Technical Specifications

Installation Guidelines

• Ensure the controller power is disconnected before installing or removing the module to prevent electrical damage.
• Mount the module on a standard 35mm DIN rail, ensuring it is securely locked into the backplane connector.
• Maintain adequate clearance around the module to allow for proper airflow and heat dissipation.
• Use shielded cabling for output signals to minimize electromagnetic interference (EMI) in high-noise industrial environments.
• Verify that the external power supply connected to the output terminals matches the 24V DC specification.

FAQ

What is the primary function of the 1762-OB8?

The 1762-OB8 is an expansion I/O module that adds eight digital DC output points to a MicroLogix 1200 or 1500 PLC system, allowing the controller to drive external DC-powered loads.

Is this module compatible with all MicroLogix controllers?

The 1762-OB8 is specifically designed for the MicroLogix 1200 and 1500 expansion I/O bus. It is not compatible with MicroLogix 1000 or 1100 series controllers.

What is the required power supply for the outputs?

The module operates within a voltage range of 20.4 to 26.4V DC. Ensure your field power supply is regulated and falls within this range for optimal performance.
