Description of business

TOYONAKA KEISOU CO. LTD. is a company specializing in development and manufacture of wire-saving devices and systems that reduce wiring and cables required for monitoring, control and measurement of electric contact signals, analog signals and other signals. Our corporate philosophy is to provide support for our devices and systems as long as they are used by customers.

Products and Technologies

Our wire-saving systems can save energy and labor as well

Visualization of industrial information by means of wire-saving multiplex transmission (Universal Line)

Taiwan High Speed Rail lines

●Universal LineThis system can transmit freely electric integrated signals, contact signals and analog signals via a normal single-pair (two-wire) line. Signal transmission at long-distance, wide-area and multi-location is implemented through time division multiplexing. Due to the unique noise immunity, this system is employed for electric substation monitoring on Taiwan High Speed Rail lines.

Smart Power 24

●Smart Power 24Implementation of further wire-saving based on Universal Line. We made possible individual monitoring, control and measurement at up to 256 locations, while supplying power of DC 24 V.

Multi-location temperature measurement and monitoring system

Multi-location temperature management systems using Universal Line with simple wiring make possible temperature measurement and monitoring at up to 2,000 locations and long-term (10 year) logging. Multi-location temperature measurement, monitoring and management are performed via parallel connection of two wires using multiplex transmission. Temperature measurement is possible at up to 2,000 locations using time division polling (changeover by 8 locations); the more locations are involved in measurement, the lower is wiring cost.

Smart Power 24

This system uses general-purpose wires to combine power supply of DC 24 V with data transmission. With this unique scheme, two wires can, in addition to power supply, carry diverse information about contact control output, monitoring input or analog measurement.

The system is configured of smart-power units - master station and slave stations. Cables of various types such as VCTF, VVF and IV can be used for wiring; in doing so, information can be transmitted bi-directionally on the same wires, simultaneously with power supply.

Power supply capacity can be increased from 5 A to 30 A by increment of 5 A. Current of about 500 mA can be drawn from supply terminals of every slave station; contact monitoring information can be inputted for up to 256 contacts, and contact control outputs can cover up to 256 locations. Thus various monitoring and control become possible across a wide area using just two wires.

< Merits >
●Usage of wires, pipes, ducts and other components as well as space can be reduced!
●No work design is needed, and additional construction cost can be cut dramatically, while construction period can be shortened!
