Allen Bradley 1756-IF16 ControlLogix 16 Point A/I Module Brand new

Allen Bradley 1756-IF16 ControlLogix 16 Point A/I Module

The Allen-Bradley 1756-IF16 is a ControlLogix module that features Sixteen (16) single ended or Eight (8) Differential or Four (4) differential high-speed analog input channels. This module supports input signal ranges of ±10V, 0-10V, 0-5V and 0-20 mA with resolution of 320 µV/count (15 bits + sign bipolar) @ ±10.25V; 160 µV/count (16 bits) @ 0-10.25V; 80 µV/count (16 bits) @ 0-5.125V and 0.32 µA/count (16 bits) @ 0-20.5 mA. This module is used with 1756-TBCH or 1756-TBS6H Removable Terminal Block (RTB).With single-ended wiring, the module becomes a Sixteen (16) channel analog input module. Similarly, the module is reduced to an Eight (8) channel analog input module when used with differential wiring. Furthermore, the module becomes a Four (4) channel analog input module when the module is wired as high-speed differential wiring.

Description:

The Allen-Bradley 1756-IF16 is a ControlLogix analog input module. This module accepts current and voltage signals such as ±10V, 0-10V, 0-5V and 0-20 mA. This module supports Three (3) types of signal wiring configuration such as single-ended, differential and high-speed differential wiring. Among the supported wiring configurations, single-ended wiring is the most sensitive to noises and must be used with signals having a common ground. For increased noise susceptibility, differential wiring method is used while high-speed differential wiring is used in systems that require fast data updates, relative to the input signals.

The 1756-IF16 individual resolutions are 320 µV/count (15 bits + sign bipolar) @ ±10.25V input range; 160 µV/count (16 bits) @ 0-10.25V input range; 80 µV/count (16 bits) @ 0-5.125V input range and 0.32 µA/count (16 bits) @ 0-20.5 mA. This module has scan time that varies such as16-488 ms for single-ended; 8-244 ms with differential wiring and 5-122 ms with high-speed differential wiring. It has a built-in analog-to-digital converter circuitry using the Sigma-Delta method. Converted data is stored following integer mode (left justified, 2 s complement) IEEE 32-bit floating point data format. This module has a calibrated accuracy of better than 0.05% of range for Voltage input and 0.15% of range for Current input.

The current draw of this module at 5.1 Volts is 150 mA, or is 65 mA at 24 Volts. The voltage and current ratings of the backplane are 5.1 Volts DC, 150 mA at maximum, and 24 Volts DC 65 mA at maximum. The input current range is from 4 to 20 mA and the input voltage range is from -10 to 10 Volts and limited to 100VA. The Voltage power dissipation is around 2.3 Watts and the current power dissipation is 3.9 Watts. The thermal dissipation for the voltage is 7.84 BTU/hour and 13.3 BTU/hour for current. It also has a maximum overvoltage protection of 30 Volts DC (voltage) and 8 Volts DC (current).
