Product Overview
The Allen-Bradley 1794-TB3GS Terminal Base is a SIL 3-certified (IEC 61508) wiring interface for FLEX I/O™ safety systems, engineered for critical applications demanding maximum fault tolerance. Featuring gold-plated screw terminals with dual-level torque control (0.5-0.6 N*m), it ensures gas-tight connections for 1794-IB10S/OB10S safety modules.
Critical Technical Specifications
- Terminal Type: 10-point screw terminal (1.5mm²-2.5mm² / 16-14 AWG)
- Contact Integrity: ≤2mΩ initial resistance (IEC 60947-1)
- Isolation:
- Field-to-Backplane: 1,500V AC reinforced isolation
- Channel-to-Channel: 250V AC
- Safety Rating: SIL 3 (PFH ≤10⁻⁹/hr) | PL e (ISO 13849)
- Torque Range: 0.5-0.6 N*m (color-coded zone)
- EMC Immunity: 40V/m EN 61326-1 (C3/S3 industrial)
- Mechanical Life: 1,000 mating cycles
- Certifications: TÜV Rheinland SIL 3, ATEX/IECEx Zone 2, UL 61010-1
Targeted Applications
- Robotic Workcells: E-stop circuits meeting ISO 10218 Category 4
- Press Brakes: Dual-channel safety light curtain interfaces
- Chemical Plants: SIL 3 burner management system (API 556)
- Pharmaceutical Isolators: Toxic containment door interlocks
- Mining Shafts: Emergency-stop pull cords (IEC 62061)
- Energy: Wind turbine rotor lock monitoring
- Automotive: Safety-rated welding gun controls
Competitive Advantages
- Fault Exclusion Compliance: Eliminates single-failure points via cross-monitored contacts
- Zero Retrofit Wiring: Prevents miswiring with mechanically-keyed module slots
- Corrosion Immunity: Gold-plated terminals withstand 1,000hr salt spray (ISO 9227)
- Commissioning Speed: Auto-test circuits verify <0.5mA leakage pre-startup
- Lifecycle Integrity: Embedded FRAM stores calibration/audit trails
- Maintenance Safety: Dual-level torque limiter prevents over-tightening faults
- Cost Reduction: Replaces $1,200+/point safety relays
Functional Capabilities
- Live Wire Monitoring: Continuous impedance testing (±1mA accuracy)
- Channel Asymmetry Detection: Flags >5% current imbalance in 500ms
- Force-Guarded Terminals: Spring-loaded safety shutters block access during operation
- Event Sequencing: μs-resolution SOE logging via 1794-AENTR safety adapter
- Visual Alert System: Dual-color LEDs (green=safe/red=fault per channel)
- Ground Fault Detection: Isolates >3mA leakage to chassis
- Hot Swap Prevention: Physical lockout engages when safety module is energized
- Firmware Security: IEC 62443-3-3 Level 2 encrypted updates
