Siemens 6DS1124-8AA TELEPERM M Clock Pulse Generator Module

Product Overview

The Siemens 6DS1124-8AA, known within the TELEPERM ecosystem as the Taktgeberbaugruppe (clock pulse generator module), serves as the central timing authority for the Siemens TELEPERM M distributed control system. This specialized module generates and distributes precisely synchronized clock pulses across the entire system backplane, ensuring that all processors, I/O modules, and functional units operate in perfect temporal harmony. Within the TELEPERM M architecture, the Siemens 6DS1124-8AA functions as the system’s “heartbeat”—a critical component that establishes the common time base required for deterministic control execution, accurate event sequence recording, and coordinated data acquisition across distributed I/O stations .

The Siemens 6DS1124-8AA is built around a high-stability crystal oscillator that delivers exceptionally low timing jitter and minimal frequency drift over temperature variations. This precision timing reference is distributed through the TELEPERM M backplane via dedicated low-skew synchronization lines, ensuring that all modules within the rack share an identical time base regardless of their physical slot position . As the TELEPERM M series has long been discontinued, the Siemens 6DS1124-8AA is now maintained exclusively through the legacy spare parts channel, making it a vital asset for facilities operating existing TELEPERM M installations where system migration is not yet feasible . The module’s role in maintaining system-wide synchronization is indispensable for applications that demand accurate sequence-of-events logging and tightly coordinated multi-loop control.
