PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1771-OWNA is a PLC-5 digital output module designed for contact switching applications. This module features 32 normally open contact outputs arranged in four separate groups of eight channels each. The unit operates with a nominal backplane current of 1.8 A and a maximum current of 2.5 A. A factory conformal coat provides environmental protection for internal module circuitry.
The 1771-OWNA operates with alternating current switching voltages ranging from 24 to 138 V AC. It also supports direct current load switching across 24 to 125 V DC. The module supports a maximum continuous current of 12 A at 45 degrees Celsius. Individual output circuits handle up to 0.25 A at 120 V or 1 A at 30 V. The hardware mounts directly into an Allen-Bradley 1771 universal I/O chassis slot.
