6ES7338-4BC01-0AB0 SIEMENS SIMATIC S7-300, Signal Module

SIEMENS 6ES7338-4BC01-0AB0 SIMATIC S7-300, Signal Module :

SIMATIC S7-300, Signal module for 3 SSI encoders for reading in the position value with 2 FREEZE inputs, 1x 20-pole Supports isochronous mode.

The 6ES7338-4BC01-0AB0 is a SM 338 position input module from Siemens' SIMATIC S7-300 series, designed for precise position detection in industrial automation. This module supports three SSI (Synchronous Serial Interface) encoders, providing 13-bit resolution positioning data with two FREEZE input terminals for value locking. It integrates clock synchronization and is housed in a compact form factor (40 mm width, 125 mm height). The module connects via a 20-pin front connector and is suitable for applications requiring dynamic position feedback, such as CNC machines, automated assembly lines, and industrial robots.
