Allen Bradley 1756-IA32 32-Point AC Input Module

About1756-IA32

TheAllen-Bradley 1756-IA32is aControlLogix Digital I/O Module.

Thecontinuous isolation voltage of this module is 250 V. Its voltage category is 120 V AC and 50/60 Hz, same with its input voltage. The module's current draw at 24 V is 2mA and 165 mA at 5.1 V. The operating voltage ranges from 74 to 132 V AC and 47 to 63 Hz. 0.9 W is the 1756-IA32 module's total backplane power and the maximum inrush current is 390 mA. Input delay times, from screw to backplane, are present in this module; from 'off' to 'on', hardware delay is 1.5 ms nominally or 10 ms maximum plus user-selectable filter time (1 ms or 2 ms), while from 'on' to 'off', the hardware delay is 1 ms nominally or 8 ms maximum plus user-selectable filter time (9 ms or 18 ms). The maximum power dissipation is 6.1 W at 60 Degrees Celsius and thermal dissipation is 20.8 BTU/hour. On an off-state, the maximum voltage is 20 V and the maximum current is 2.5 mA. On the other hand, the on state's current ranges from a minimum of 5 mA at 74 V AC to a maximum of 15 mA at 132 V AC.
