnection).
- Connect dual power inputs to separate 24 V DC power supplies (e.g., primary and backup) for true redundancy.
- Use power cables with 1.5-2.5 mm² cross-section; tighten terminal screws to 0.6-0.8 N·m torque (prevents loose connections and voltage drops).
- Keep backplane power cables separate from high-voltage cables (e.g., 380 V motor cables) and signal cables (e.g., sensor wires) to reduce EMI.
- Use shielded cables for external communication lines; ground shields at the backplane end.
- Inspect connectors quarterly (clean dust with a dry, soft brush—do not use liquids).
- Check LED indicators monthly to identify latent issues (e.g., intermittent bus errors).
- Do not disassemble the backplane (disassembly voids the warranty and risks damaging internal isolation components).
