LTRON 48 |
|
|
LTRON-48 is Microprocessor based
1/8 DIN Indicator/ On-Off
controller with Single display.
The instruments are innovative
in terms of compact size. It has
full key-board based operation
for programming inputs, ranges,
decimal point, linear or
square-root input selection and
calibration.
The instrument’s compact and
highly functional fascia
consists of a 4-digit 7-segment
LED display and 4-key membrane
keyboard for
programming / parameter selection
purposes. |

LTRON 40 |
|
|
LTRON-40 Indicators and On-Off
Controllers are part of Lectrotek’s
LTRON-series MICROPROCESSOR-based
Process Measurement and Control
products. The instruments are
innovative in terms of compact size
(1/4 DIN & 1/8 DIN versions) and
cost-effective, yet full-featured in
terms of ease of use,
programmability, optional
communication port and
re-transmission signal output. It
has full keyboard based operation
for programming inputs, ranges,
decimal point, linear or square root
input selection and calibration. |
|
|
|
|
|
The instrument’s compact and highly
functional fascia consists of a 4
digit 7-segment LED display and
4-key membrane keyboard for
programming/parameter selection
purposes. RS-232 or Rs-485 ports are
optional for communication with
DAS/SCADA systems. A 4-20 mA
re-transmission signal is also
optional, and can be used for
recording purposes or remote signal
transmission to DAS/PLC/DCS systems. |
