Brochure

Three types of digital panel indicators in the K3MA series cover
a wide range of applications. Each indicator accepts a wide
range of power supplies, and indicator versions are available
with or without control functionality.
Each indicator is compact, with a depth of just 80mm from the
edge of the faceplate to the rear. All models conform to U.S.
and Canadian requirements under the Component Recognition
Program of UL with CE marking. In addition, self-adhesive
labels containing a wide range of engineering units are
included with each indicator.
K3MA-J
This indicator accepts all standard process signals, including
input currents (0 to 20mA; 4 to 20mA) and input voltages
(from 0 to 5V; 1 to 5V; ±5V and ±10V), and converts these
inputs into whichever process value is required.
K3MA-L
This indicator handles multiple inputs, including two types
of platinum-resistance thermometers and ten types of
thermocouples, to provide precise temperature read-outs.
It also features a temperature input shift, which is equivalent
to the setting value supporting all points within the sensor
measurement range (from –1999 to 9999).
K3MA-F
This indicator accepts various input devices (which can be
connected as standard contact NPN, PNP or voltage pulse
inputs), and provides accurate data for frequency/rate
measurements. This indicator has a sensor power supply
as standard.
