The DTS 4163.grandmaster is a PTP grandmaster specifically designed for digital substations according to IEC 61850. With its high precision and seamless redundant operation, it offers a high degree of reliability and availability.
PTP Grandmaster for IEC 61850 Digital Substations
The DTS 4163 is a primary reference time clock (PRTC) and PTP grandmaster according to IEEE 1588-2008 / PTPv2, with IEEE 1588-2019 / PTPv2.1 compability, for the highly accurate synchronization of clients.
PRP/HSR Support
The DTS 4163 features a pair of redundant interfaces (PRP/HSR) to directly connect the device as a DAN (dual attached node) with full 1Gbps bandwidth.
Full Gigabit Ethernet
Offers 4 fully PTP-capable Gigabit Ethernet ports (RJ45 or SFP), each supporting 1-step/2-step, multicast/unicast, IPv4/IPv6, Layer 2, and independent domain/profile configurations — ideal for modern segmented networks.
Cyber Security
Designed with security in mind, the system features secure boot, encrypted user data, and signed firmware. It supports secure access via SSH, SCP, SFTP and HTTPS (coming soon), according to IEC 62443-4-2 standards.
High-Performance NTP Server
The DTS 4163 can reply to more than 10‘000 NTP and SNTP requests per second (up to 600‘000 clients depending on NTP client configuration).
GNSS Receiver
The DTS 4163 can simultaneously receive all GNSS L1 systems (GPS+QZSS/SBAS, Galileo, GLONASS, BeiDou), guaranteeing utmost accuracy and availability.
Boundary Clock Capability
The DTS 4163 can be used as boundary clock to bridge different time domains using two external PTP servers and serve up to four other domains with clients.
Oscillator Options
The DTS 4163 offers different oscillator options, enabling enhanced holdover performance and long-term stability tailored to application needs.
Legacy Outputs
The DTS 4163 outputs support many legacy signals such as IRIG, ToD, DCF, pulse, and frequency.
Network Management System
The DTS 4163.grandmaster can be fully monitored, configured and controlled using the Mobatime Network Management System software (MOBA-NMS).
