Allen-Bradley 1771-OBN Output Module

The Allen-Bradley 1771-OBN is a DC digital output module compatible with the PLC-5 family of programmable logic controllers. It features 32 sourcing output channels, organized into four groups of eight, allowing for efficient control of multiple devices. Each output channel operates with a voltage range of 10-30V DC and can source up to 0.5 A, suitable for driving various actuators and indicators. The module includes internal clamping diodes for surge suppression, protecting the output transistors from high-voltage transients. It is designed for easy installation into 1771 I/O chassis, with compatibility considerations for specific chassis models. The 1771-OBN supports 1/2-slot addressing and requires careful placement in the I/O chassis to ensure proper operation. This module is ideal for applications requiring high-density DC output control in industrial environments.
