Product Overview
The Allen-Bradley 1794-TB3T Terminal Base Unit is a rugged interface module for Rockwell Automation's FLEX I/O™ system, designed to streamline wiring and enhance reliability in industrial environments. Featuring patented push-lock spring terminals, this DIN-rail-mountable base eliminates screw tightening and enables tool-less wiring (0.5-2.5mm² / 20-14 AWG). Its high-impact polyamide housing achieves IP66/IP68 protection against dust, high-pressure washdowns, and submersion, while operating across -25°C to +70°C.
Critical Technical Specifications
- Terminal Type: 16-point spring-clamp (push-lock mechanism)
- Contact Resistance: ≤5mΩ per terminal
- Wiring Range: 0.5-2.5mm² solid/stranded (copper only)
- Mating Cycles: 100+ insertions/extractions without degradation
- Isolation Voltage: 250V AC terminal-to-rail
- Environmental: IP68 for temporary submersion (1m/30 min) | NEMMT 6/6P
- EMC Immunity: EN 61326-1 (30V/m RF)
- Certifications: UL 61010-1, ATEX II 3G, IECEx, RoHS III
Targeted Applications
- Packaging Lines: High-speed filling machine sensor connections
- Automotive Paint Shops: Tool-less repairs in corrosive overspray environments
- Water Treatment: Valve island terminals in flood-prone pump stations
- Food Processing: Washdown-compatible sauce dosing system wiring
- Mining: Dust-proof conveyor junction boxes
- HVAC: Vibration-resistant damper control cabinets
- Chemical Dosing: Acid-resistant terminals for pH adjustment systems
Competitive Advantages
- Time Savings: 30-second rewiring vs. 10+ minutes for screw terminals
- Vibration Immunity: Spring clamps maintain >45N retention at 5g vibration
- Error Proofing: Guaranteed insertion force (6N) prevents loose wires
- Longevity: 10M+ mechanical cycles (5× screw terminal lifespan)
- Space Efficiency: 42mm width accommodates 16 I/O points
- Safety Compliance: V0 flammability rating (UL 94)
- Corrosion Defense: Salt-spray resistant (ISO 9227 C5M)
Functional Capabilities
- Dual-Use Terminals: Accepts ferrules or bare wire with automatic clamping
- Grounding Integrity: Dedicated PE terminal (10mm² capacity)
- Visual Verification: Transparent cover for contact inspection
- Module Locking: Tool-less quarter-turn lock secures I/O modules
- Field Marking: Laser-engravable label slots
- Hot-Swap Readiness: Replace modules without rewiring
- ESD Protection: 8kV contact discharge (IEC 61000-4-2)
- Retrofit Flexibility: Compatible with legacy 1794-TB3 bases
