N1040i Indicator
UNIVERSAL INDICATOR – INSTRUCTIONS MANUAL – V2.0x A
PRESENTATION
N1040i is a quite versatile process indicator. With a wide list of input
types - thermocouples, thermo-resistance, voltage and current – the
N1040i is capable of measuring the majority of the variables and
sensors encountered in industrial processes.
The configuration can be performed directly on the indicator or through
the USB interface. The
NConfig
software (free) is the configuration
management tool. Connected to the USB of a
Windows
computer, the
indicator is recognized as a serial communications port (COM) running
with a Modbus RTU protocol.
Through the USB interface, even if disconnected from the power
supply, the configuration performed in a piece of equipment can be can
be saved in a file and repeated in other pieces of equipment that
require the same configuration.
It also features various alarm functions, display offset, configuration
with password protection, serial communication, indication in degrees
Celsius (°C) or Fahrenheit (°F), among others.

ALARMS
The 1040i can have none, one or two alarms. Each alarm present is
associated to one output with the same name (ALARM1 and ALARM2).
OUTPUT
ALARM1
- Relay SPDT. Available in terminals 10, 11 and
12 of the indicator.
OUTPUT
ALARM2
- Relay SPST-NA. Available in terminals 13 and
14 of the indicator.
The alarms can assume the functions described on
Table 02
.
