The 1738-IB2M12 from Allen Bradley functions as an input module within the ArmorPoint range. This device includes two non-isolated sinking inputs that operate effectively in a proactive industrial setting. Designed to handle an input voltage spectrum from 10 to 28.8 Volts DC, it maintains a nominal input impedance of 3.6 kiloohms, providing stable signal processing. When in the ON state, the module registers a nominal voltage of 24 Volts DC.

The operational thresholds for current are defined, with a minimum ON-state input current of 2 milliamperes, and it can support a maximum current of 5 milliamperes when engaged. During the OFF state, an input current of up to 1.5 milliamperes is permissible, ensuring that power is efficiently utilized and minimizing unwanted signals.

For connectivity, this input module employs DC Micro connectors, specifically M12 circular connectors, which comply with common industry standards. Additionally, it features a robust protection degree rated at IP67, confirming its suitability for rugged conditions where dust and moisture could pose a concern. The maximum power dissipation at full input voltage is recorded at 0.7 Watts, which showcases the module's efficiency.

The module is capable of managing a maximum PointBus current measuring up to 75 milliamperes at 5 Volts DC. An isolation voltage of 50 Root-Mean-Square indicates its reliability in safeguarding against electrical disturbances, making it fit for various applications in automation and control.
