Mini Power Relay (Plug-In Terminal Type) Performance
2-color display: red and green
For the type featuring a comparison output function (Series K3MA-J-A2), the display color can be changed from green to red (or red to green) in accordance with the comparison output operation to be compared to the preset reference value. The operating status of equipment can easily be checked even remotely by the change in display color.
For the type without a comparison output function (Series K3MA-J), red or green can be selected for the display color for the current value, and can be used to meet the display purposes/applications of the industrial site. (Display color cannot be changed based on comparison with reference values.)
Forced zero operation
Reference value adjustment, etc., and shifting from any value to 0 can be performed with a single action by operating the front keys.
Zero limit is a function whereby numbers that are the preset value or less and close to 0 are displayed as 0.
Example: When the display is set to the first decimal place, if the zero limit value is 2, values -0.2 to +0.2 will be displayed as 0.
This is effective when you do not wish to display negative values, wish to display values close to the input range minimum as 0, etc.
Multi-range input
One model covers DC voltage input signals and DC current input signals.
Input value can be converted to the desired value and displayed
Series K3MA-J includes a scaling function that can convert the display of input signals to the desired number.
Rising shift, reverse display, + to - display, etc., can all be freely adjusted.
Settable with actual input
When setting scaling, instead of inputting using the UP key and SHIFT key, the currently measured value can be specified as the set value. This function is convenient to use when wishing to perform settings while checking the operating state, etc.
Output type is freely selectable
There are 2 comparison outputs, OUT1 and OUT2.
Each comparison type can be selected from the following 3 types:
Upper limit
Upper/lower limit
Lower limit
