Allen Bradley 1746-NT8 Ser A Thermocouple mV Input Module SLC 500 1746NT8 (A)
one year warranty
The Allen-Bradley 1746-NT8 is a SLC 500 Thermocouple/mV Analog Input Module. This Thermocouple/mV Analog Input Module has 8 Inputs and a Backplane Current (5 Volts) of 120 milliamps.
The 1746-NT8 SLC 500 Thermocouple/mV Analog Input Module by Allen-Bradley is an 8-channel chassis-installed module which stores thermocouple/mV analog data that has been digitally converted for retrieval by any SLC 500 processors. It has 8 isolated input channels with a backplane rating of 120mA at 5V DC and one of 70mA at 24V DC with an overall backplane power of 2.28W. The 1746-NT8 uses a Delta-Sigma signal conversion method and it has a digital low pass filter with selectable programmable filter frequencies. Its normal mode rejection frequency between the terminals is greater than 100dB at 50-60 Hz and its common mode rejection frequency between inputs and ground is also above 100dB at 50-60 Hz. The 1746-NT8 module automatically calibrates itself from power approximately every 2 minutes after power up. It offers input overvoltage protection at ±30V DC and 600W pulsed for 1ms and provides 12.5V DC circuit isolation tested at 500V DC for 1 minute between inputs and the chassis ground and between the inputs and backplane.
The 1746-NT8 has 9 green LED lights that indicate a channel status and the module’s status. It uses the 1746-RT34 (RTB) removable terminal block for connection to 8 thermocouple or analog input devices, and on the RTB there 1746-NT8The are 2 cold-junction compensation (CJC) sensors with an accuracy of ±1.72°C. The 1746-NT8 has various selectable input types and the module’s overall input impedance is greater than 10 M Ohms. Any input devices connected to it must have an impedance of fewer than 100 Ohms to meet the accuracy level. The 1746-NT8 offers a selectable open-circuit detection with 1 cycle per channel and an overall input stem response time of 400ms. The module has a functional temperature range between 0°C and 60°C at 5-95% humidity without condensation and is UL and CUL-approved.
