Product Description

The 1738-OB8EM23 module is a POINT I/O 8-channel digital output module from Allen-Bradley, designed for industrial automation applications. It provides eight isolated 24V DC sinking outputs, directly interfacing with sensors, actuators, and other field devices. This module integrates seamlessly with POINT I/O systems, supporting expansion through adjacent modules and communication via EtherNet/IP for real-time control. Operating within a 24V DC power range (±10% tolerance), it functions reliably in harsh environments with an operational temperature range of -20°C to 55°C. Ideal for manufacturing and process industries, its compact design ensures space efficiency while offering high noise immunity and diagnostic capabilities. Key advantages include easy configurability and modular scalability, though it requires compatible Allen-Bradley controllers for full functionality. The module excludes battery or display components, focusing solely on robust I/O performance.
