SAFETY ALERTS 

The symbols below are used on the equipment and throughout this 
document  to  draw  the  user’s  attention  to  important  operational  and 
safety information. 

 

 

CAUTION: 

Read the manual thoroughly 

before installing and operating the 

equipment.  

CAUTION OR DANGER:  

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. 

INTRODUCTION 

The N1200 is an extraordinarily versatile process controller. It holds 
in  one  single  instrument  all  the  main  features  needed  for  the  vast 
majority of industrial processes. It accepts in a single model virtually 
all  the  sensors  and  signals  used  in  the  industry  and  provides  the 
main output types required for the operation of diverse processes.  
The  configuration  can  be  performed  directly  on  the  controller  or 
through  the  USB  interface.  The 

NConfig

  software  (free)  is  the 

configuration management tool. Connected to the USB of a Windows 
computer,  the  controller  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 is important that the users read carefully this manual before using 
the  controller.  Verify  if  the  release  of  this  manual  matches  the 
instrument version (the firmware version is shown when the controller 
is energized). The N1200 main characteristics are: 

 

Multi-sensor universal input; 

 

Protection for open sensor in any condition; 

 

Relay,  4-20  mA  and  logic  pulse  control  outputs  all  available  in 

the standard model; 

 

Self-tuning of PID parameters; 

 

Automatic / Manual function with “

bumpless”  

transfer; 

 

  Four modes of independents alarms, with functions of minimum, 

  maximum, differential (deviation), open sensor and event; 

 

Timer functions that can be associated to the alarms; 

 

Retransmission of PV or SP in 0-20 mA or 4-20 mA; 

 

Input for remote 

setpoint

 

Digital input with 5 functions; 

 

Programmable 

soft-start

 

20  setpoint  profile  programs  with  9  segments  each,  with  the 

ability to be linked together for a total of 180 segments; 

 

Password for parameters protection; 

 

Universal power supply.

CONFIGURATION OF OUTPUTS, ALARMS AND DIGITAL INPUTS  

The controller input and output channels (I / O) can assume multiple 
functions:  control  output,  digital  input,  digital  output,  alarm  output, 
retransmission of PV and SP. These channels are identified as 

I / O 

1, I / O 2, I / O 3, I / O 4 

and

 I / O 5

The basic controller model comes loaded with the following features: 
 

I / O 1-  output to Relay SPST-NA; 

 

I / O 2-  output to Relay SPST-NA; 
I / O 5-  current output, digital output, digital input; 

Optionally

, other features can  be added, as shown  under the item 

“Identification” in this manual: 

3R

I / O3 with output to SPDT relay; 

DIO

:   I / O3 and I / O4 as digital input and output channels; 

HBD

:   Heater break detect; 

485

:  Serial Communication; 

The function to be used in each channel of I/O is defined by the user 
in accordance with the options shown in the
