“The use of PTP converters may enable cost savings by removing the need to install separate 1PPS cabling and provide new redundancy options for the substation time source”
– Dylan Jenkins, GermanyTekron’s PTP Translator is a compact DIN-rail mount device that translates PTP (default, power and telecommunications profiles) to legacy time codes such as IRIG-B, DCF77 or user defined pulses. The PTP Translator enables you to migrate to PTP without having to incur the expense of replacing all your equipment that don’t support PTP.
Key Features:
- Compact DIN-rail mounting form factor
- Allows IED’s equipped with IRIG-B, Pulse or other common time code inputs to conveniently access a PTP network
- Intuitive Configuration Software
- Enhanced Security and encryption that exceed NERC CIP requirements
Input/Output Signals:
- TTL output
- Supports C37.118.1
- RJ45 Ethernet/ST multi-mode Fiber Ethernet
- ST Fiber output
