Overview
The pulse converter is available in three versions:
• SICLOCK PCON
• SICLOCK EOPC
• SICLOCK GPS1000 PS
SICLOCK GPS1000 PS, SICLOCK PCON and
SICLOCK EOPC pulse converters
SICLOCK PCON pulse converter
The SICLOCK
PCON is a single-channel, electrical-optical pulse
converter. It enables electrical and optical time frames and
pulses to be distributed.
The device has three inputs for electrical signals (RS 422,
RS 232, etc.), one optical input, as well as five electrical outputs
and one optical output. By using fiber-optic cables, longer
distances can be bridged with very high interference immunity.
The SICLOCK PCON pulse converter can be operated in two
modes:
•
In transparent mode, the input signal is output at all outputs
without any change.
•
In pulse mode, an edge change at the input triggers a pulse
with parameterizable length at all outputs.
The device is easily parameterized by means of DIP switches
located directly on the device.

SICLOCK EOPC pulse converter
The SICLOCK EOPC is an electrical-optical converter and hub.
It features two electrical inputs, which can be alternatively used,
and transfers these signals at its 32 fiber-optic outputs. This
pulse converter is therefore the ideal choice for applications with
numerous nodes with optical pulse interface which have to be
synchronized.
SICLOCK GPS1000 PS pulse converter
The SICLOCK GPS1000 PS pulse converter is always used
when a SICLOCK wireless receiver is used as stand-alone unit,
i.e. without a central plant clock. It fulfills two main functions:
•
On the one hand, the pulse converter is used as an energy
source for SICLOCK wireless receivers.
•
On the other hand, the device is used as a level converter.
The time signal received at input 11/12 is output as RS 232 level
at the Sub-D interface X3.
