The Yokogawa UP550
program controller can store up to 30 program patterns. These program
controllers from the Yokogawa UP550 Series have a powerful control
capability and a user-friendly large numerical display.
The UP550 program
controller from Yokogawa features many standard functions which are
necessary for various control applications. All of these functions,
which include program setting function, control function, control
computation function, signal computation function, and more, can be
configured by using the keys on the front panel. The Yokogawa UP550
program controller has five types of control strategies and also an
overshoot suppressing function "SUPER" and a heating suppressing
function "SUPER 2" built in as standard, as well as an auto-tuning
function.
Main Features of the Yokogawa
UP550 Program Controller
- Extra-large digital
display allows the indicated values to be read even from a long
distance. LEDs of 20 mm height are used for the process variable
display. This is a five-digit display for higher resolution.
- User-friendly,
full-dot LCD display, capable of showing not only control setpoints (SPs)
and parameters but also program patterns and deviation (DV) trend
logs.
- Program setting
function with storage capacity for up to 30 program patterns and 300
program segments, allowing the controller to be used for a wide range
of heat-treatment applications.
- Five types of
control function, including single-loop control, cascade control, loop
control with PV autoselector, enabling the operator to start control
operation immediately after simply entering the settings.
- The program
pattern-2 retransmission function outputs a program pattern by way of
the retransmission output. This function is used in combination with
retransmission output setup parameter RET 1 or RET 2, for which
program pattern-2 should selected, and is used for pattern
transmission to another instrument(available for UP made 1, 2, 6 or
7).
- Parameters and
program patterns can be easily set using a personal computer.
("Parameter setting tool (model LL100)" sold separately is required.)
- Universal input and
output enables users to set or change freely the type of measured
inputs, measurement input range, type of control output, etc. from the
front panel.
- Contact inputs (up
to 7 points) and contact outputs (up to 7 points) can be employed and
functions can be assigned to each contact (the maximum number of
points varies depending on the specification code), with one
additional contact input available by specifying the appropriate
suffix code. Contact outputs can be increased up to eight.
- Various
communication function are provided. Communication is possible with
personal computer, programable logic controller, and other
controllers.
