Siemens 6ES7134-4GD00-0AB0 Digital Output Module

The Siemens 6ES7134-4GD00-0AB0 Digital Output Module is a 16-channel transistor output module for SIMATIC S7-300 (SM134) that converts PLC logic signals into discrete drive currents for external field devices. Each channel provides a 24 V DC transistor (PNP) output rated at 0.5 A, with a total module output capability around 8 A; outputs are optically isolated from the PLC logic and feature LED indicators for channel status. The module mounts in a PB-bus rack in the S7-300 chassis, carries an IP20 enclosure rating, and is designed for industrial temperature operation, making it suitable for controlling actuators such as relays, contactors, solenoids, pilot lights, and small motors in manufacturing lines, packaging, conveyors, process plants, and building automation. Common replacements include Siemens 6ES7134-4HD00-0AB0, 6ES7134-4HE00-0AB0, and 6ES7134-4JF00-0AB0.
