Description
Product Description
The 1771-OVN digital output module from Allen-Bradley is a low-true DC sink output interface designed for PLC-5 and Bulletin 1771 programmable controller systems. This module provides reliable discrete output control for industrial automation applications requiring high-density DC signal switching.
Configured with 32 sinking outputs divided into four isolated groups of eight channels, the module is suitable for interfacing with field devices such as relays, pilot lamps, solenoids, and low-voltage DC actuators. The Allen-Bradley 1771-OVN supports installation in both local and remote I/O chassis environments and is compatible with rack-mounted PLC-5 architectures.
The module operates within a 10 to 30 VDC output range and uses low-true logic for field signal operation. Designed for dependable long-term performance, it includes conformal coating protection for improved resistance against moisture and industrial contaminants.
