Intended use

The Multi Signal Converter is a device, which can be used to convert and distribute DCF signals.

However, it can also be used for other types of signals. The limitation is given by the frequency of the signals and the signal form. Ideally, the device is used for digital signals. See also chapter 7 Technical data.

Please refer to section – 3.3 Function description – for a detailed function description.

 Observe operating safety!

• Vorsicht! Never open the housing of the device! This could cause an electric short or even a fire, which would damage your device. Do not modify your device!
• The device is not intended for use by persons (including children) with limited physical, sensory, or mental capacities or a lack of experience and/or knowledge.
• Keep packaging such as plastic films away from children. There is the risk of suffocation if misused.

Consider the installation site!

• To avoid any operating problems, keep the device away from moisture and avoid dust, heat, and direct sunlight. Do not use the device outdoors.
• The Multi Signal Converter is designed for DIN rails and should only be operated installed on a DIN rail.

Danger! Make sure
that you wait before using the device after any transport until the device has reached the ambient air temperature. Great fluctuations in temperature or humidity may lead to moisture within the device caused by condensation, which can cause a short.

Observe electromagnetic compatibility!

Vorsicht! The device complies with the requirements of EMC directive 2004/108/EC and 96/48/EC

Current – fiber-optic converter DCF IN → Optical transmission to 2. Multi Signal Converter
Voltage – voltage converter TTL IN → 24V PLC
Voltage – current converter Clock line (e.g. DCF active) → Current Loop OUT
Data – fiber-optic converter RS 422 → Optical transmission to 2. Multi Signal Converter
Fiber Optic – data converter Fiber Optic FO IN → RS 422 OUT resp. TTL OUT
