FAQ for 1756-IF8IHK
The Allen-Bradley 1756-IF8IHK ControlLogix I/O Module is an 8-channel isolated module with a dedicated Highway Addressable Remote Transducer (HART) modem for each channel. This module takes advantage of the New or Existing HART Device Strength. The HART inputs and outputs provide the process automation system with complete analog capability. The benefits of the HART protocol in I/O modules can be used locally or remotely. The HART ControlLogix module maximizes the performance of your system by combining real-time HART and standard analog data at a fraction of the cost. This module can simplify commissioning, operation, and maintenance with increased insight into device status. You can use digital data as the basis for your asset management systems. In addition, device status and diagnostic codes are available without a handheld device.
The Allen-Bradley 1756-IF8IHK has an input range of 0-20 mA and 4-20 mA. The resolution of this module is from 16-21 bits. The 1756-IF8IHK is compatible with HART 5, 6, 7. Its Module HART Scan Time is around 1 second if all channels are HART-enabled. The Open-Circuit Detection Time of this module is 5s (4-20 mA range only). The Overvoltage Protection of this module is 28.8V DC. This module has Impedance of 250 Ω ±5 Ω. The isolation voltage of this module is 250V AC RMS working voltage. The calibrated accuracy at 77 °F with HART Disabled is 0.15% - 1.5% of full scale and depends on the selected filter.
