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.","metaTitle":"Siemens 6ES7138-4DA03-0AB0 ET 200SP Counter Module","metaDescription":"Siemens SIMATIC ET 200SP counter/digital I/O module, 1x 32-bit 100 kHz, 24 V, 15 mm wide, diagnostics.
