Product details

The 6ES7138-4DA03-0AB0 is a single-channel counter module for the Siemens ET 200SP distributed I/O system. It packs a 32-bit counter (up to 100 kHz), one digital input, and one digital output into a 15 mm-wide slice, saving panel space without sacrificing diagnostics. Powered at 24 V DC with reverse-polarity protection.

Input and output characteristics

The digital input is switched for signal '1' from +11 V up to L+ (-1 V), typical sinking 9 mA. The output is rated 24 V DC, 500 mA maximum with short-circuit protection; switching frequency reaches 100 Hz resistive load. For sensor interfacing, it supports 2-wire sensors (Type 2) and directly controls other digital inputs.

Module occupies 15 mm rail width, 81 mm height, 52 mm depth. Unshielded cable runs up to 600 m and shielded up to 1 000 m.

Frequently asked questions

What is the width and depth of this module?

The module is 15 mm wide, 81 mm high, and 52 mm deep. It fits a standard ET 200SP rail slot.

Will the 6ES7138-4DA03-0AB0 replace the 6AG1123-2DB03-2AX0 without rewiring?

No, the 6AG1123-2DB03-2AX0 is a SIPLUS variant of a different module type. You must confirm that the I/O function, voltage, and bus interface match your application before swapping.
