Toyo Keiki TMW Series Multi Power Meter

Product Made In Japan
Manufacturer: Toyo Keiki
Model: TMW Series

Features

Industry-first in adopting “Graphic LCD”
The adoption of graphic LCD makes the measurement display screen different from conventional types.
“Display of time series” using a trend graph
Previous measurements (power, etc ) are displayed on a trend graph in time series.
This shows the variation trend of the measurements at a glance.
Various measurement displays
Not only the conventional straight bar graph but also an arc-shaped bar graph are available. They can be switched.
Up to 10 elements are displayed collectively
The display screen can be switched among one-element, four-element, and ten-element screens in real time. (See page 6.)
On the ten-element screen, the measurement items of up to 35 elements can be displayed by scrolling the screen (3P4W specification).
Arbitrary VT and CT settings are possible
The VT and CT values on the primary side can be set arbitrarily to support special VT and CT.
“Easy setting” (Setting support function provided)
In the setting mode, the operation instruction is displayed at the bottom of the display screen. Therefore, setting is possible without the manual.

④ Output specifications

Output type	Specification
Analog output	DC4～20mA 0～550Ω DC1～5V 600Ω～∞ MAX.4CH
Pulse output	Active energy or Reactive energy DC125V, AC125V 0.1A MAX.2CH

Transmission output	RS-485 Protocol: MODBUS Baudrate: 2400, 4800, 9600, 19.2k, 38.4kbps

(Note) Up to two point outputs are available for pulse output and alarm output.
Either of transmission output and pulse output (alarm output) is to be selected (see type name system).
Pulse output is output asynchronously with the display update interval.
Note that a time difference may be generated between the indicated value and the pulse number.

⑤ Remote input specification

The measurement items of the main display can be changed by applying a voltage from outside (Display screen 1 or Display screen 2).
Apply a voltage of 80 to 264 VAC or 80 to 143 VDC to the external input terminal (for 0.5 seconds or more). Each time a voltage is applied, the next item is selected.
