The Allen-Bradley 1492-H4 is a PCB/panel-mount terminal block designed for secure, high-density wiring in industrial control systems. Part of Rockwell Automation's 1492 Series, it features polyamide insulation with UL 94V-0 flame resistance and nickel-plated copper alloy contacts for low-resistance connections. This screw-clamp terminal accepts 12-24 AWG wires and supports voltages up to 600V AC/DC, making it ideal for PLC I/O, motor control centers (MCCs), and power distribution panels. Its compact design (5.08 mm pitch) enables space-efficient DIN rail mounting, while color-coded markers and test points simplify installation and diagnostics in high-vibration environments.
- Voltage Rating: 600V AC/DC (UL 508/CSA C22.2).
- Current Rating: 16A continuous (at 60°C).
- Wire Range: 12-24 AWG (3.3-0.2 mm²).
- Contact Resistance: <3 mΩ initial.
- Insulation Material: Polyamide (PA66), UL 94V-0 rated.
- Clamp Type: Screw-operated cage clamp (torque: 0.5-0.6 Nm).
- Operating Temp: -40°C to +105°C (-40°F to +221°F).
- Mounting: DIN rail TS35 (EN 60715).
- Safety Certs: UL, CSA, CE, RoHS.
- Dielectric Strength: 4kV AC (1 min).
The 1492-H4 is integral to industrial automation wiring infrastructures:
- PLC Systems: Terminating ControlLogix®/CompactLogix™ I/O modules.
- Motor Starters: Wiring overload relays and contactors in MCC buckets.
- Power Supplies: Distributing 24VDC to sensors and valves.
- Control Panels: Organizing field device wiring (e.g., push buttons, lights).
- HVAC Systems: Routing control signals for dampers and compressors.
Its vibration resistance (IEC 60068-2-6: 5-500 Hz) suits mobile equipment and high-shock environments.
- Space Optimization: 5.08mm pitch saves 30% panel space vs. standard blocks.
- Error-Proof Wiring: Color zones and numbered markers prevent miswiring.
- Enhanced Safety: Double insulation and arc shields meet UL 508A enclosure rules.
- Labor Efficiency: Front access/rear test points reduce troubleshooting time.
- System Integration: Plug-and-play with Allen-Bradley 1492-SPM adapters for point I/O.
- Secure Clamping: Cage clamps grip stranded/stranded wires without solder sleeves.
- Test & Isolation: Disconnect switches and test ports allow live circuit verification.
- Modular Stacking: Horizontally or vertically bridgable for multi-phase systems.
- EMI Shielding: Metal partitions isolate signal/power lines; optional shields available (1492-W4).
- Durability: Salt spray resistance (IEC 60068-2-52: 48h) for marine/oilfield use.
