CAUTION or WARNING:
Electrical Shock Hazard
All safety related instructions that appear in the manual must be
observed to ensure personal safety and to prevent damage to either
the instrument or the system. If the instrument is used in a manner
not specified by the manufacturer, the protection provided by the
equipment may be impaired.
PRESENTATION
N1500 is a universal process indicator which accepts a large variety
of input signals and sensors. A six-digit LED display shows measured
value and all programming parameters.
Instrument configuration is achieved from the keypad, without any
hardware change. Thus, the selection of input type and alarms
modes, besides other special functions, are accessed and defined
from the frontal keypad.
The user should read this manual thoroughly before using the
instrument. It must be handled with care and should be used
accordingly for best results.
Some of the features are:
• Universal input: Pt100, thermocouples, 4-20 mA, 0-50 mV, 0-5 V
and 0-10 V.
• 24 Vdc power supply for remote transmitter excitation
• Memory for maximum and minimum values.
• Hold and peak hold functions.
• Digital Input;
• Increasing or decreasing display;
• Process Variable (PV) retransmission in 0-20 mA or 4-20 mA
(optional).
• RS485 MODBUS RTU serial communication (optional).
• 3rd and 4th alarm relays (optional).
PROCESS VARIABLE INPUT - PV
The process variable (PV) input type is configured through the frontal
keypad according to the codes shown in Table 1 (refer to INPUT
TYPE parameter "
").
All input types are factory calibrated and no additional calibration is
required.
