AutomationDirect ZL-RTB40 ZIPLink Feedthrough Connector Module

AutomationDirect ZL-RTB40 / ZL-RTB40-1 ZIPLink Feedthrough Connector Module Overview

The AutomationDirect ZL-RTB40 and ZL-RTB40-1 are 40-pole (or 48-pole for ZL-RTB40-1) feedthrough connector modules within the ZIPLink wiring solution. These modules provide a convenient and efficient way to connect pre-wired ZIPLink cables from PLC I/O modules to standard screw-type terminal block connections for field wiring. They help reduce wiring time, minimize wiring errors, and create a cleaner, more organized control panel.

Product Detailed Description

• Function: The ZL-RTB40 acts as an interface between the high-density connectors found on PLC I/O modules (via a ZIPLink cable) and individual field wires. It takes a bundled cable connection from a PLC and breaks it out into easily accessible screw terminals, allowing for simple connection of sensors, actuators, and other field devices.

• Purpose: It's specifically designed to:

• Reduce Wiring Time: Eliminates the need for individual wire termination at the PLC I/O module, greatly speeding up panel wiring.

• Minimize Wiring Errors: Pre-wired cables and clearly labeled terminals reduce the chance of miswiring.

• Organize Control Panels: Provides a neat and professional appearance by consolidating wiring.

• Simplify Troubleshooting: Clear terminal designations aid in quick identification and troubleshooting of connections.

• Features:

• 40-Pole (ZL-RTB40) / 48-Pole (ZL-RTB40-1): Offers a high number of connection points for various I/O signals. Note that the 48-pole version is sometimes referred to as "reduced-width" for space saving.

• DIN Rail Mountable: Designed for easy and secure mounting on standard 35mm DIN rails.

• Screw-Type Terminals: Provides robust and reliable connections for field wiring using standard screwdrivers.

• Compact Design: Helps save valuable panel space.

• Compatibility: Designed to work seamlessly with AutomationDirect PLCs (like DirectLogic, CLICK, Do-more BRX, Productivity Series) and their respective ZIPLink cables.

• Wire Range: Accommodates a wide range of wire sizes, typically 12-24 AWG solid or stranded copper conductors.

• Clear Markings: Terminal blocks are typically clearly labeled for easy identification of connections.

Product Parameters

(Note: There appears to be a slight variation between ZL-RTB40 and ZL-RTB40-1, particularly in pole count and voltage/current ratings. Always refer to the specific datasheet for the exact model you are using.)

Product Advantages

• Time and Cost Savings: Significantly reduces wiring labor and associated costs during panel assembly.

• Reduced Wiring Errors: Factory-assembled ZIPLink cables minimize the potential for miswiring compared to individual wire termination.

• Neat and Organized Panels: Creates a clean, professional, and easy-to-manage wiring layout within control cabinets.

• Faster Troubleshooting: Clearly labeled screw terminals and organized wiring simplify identification of circuits, speeding up diagnostics.

• Reliable Connections: Screw-type terminals provide secure and durable connections.

• Space Efficient: Compact DIN rail mountable design helps maximize panel space.

• Flexible Application: Compatible with a wide range of AutomationDirect PLCs and I/O modules.

Precautions

• Correct Voltage and Current Ratings: Always ensure that the voltage and current of your field devices and I/O signals do not exceed the maximum ratings of the ZL-RTB40/ZL-RTB40-1 module. Using a Class 2 power supply is often recommended.

• Proper Cable Selection: Ensure you use the correct ZIPLink pre-wired cable (e.g., ZL-CBL40, ZL-CBL40-1, ZL-CBL40-2) that is compatible with both your PLC I/O module and the ZL-RTB40 module.

• Wire Gauge: Adhere to the specified wire gauge range (12-24 AWG) and ensure proper wire stripping length for secure terminal connections.

• Screw Torque: Apply the recommended screw torque (4.4 in·lbs / 0.5 N·m) to prevent loose connections or damaged terminals.

• Environmental Conditions: Operate the module within its specified temperature range (0 to 60°C). Avoid excessive humidity or corrosive environments unless additional protection is provided.

• Mounting: Ensure the module is securely mounted on the DIN rail to prevent movement and potential wiring issues.

• Internal Wiring Only: Connecting cables for ZIPLink solutions are often intended for internal wiring within control panels and may not be suitable for external field wiring without additional protection.
