The Allen-Bradley 1771-IXE is a PLC 5 Analog Input Module. It is a Thermocouple/Millivolt Input Module. This module utilizes Block Transfer Read and Write (BTR) and (BTW) instructions to transfer input data words from its memory to the PLC processor. The 1771-IXE requires a single-slot for installation in a 1771 I/O chassis and needs no external power supply. The 1771-IXE module has 8 floating differential inputs for thermocouple or millivolt input ranges which includes types E, J, K, T, R, and S thermocouples and +/-100 millivolts. Either 8 inputs are allowed of the same type or 4 each of 2 different types. The 1771-IXE includes cold junction compensation with a range of 0 to 60 degrees Celsius and +/-0.5 degree Celsius accuracy. It has a selectable temperature scale of Celsius or Fahrenheit with a temperature resolution of 1 degree Celsius or 1 degree Fahrenheit and a millivolt resolution of 10 µV. The Allen-Bradley 1771-IXE requires a backplane current load of 750mA at 5V and has a channel update time of 50 milliseconds per 8 channels. Its wiring is connected to the 1771-WI field wiring arm eliminating the need for disconnecting the wires when replacing the module. The 1771-IXE has a maximum power dissipation of 4.25 Watts and maximum thermal dissipation of 14.5 BTU/hour. Keying bands must be put between pins 20 to 22 and pins 24 to 26 which accept only this module. The 1771-IXE module has high and low-temperature alarms that are selectable by the user. It contains a green RUN and a red FLT indicator on the front panel for power and fault status. During power-up, it performs self-diagnostics and reports its status. It provides open-circuit detection in case thermocouple fails. The 1771-IXE automatically calibrates offset and gain for each channel, eliminating the need of potentiometers.
The Allen-Bradley 1771-IXE is an analog input module with Eight (8) Thermocouple and millivolt inputs channels. This module is compatible for installation with any PLC5 chassis. This module may be configured for Celsius and Fahrenheit scale.
This module is a single slot module that directly install to the 1771 chassis slot. It may be installed to any open slot provided that the power supply is adequately sized to provide backplane power to the module. This Thermocouple / millivolt input module support Thermocouple Type E, J, K, T, R and S while supported millivolt value is +/- 100mV. This module is provided with a Cold Junction Compensation.
This module is compatible for use in measurement ranges such as -270 to 1000 Deg. Celsius, -210 to 1200 Deg. Celsius, -270 to 1380 Deg. Celsius, -50 to 1780 Deg. Celsius, -270 to 400 Deg. Celsius.
This module is specifically compatible for use in Temperature applications as Thermocouple sensors are Temperature measuring devices. Additionally, the resistance input compatibility may be used to measure displacement of devices, typically in factory automation applications.
This module has Temperature resolution of 1 Deg. Celsius or 1 Deg. Fahrenheit. It is also provided with a user defined high and low temperature alarms which may be linked to Human Machin Interface (HMI) or Supervisory Control and Data Acquisition (SCADA) systems for monitoring.
This module converts the received millivolt signal to binary or BCD format. It has Thermocouple linearization of IPTS-68 Standard, NBS-MN-125.

What type of input does this module have?
The 1771-IXE has a thermocouple millivolt input.
The Allen-Bradley 1771-IXE is a PLC5 isolated analog input module that is compatible for installation with any 1771 I/O chassis. This module has Eight (8) analog input channels compatible for Thermocouple sensors such as Type E, J, K, T, R and S and resistance of +/- 100 mV.This module is used with Block transfer instructions such as BTW and BTR for sending and receiving analog data and instructions.
The Allen-Bradley 1771-IXE is Thermocouple / millivolt input module. This module is specifically designed for use in Temperature and displacement measurement. Standard analog input modules such as the 1771-IFE may also be used however, this module requires a transmitter that generate voltage or current signal. With the use of 1771-IXE, the module may directly connect to the instruments itself, without the need of transmitters.
