Allen-Bradley 1738-OV4EM12 Digital Output Module

The Allen-Bradley 1738-OV4EM12 Series A ArmorPoint digital output module provides four sinking 24V DC outputs in a compact ArmorPoint package for Rockwell Automation distributed I/O. It delivers a total of up to 2.0 A per module, with a maximum of 1.0 A per channel, and uses DC micro (M12) connectors for rugged field wiring. As part of the ArmorPoint family, this module is designed for ArmorPoint I/O networks and interfaces with compatible Rockwell controllers to switch 24V loads in automation applications. Each output is a sinking channel, suitable for driving DC loads such as solenoids, relays, or small actuators when connected to a +24V supply. The unit is specified for nominal 24V DC operation with an operating range of 10–28.8V DC, and it is identified as Series A (SER: A) within the AB 1738 ArmorPoint lineup for remote, decentralized control in space-constrained or harsh industrial environments.
