The Yokogawa UP550 temperature controller can store up to 30 program patterns. The Yokogawa UP550
temperature controller has a powerful control capability and a user-friendly large numerical display.
The Yokogawa UP550 temperature controller 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 Yokogawa UP550 temperature controller's front panel.
The Yokogawa UP550 temperature 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 Temperature 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 temperature 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, programmable
logic controller, and other controllers.
