Excellent PLC
Product Introduction
The Allen-Bradley 1771-OVN Low True Output Module is a digital output module designed for use within PLC-5 control systems, providing reliable switching control for field devices in industrial automation applications. It is specifically configured with low-true (sink) outputs, making it suitable for controlling loads that require current sinking operation.
This module offers 32 digital outputs organized into four groups of eight, allowing efficient management of multiple field devices such as relays, solenoids, and indicator lamps. Its design ensures consistent performance in demanding industrial environments where stable and responsive output control is required.
With a robust construction and compatibility with the 1771 I/O platform, the module integrates seamlessly into existing PLC-5 systems. It supports flexible wiring configurations and provides dependable operation in high-vibration and electrically noisy environments.
