Product Introduction
The Allen-Bradley 1771-OBD Digital DC Output Module is a high-performance DC output module designed for the PLC-5 1771 I/O system by Allen-Bradley. It provides reliable control of DC-powered field devices, converting PLC digital signals into precise DC outputs for industrial automation applications.
This module features 16 output points, each capable of handling up to 2 A resistive current and pilot duty operation. The total module current is rated at 8 A, and it supports a 10–60 VDC output range. Designed for fast and stable operation, it draws 400 mA from the 5 VDC backplane, ensuring efficient integration with other 1771 modules.
Installed in a 1771 I/O chassis, the 1771-OBD module is ideal for controlling DC motors, solenoids, relays, and other DC devices in industrial systems where precise digital output is required.
