Full preventative maintenance service. Technical support from our in-house engineers. Find out more about our repair service. Want to book a repair? A combination of four thermocouple sensors or mV analogue sensors and can be used at any one time. The AB NT4 features a removable terminal connection block which enables faulty modules to be easily interchanged. There are also two, cold junction compensations CJC sensors to compensate for offset voltages introduced into the input signal as a result of the cold junction.
Configuration of the module is done via the user program as there are no DIP switches. The thermocouple module is powered through the SLC Power Supply, which is positioned on the left hand side of the rack housing.

The NT4 thermocouple input module can support 1 to 4 millivolt or thermocouple analog sensors with its 4 inputs. This input module can be installed in both modular and fixed SLC chassis. The fixed SLC chassis can support up to 2 thermocouple input modules at a time.
To determine whether a given modular chassis can support the NT4 module, calculate the total load that the chassis power supply will have to support with the thermocouple module and all the other devices that it is intended to host.
What is Refurbished? It draws a backplane current of 60 mA and 40 mA at 5 and 24 Volts respectively. The NT4 features a filter frequency of 10 to Hertz and has a step response time of 50 milliseconds at 60 Hertz.
The NT4 has an auto calibration feature which calibrates the thermocouple module on every channel change or when a channel is enabled. The overall module update time is dependent on the number of enabled channels and the CJC update duration.
Platinum, nickel, iron-nickel and copper RTDs can be interfaced with this module. It has a 0. When handling the NT4 make sure to have proper mechanisms in place to take care of electrostatic discharges.
This may include wearing a standardized grounding wrist strap and avoiding the backplane connector pins by handling the NT4 module from the front. The NT4 has a channel sampling time per channel of 12 milliseconds at Hertz, 50 milliseconds at 60 Hertz, 60 milliseconds at 50 Hertz, and milliseconds at 10 Hertz.
The module also has a CJC update time of 14 milliseconds and is configured by entering the feeding values bits into output words 0 to 3 on channels 0 to 3 respectively.

Is this a thermocouple that you are using as you temperature probe? Sound to me like you are using a RTD probe, is that right? Im using a PT thermoresistor , so it isnt like termopar that has types.. PT is a "RTD" not a thermistor or a thermocouple.
Is it possible I use a PT transmitter and send a analog data mA?
