Page 7: Functional Description
Functional description The SICLOCK PCON pulse converter enables electrical and optical distribution of time message frames and pulses. The advantage of data transmission via fiber-optic cables lies in the high degree of interference immunity and the ability to bridge great distances. The device has three electrical inputs and one optical input as well as five electrical outputs and one optical output. -
Page 8: Mounting And Installation
Mounting and installation The SICLOCK PCON is mounted on a 35mm DIN rail. The power supply is con- nected to terminals 14 and 15 of the terminal strip X1, and must generally be con- nected by a separate cable. The electrical inputs are also found on terminal strip X1. -
Page 9: Configuration
Configuration Block diagram The following diagram shows the connection of the input and output interfaces. All inputs are joined together internally by means of an OR function so that only one input is allowed to be connected for transmission of an explicit signal. The optical output is connected directly to the OR gate and cannot be influenced by the device parameter assignment. -
Page 10: Operating Modes
Operating modes 4.2.1 Transparent mode In transparent mode, the input signal is transmitted unchanged to the output. It is simply transferred to another electrical interface. This mode is always used to transfer telegrams, DCF77 and IRIG signals. 4.2.2 Pulse mode In this mode, a pulse with a constant pulse length is emitted at the output. - Page 11 • Triggering on the positive edge of the input signal. This type of triggering is only useful for a high-active input signal. A high-active pulse with the specified pulse length is generated at all electrical outputs. The output pulse can still be inverted, if required. Fig.

Page 12: Parameter Assignment
Parameter assignment All device settings can be made by means of the DIP switch S1 on the front of the housing. • The mode is set with switches 1 and 2. The following table lists all possible operating modes. Table 4-1 Switches 1 and 2 Switch 1 Switch 2... - Page 13 • Switch 5 can be used to invert the output signal of all electrical outputs. • The SICLOCK PCON provides the option of monitoring all inputs or the 120 VDC voltage output. For this purpose, a check is made to determine whether a status change takes place on the signal lines.

Page 14: Outputs
Outputs Voltage output The power supplies for the 24V/0.8A output and the 24 to 120 VDC/0.1A output must also be connected externally. The amplitude of the output voltage for the 24V/0.8A output corresponds to the connected supply voltage (12 to 30 VDC). For the 24 to 120 VDC/0.1 A output, the amplitude of the output voltage corre- sponds to the connected supply voltage (24 to 120 VDC) minus at least 4V. -
Page 15: Redundancy
Redundancy For highly reliable transmissions, two redundant transmission lines can be config- ured and the isolated voltage outputs of the two devices at the end of the line can be connected in parallel to the input of the device to be synchronized. If input signal monitoring is activated, the voltage outputs will be disabled when an alarm occurs. -
Page 16: Optical Input And Output
Optical input and output The SICLOCK PCON has an optical input and output. They are provided for connecting an 820nm multimode fiber-optic cable. Multimode The following table summarizes the launchable transmission power and the receiving sensitivity of the SICLOCK PCON for various types of glass fiber. The permissible line attenuation is returned as the result. -

Page 21: Esd Guidelines
ESD guidelines Electrostatic sensitive devices Definition All electronic modules are equipped with highly integrated circuits or components. Due to their design, these electronic components are highly sensitive to overvoltage and thus to the discharge of static electricity. These Electrostatic Sensitive Devices/modules are commonly referred to by the acronym ESD. -

Electrostatic charging of persons Charge Anyone who is not connected to the electrical potential of their surroundings can be electrostatically charged. The figure below shows the maximum electrostatic voltage which may build up on a person coming into contact with the materials indicated. These values correspond to IEC 801-2 specifications. -
Page 23: Fundamental Measures To Protect Against
Fundamental measures to protect against static discharge Make sure the grounding is good Make sure all persons, workplaces and packaging are sufficiently grounded when ESD components are being handled. In this manner, you avoid static discharge. Avoid direct contact You should only touch ESD components if this is unavoidable (for example, during maintenance work). -
