Contact Block Construction

The Allen-Bradley 80026-044-06-R contact block features a rugged thermoplastic housing designed to withstand the rigors of industrial environments. The contact mechanism consists of silver alloy contacts mounted on a precision mechanism that ensures positive opening and closing action.

The contact block is designed for easy mounting to 800T Series enclosures using a standard mounting mechanism. Multiple contact blocks can be stacked to provide complex control functions within a single operator station.

Terminal connections are made via screw terminals, which provide a secure connection and allow for easy installation and maintenance. The terminals are typically rated for 14-22 AWG wire.

Operating Principles

The 80026-044-06-R is a normally closed (NC) contact block, meaning the contacts are closed in the normal (unactuated) state. When the associated operator (push button, selector switch, etc.) is actuated, the contacts open, interrupting the circuit.

The contact block utilizes a mechanical linkage that transfers the motion from the operator head to the contact mechanism. This linkage is designed to provide positive actuation and ensure reliable contact operation throughout the life of the product.

The contact block is designed with a "snap-action" mechanism that ensures quick make-and-break operation, minimizing arcing and extending contact life.

Installation Guidelines

When installing the 80026-044-06-R contact block, follow these guidelines:

• Ensure the power is disconnected before installing or servicing the contact block
• Mount the contact block to the 800T Series enclosure according to the manufacturer's instructions
• Connect wires to the appropriate terminals, ensuring proper torque (typically 0.5-0.7 N·m)
• Verify that the contact block is properly aligned with the operator head
• Test the operation of the contact block before applying power to the system
• Ensure that the enclosure cover is properly installed to maintain the ingress protection rating

Maintenance & Troubleshooting

Proper maintenance of the 80026-044-06-R contact block will ensure reliable operation and extend its service life:

• Periodically inspect the contact block for signs of damage or wear
• Check terminal connections to ensure they are tight and secure
• Clean the contact block using a dry, lint-free cloth; avoid using solvents or abrasive materials
• Test the contact operation using a multimeter to verify proper functioning
• Replace the contact block if contacts are pitted, burned, or show signs of excessive wear
• Ensure that the enclosure is properly sealed to prevent ingress of contaminants

Common issues with contact blocks include:

• Contact welding due to excessive current or arcing
• Contact wear due to frequent operation
• Contamination causing poor contact operation
• Loose terminal connections causing overheating
