Yokogawa Electric has released three additions to the UTAdvanced controller series: the UP55A and UP35A program controllers and the UM33A digital indicator with alarms.

Completing the UTAdvanced series, these new products give customers greater choice in configuring systems and support a wider range of applications.

Indicating controllers are instruments that measure and display temperature, pressure, flow rate and other types of data and also display data on equipment operation.

They are mounted on, and control the operation of, relatively small-scale standalone devices such as industrial furnaces and semiconductor manufacturing machines.

The UTAdvanced controllers were first developed and introduced by Yokogawa in 2009 and have been primarily used in applications that involve the control of fixed values within preset targets.

In response to the need for such controllers in other types of applications, the company has developed three new products.

The UP55A and UP35A program controllers carry out programmed pattern control (control over time according to a preset pattern) and the UM33A digital indicator outputs an alarm when an input signal reaches a preset value.

The UP55A and UP35A program controllers support the Profibus-DP and CC-Link industrial communication protocols.

This allows the controllers to be connected with a wider range of programmable logic controllers (PLCs), which are often mounted on other devices, and gives customers the flexibility to build an optimal multivendor system.

In response to the needs of customers who want to program patterns at a PLC, the processing of program data from PLCs is now faster.

The UM33A digital indicator now has eight alarm outputs and eight screen display points – twice the number of the previous model.

A dedicated program eases the task of entering alarm values and other information, eliminating the need to input them using the keys on the front panel of each device.

UTAdvanced digital indicating controllers come standard with a sequence control function based on the ladder logic programming language, which is widely used by engineers.

This product series is claimed to improve design efficiency and reduce costs by eliminating the need for relays and other types of peripheral devices.

These controllers can be used to build systems that rely on various industrial communication protocols such as Profibus-DP and CC-Link.

These standard communication protocols are often used with field devices; Profibus-DP and CC-Link are registered trademarks of the Profibus User Organisation and the CC-Link Partner Association respectively.

Key target markets include production-line operations in industries such as electrical equipment, machinery, chemicals, foods, semiconductors and automobiles, as well as companies that design, build and maintain air conditioning, power and other types of in-plant facilities.

Applications include the measurement, display and control of temperature, pressure and flow rate in research and development facilities and manufacturing operations, including heat treatment, washing and sterilising.
