2Product Scope
RT411 - Time Signal Distributor expands the number of electrical/optical signal outputs
from a GPS/GNSS Clock. The equipment is ruggedized and specifically designed for
operation and to be part of the large scale electrical fixed installations, as electrical
power generation installations, electrical substations and electrical utilities control
systems.
RT411 multiplies IRIG-B demodulated, PPS or any signal with a voltage up to 5 Vdc, and
frequencies up to 5 MHz, through the electrical and optical outputs. The equipment’s
time accuracy is based on the accuracy of the time reference source been used.
The equipment has up to 10 electrical outputs with a 150 mA individual supply capacity
and up to 10 optical outputs for multimode fiber and ST connector.
It also has indicators for monitoring the received time reference signal and the power
supply.

4Standards Compliance
The device has undergone a range of extensive testing and certification processes to
ensure and prove compatibility with all target markets.
Compliance with the European Commission Directive on EMC and LVD is demonstrated
using a Technical File.

•EMC Compliance: Compliance with IEC 60255-26:2013 was used to establish
conformity.
•Product Safety: Compliance with IEC 61010-1:2010 was used to establish
conformity.
•Protective Class: Protective Class I. This equipment requires a protective
conductor (ground) to ensure user safety.
•Installation category: Compliance with IEC 61010-1:2010 Overvoltage Category II
•Environment: IEC 60068-2-1, IEC 60068-2-2, IEC 60068-2-30, IEC 60068-2-14, IEC
60255-21-1, IEC 60255-21-2. The equipment is intended for indoor use only. If it is
