Main Functions
Linear Output Range
lset
A linear output range can be set as required. A value corresponding
to the maximum output value and that corresponding to the minimum
output value can be set.
Remote/Local Selection
r-l
Select remote programming when performing all settings through the
host devices and select local programming when performing settings
through key operation.
I
BCD Output Timing Chart
A request signal from an external device (such as a Programmable Controller) is required to read BCD data.
Single Sampling Data Output
Approximately 30 ms after the REQ signal rises, a sample is taken and the DATA VALID signal is output. Read the data when the DATA VALID
signal is ON.
The DATA VALID signal will turn OFF in 40 ms, and then in 16 ms, the data will go OFF.
Models with a BCD output have an open collector output configuration so that wired-OR connection is possible.
Continuous Data Output
The K3NC outputs each measurement at an interval of 64 ms when
a REQ signal is ON continuously.
