The 1738-IB8M8 input module has been designed and produced by Allen-Bradley/Rockwell Automation and it is a high-quality input module from the Allen-Bradley ArmorPoint I/O module series. This input module, like many of the other ArmorPoint I/O modules, has an enclosure with an IP 67 environmental protection rating and it has M8 types of connectors. The 1738-IB8M8 module has 8 total inputs that are available in 1 group of 8. Also, it should be mentioned that all 8 inputs are non-isolated and sinking inputs. The 1738-IB8M8 module has a specified nominal input voltage rating of 24 Volts DC. The maximum off-state input voltage rating of the module is 5 Volts DC while the maximum off-state input current rating is 1.5 milliamps. In addition to that, the nominal on-state input current rating of the 1738-IB8M8  module is 4 milliamps at 24 Volts DC.

The Allen-Bradley/Rockwell Automation 1738-IB8M8 ArmorPoint I/O series digital input module has multiple LED indicators and it is delivered with a compatible base for easy mounting. The module has an input impedance rating of 3.6 to 4.7 Ohms and an input delay time between the off and on states of 0.5 milliseconds for the hardware. The  1738-IB8M8 digital input module has a single key switch position and a maximum PointBus current rating of 75 milliamps at 5 Volts DC. The maximum thermal dissipation rating of this module is 5.5 BTU per hour at the maximum input voltage rating. In addition to that, the maximum power dissipation rating of the 1738-IB8M8 module is 1.6 Watts at the maximum input voltage rating. The module carries standard industrial certifications like the CE, C-Tick, and c-UL-us certifications. It also meets the requirements for immunity and emissions ratings according to all relevant industrial standards.
