About

The 1762-IT4 is an Allen-Bradley MicroLogix 1200 Thermocouple/mV Input Module. This thermocouple/mV module is used to digitally review and store converted thermocouple and/or millivolt analog date from up to 4 thermocouple or millivolt analog sensors. This thermocouple/mV module features a terminal block with a cold junction compensation sensor. Each input channel is individually configurable through software for specific input devices, data format, and filter frequency, and provides open-circuit, over-range, and under-range detection and indication.  Communicates to the controller through the bus interface. The modules also receive 5 and 24 Volt DC power through the bus interface. This product is approved for installation within the European Union and EEA regions. All 1762 Thermocouple/mV modules receive its power from the 1762 expansion I/O bus. The power supply distance rating of this 1762 Thermocouple/mV module is 6. The rated working voltage of 1762-IT4 is 30 Volts AC. The input filtering of a 1762 Thermocouple module is a programmable notch filter.

The 1762-IT4 has 4 inputs channels plus 1 CJC sensor. The 1762-IT4 has a resolution of 15 bits plus sign. Installation should be in an industrial enclosure to reduce the effects of electrical interference. Analog inputs are extremely susceptible to electrical noise. Electrical noise coupled with the analog inputs will reduce the accuracy of the module. Allow 50.8 millimeters (2 inches) of space on all sides for proper ventilation. The dimensions of this module are around 3.54 x 3.43 x 1.58 inches including mounting tabs of 4.33 inches and has a weight 0.53 pounds. The operating temperature for this module should be between 32 degrees to 131 degrees Fahrenheit.
