Recently introduced, 8 new output code types are now available including 4 analog outputs, 2 analog outputs, and 4 contact output modes.
Analog output signals can be 4 to 20mA DC or 1 to 5V DC with output and control input combinations including: 4 analog channel, 2 analog channel + 2 contact output, and 2 analog channel + 1 contact output + 1 contact input modes.
Contact outputs can be allocated for alarm or pulse output use, and new output options include 4 contact output and 3 contact output + Modbus modes (for more information, see Table 1 for a list of new specifications).
Key Functionality and Features
This section introduces the model’s original specifications and newly added features.
1. Measured variables
2. LCD display
The top 3 lines display instantaneous values for readings such as voltage, current, power and others. Character size has been maximized for improved visibility. In a design that facilitates daily monitoring by making it easy to assess current values with a single glance, the numerical readouts are accompanied by 3 bar graphs, each of which is linked to the adjacent display value.
The bottom line of the display provides text-based information. It usually shows accumulated energy count and is automatically switched to an alarm indicator. The flashing text tells the user which variable is in an alarm mode. It also helps the user in programming the monitor by indicating menu items in text format making it easy to navigate through the programming menu without consulting instruction manuals. The new 53U specifications also give users the ability to set the display refresh rate, allowing the process to be slowed so that measured values can be easily noted by hand.
