Description

The Allen-Bradley 1761-L16BWB is a compact MicroLogix 1000 programmable controller engineered for small-scale automation and discrete I/O control tasks. This all-in-one unit integrates the processor, power supply, and input/output circuitry into a single, space-efficient housing, making it suitable for applications where panel space is limited.

Features

• Integrated 16-point I/O configuration: 10 DC inputs and 6 relay outputs.
• Supports both sinking and sourcing input configurations for flexible wiring.
• Relay outputs support a wide range of voltages (5 to 125V DC and 5 to 264V AC).
• Designed for high reliability with a minimum of 50,000 power cycles.
• Compact footprint suitable for DIN-rail or panel mounting.

Applications

This controller is typically utilized in standalone machine control, small conveyor systems, packaging equipment, and basic process monitoring where a cost-effective, fixed-configuration PLC is required.

Technical Specifications

Installation Guidelines

• Ensure the controller is mounted in an environment free from excessive dust, moisture, and corrosive gases.
• Maintain adequate clearance around the unit to facilitate proper ventilation and prevent overheating.
• Always disconnect power before installing or removing wiring to prevent electrical shock or damage to the module.
• Use shielded cables for I/O signals to minimize electromagnetic interference (EMI) in industrial environments.
• Ensure proper grounding of the controller chassis to a common ground point to maintain signal integrity.
• Follow standard ESD (Electrostatic Discharge) precautions when handling the module to protect internal components.

FAQ

What is the primary power requirement for the 1761-L16BWB?
The unit operates on 24V DC power, with an acceptable operating range of 20.4 to 26.4V DC.

Does this controller support expansion modules?
The MicroLogix 1000 series (including the 1761-L16BWB) is a fixed-configuration controller and does not support additional I/O expansion modules.
