Introduction:

The 1756-IR12 analog input module features 12 analog non-isolated channels and enables 3-wire RTD connections. The module has a status LED display with 24-bit resolution. The input/output ranges that the module offers are as follows: Ohms ranges from 1 to 500, 2 to 1000, 4 to 2000, and 8 to 4000. The 1756-IR12 module draws 200 milliampers at 5.1 volts and 70 milliamperes at 24 volts in terms of current. As a general-purpose I/O device, the 1756-IR12 ControlLogix analog input module has 12 channels in the 3-wire RTD mode. The component is a part of the Bulletin 1756 product line and is manufactured by Allen-Bradley/Rockwell Automation. The input ranges of the module are 1 to 500, 2 to 1000, 4 to 2000, and 8 to 4000 Ohms, with a resolution of 24 bits.

With its capacity to automatically select the last used range-sensor configuration, the 1756-IR12 module offers several input ranges for a variety of sensor types. Included in the family of products that includes the Bulletin 1756/ControlLogix, this unit’s specs are designed to accommodate a variety of industrial applications. This part has a maximum power dissipation of 2.7 Watts and an hourly thermal dissipation of 9.2 BTU. The module has a channel bandwidth that depends on the notch filter setup and overvoltage protection of up to +/- 30 Volts DC. The constant insolation voltage of the 1756-IR12 input module is 250 volts. Furthermore, the device is chassis-mountable and operates within a temperature range of 0 to 60 degrees Celsius (32 to 140 degrees Fahrenheit).
