1.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. Its reinforced polyamide housing achieves ​IP67/NEMA 6​ protection against harsh washdowns, oils, and chemicals (–40°C to +70°C). The dual-channel topology provides ​1,500V AC galvanic isolation​ between field wiring and backplane, while ​tamper-proof covers​ prevent unauthorized access in safety-certified installations. Integrated diagnostic circuits detect wire breaks during commissioning via Studio 5000® LogixGuard™.


​2.Critical Technical Specifications

Safety-essential parameters:

  • 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

​3.Targeted Applications

Functional safety-critical systems:

  • 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

4.​Competitive Advantages

Safety engineering innovations:

  • 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

​5.Functional Capabilities

Advanced safety diagnostics:

  • 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
