Yokogawa expands controller range

Three additions have been made to the UTAdvanced controller series from Yokogawa Electric Corp. The UP55A and UP35A program controllers and the UM33A digital indicator with alarms.

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 stand-alone devices like 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 rising need for such controllers in other types of applications, Yokogawa 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.

UP55A and UP35A program controllers provide for support of the PROFIBUS-DP and CC-Link industrial communication protocols to allows these controllers to be connected with a wider range of PLCs, which are often mounted on other devices, and gives customers the flexibility to build an optimal multivendor system.

The processing of program data from PLCs has been speeded up in response to the needs of customers who wish to program patterns at a PLC.

The UM33A digital indicator 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.

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 widely used with field devices; PROFIBUS DP and CC-Link are registered trademarks of the PROFIBUS User Organisation and the CC-Link Partner Association, respectively.

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.
