The 1771-IFMS fast millivolt input module by Allen-Bradley has about 8 differential inputs via intrinsic safe connections. The 1771-IFMS input module is designed by Allen-Bradley to handle data in various formats including the +/- 32,767 binary formats or in the +/- 9999 BDC format. When connected to any of the Allen-Bradley chassis in the 1771 I/O chassis series, the 1771-IFMS input module can update itself within 14.5ms and its resolution is recorded as being 12 bits. The range of the nominal input volts for the 1771-IFMS fast millivolt input module is 0-50 millivolts while the backplane current that it needs is recorded as being 750mA.


For connectivity, the Allen-Bradley 1771-IFMS fast millivolt input module does not require any external power supply sources, although it is packaged with an Allen-Bradley 1771-WG wiring arm from the Allen-Bradley factory. The wiring arm is useful while disconnecting the 1771-IFMS input module from the processor because it can disconnect the input module without interrupting or disconnecting the whole wiring system. In any case, the 1771-IFMS module has a conformal coating that provides the system with the necessary protection from humidity and condensation. The 1771-IFMS module is rack mountable and its normal AC signal delay is 24ms when it is powered off. The normal DC signal delay when 1771-IFMS module is powered off is 20ms. Other additional features of the Allen-Bradley 1771-IFMS fast millivolt input module include its selectable real-time sampling, its digital filtering, and its ability to scale to different engineering units.
