Part Number/Catalog Number 1756-IF16K Model
Series ControlLogix
Module Type Analog input module
The Allen-Bradley 1756-IF16K module is an analog I/O module with conformal coating for the Allen-Bradley ControlLogix 5580 controller. There are 16 single-ended inputs on the 1756-IF16K module, of which 8 can be used as differential inputs and 4 as high-speed differential inputs. The module can be used for voltage and current input. Supported input ranges are ±10 volts, 0 to 10 volts, 0 to 5 volts, and 0 to 20 MA. Input resolutions are 320 microvolts/count (15-bit + bipolar symbol) (±10.25 volts), 160 microvolts/count (16-bit) (0 to 10.25 volts), 80 microvolts/count (16 bits) (0 to 5.125 volts), and 0 to 20.5 mA (0 to 20.5 Ma) is 0.32 microamps/count (16 bits).
The module current consumption of the 1756-IF16K module is 65 MA at 24 volts and 150 MA at 5.1 volts. Total power consumption of the backplane is 2.33 Watts. The module has an input voltage range of -10 to 10 volts and an input current range of 4 to 20 mA. Power consumption less than 100 VA. The module has a power consumption of 2.3 watts for voltage input and 3.9 watts for current input. The 1756-IF16K module has a heat dissipation of 7.8 BTU per hour for voltage input and 13.3 BTU per hour for current input. The input impedance of the voltage input is greater than 10 megohm, and the input impedance of the current input is 249 ohms. The conversion method used on the 1756-IF16K module is the sigma-delta method. The 1756-IF16K module complies with the T4 ATEX temperature specification.
