Siemens 6FX1138-4BA01 VER B 570 384 9101.01 CPU Module

Siemens 6FX1138-4BA01 VER B is a SINUMERIK 800 mixed I/O module that delivers 4 analog outputs and 16 digital inputs plus 16 digital outputs, enabling compact, on-rack interface between a CNC control and its peripheral devices. Identified by part number 6FX1138-4BA01 and also cataloged under 570 384 9101.01, this hardware revision VER B is intended for SINUMERIK 800 installations and is commonly found in machine tool retrofits or replacements where reliable analog and digital I/O are required. As a mixed I/O module, it consolidates signal conditioning for both analog and digital channels in a single card, supporting applications such as controlling analog actuators, reading limit switches, sensors, and interlocks, and signaling back to the controller via the SINUMERIK 800 backplane. Typically deployed in CNC milling, turning, or machining centers that rely on SINUMERIK 800 controllers, this module provides a rugged, backplane-compatible interface intended to maintain precise I/O timing and robust operation within rack configurations.
