        Features:

        • Provides centralized time synchronization for the distributed Sequence of Events system with high timing accuracy.
        • Receives external reference time through an IRIG-B input and distributes absolute time using an RS-485 synchronization link.
        • Combines a 16-bit 10 MHz microprocessor with low power consumption for reliable continuous industrial operation.
        ABB SPTKM01 provides the timing foundation required for distributed Sequence of Events applications in industrial automation systems. Accurate time synchronization allows event records from different locations to be correlated correctly, helping operators analyze process conditions and system responses with confidence. Reliable timing also supports efficient diagnostics following equipment or process events.

        As the SOE time keeper master, SPTKM01 receives reference time from an external source through the IRIG-B interface connected by NTST01. The module then distributes absolute time to the distributed network through an RS-485 synchronization link, ensuring coordinated operation with the SPSEM11 module and other connected devices. This architecture supports consistent event recording throughout the control system.

        ABB SPTKM01 integrates a 16-bit microprocessor operating at 10 MHz while requiring only a typical 300 mA from a 5 VDC power supply. Designed for operation between 0 °C and 70 °C, the module delivers dependable performance in industrial environments where accurate time synchronization is essential for sequence of events monitoring and reporting.

        The SPTKM01 ABB SOE Time Keeper Master may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

        Description
        ABB SPTKM01 functions as the SOE time keeper master within the distributed Sequence of Events architecture. The module provides precise time information to the SPSEM11 module while distributing synchronized timing throughout the entire SOE system. Accurate system time enables reliable recording and sequencing of digital events across multiple control nodes.

        To obtain a stable time reference, SPTKM01 connects to an external receiver through an IRIG-B time code link using the DC level shift format provided by the NTST01 interface. After receiving the reference signal, the module distributes absolute time to the rest of the system through an RS-485 time synchronization link operating at 62.5 kbaud. This communication method supports consistent synchronization across the distributed network.

        ABB SPTKM01 delivers high timing performance with synchronization accuracy of ±10 μsec and absolute time accuracy of ±1 msec when communicating with the SPSEM11 module. The module incorporates a 16-bit microprocessor operating at 10 MHz to process timing information efficiently while maintaining dependable synchronization for Sequence of Events applications.

        Operating from a 5 VDC power supply with a tolerance of ±5% and a typical current consumption of 300 mA, SPTKM01 is suitable for continuous industrial operation. The module supports ambient temperatures from 0 °C to 70 °C (32 °F to 158 °F), allowing reliable performance in control cabinets where accurate event timing is essential for monitoring, reporting, and system coordination.
