About 1769-IT6
The catalog number 1769-IT6 is used for an Allen-Bradley/Rockwell Automation compact I/O thermocouple/millivolt input module that has 6 input channels as well as 2 CJC sensors. The module has a maximum bus current draw of 100 milliamps at 5 Volts DC and 40 milliamps at 24 Volts DC. The 1769-IT6 module has an input impedance of less than 10 millivolts and rated working voltage of 30 Volts AC or 30 Volts DC. The unit uses a Delta-Sigma converter, and it has a heat dissipation rating of 1.5 Watts in total. The 1769-IT6 module has a common mode rejection rating of 115 decibels and normal mode rejection ratio of 85 decibels at 50 to 60 Hertz. The open-circuit detection time is typically 7 milliseconds to 2.1 seconds and the module performs automatic calibration at power up.Additionally, the Allen-Bradley 1769-IT6 input module has features like status indicators and channel diagnostics functions. The unit weighs around 276 grams (0.61 pounds) and its dimensions include a height of 118 millimeters (4.65 inches), a width of 87 millimeters (3.43 inches), and a depth of 35 millimeters (1.38 inches). Also, the 1769-IT6 input module has an operating temperature range of 0 to 60 degrees Celsius (32 to 140 degrees Fahrenheit) and a storage temperature range of -40 to 85 degrees Celsius (-40 to 185 degrees Fahrenheit). The 1769-IT6 module can tolerate 30 g of shock for the duration of 11 milliseconds and 40 g of non-operating shock when it is mounted on a panel. The manufacturer recommends using Belden 8761 shielded cable for the millivolts inputs.
The Allen-Bradley 1769-IT6 module is a compact thermocouple and millivolt input module. Different thermocouples with different temperature ranges can be used with the I/O module including the J, K, T, E, R, S, B, N, and C thermocouples. There are 2 types of millivolt input ranges supported by the module, including +/-50 millivolts and +/-100 millivolts. Six RTD inputs and 2 CJC sensors are provided on the 1769-IT6 input module. The configurable input ranges are 0 to 3 kiloohms, 0 to 1 kiloohm, 0 to 500 Ohms, and 0 to 150 Ohms. The bus current draw for the 1769-IT6 input module is 140 milliamps at 5 Volts DC and 30 milliamps at 24 Volts DC. The module input impedance exceeds 10 Megaohms. The cable resistance rating should not exceed 25 Ohms.
The accuracy for the CJC assembly is +/-1.0 degree Celsius. The nonlinearity is +/-0.3%. The open-circuit detection time is 7 milliseconds to 2.1 seconds. The rated overload for input terminals is +/-35 Volts DC continuous. The group to bus isolation voltage is 720 Volts DC. The weight of the 1769-IT6 module is 0.61 pounds. The dimensions of the module are a height of 118 millimeters, a width of 35 millimeters, and a depth of 87 millimeters. The 1769-IT6 input module can be panel mounted or installed on a DIN rail. The module occupies 1 slot. Four external power supplies are compatible with the module, including the 1769-PA2, 1769-PA4, 1769-PB4, and 1769-PB2 power supplies. The power supply distance rating is 8 modules. The recommended terminal screw torque is 6 pounds on an inch. The recommended cables for 2-wire, 3-wire, and 4-wire configurations are the Belden 9501, Belden 9533, or Belden 83503 cables, respectively, or their equivalents.
