Available. The Siemens 6ES7138-4DB03-0AB0 is a compact electronic module designed for the SIMATIC DP system, specifically tailored for the ET 200S series. This module facilitates the connection of absolute value encoders using the SSI (Synchronous Serial Interface) protocol, supporting 25-bit data communication at a speed of 1 MHz. With its slim 15 mm width, it is ideal for space-constrained configurations. The module operates with a 24 V DC supply voltage and features reverse polarity protection. It includes one digital input and provides a 24 V encoder supply with short-circuit protection, capable of delivering up to 500 mA. The module's dimensions are 15 x 81 x 52 mm, and it weighs approximately 40 grams. This device is suitable for applications requiring precise and efficient encoder connectivity in industrial automation systems.
