AB 1756IA32 Ser. A Control Logic Input Module AC Input 32 PT

About 1756-IA32

The AB 1756-IA32 is a ControlLogix Digital I/O Module.

This AC input module has a display where users can check its input and communication status, as well as the module health. It can be connected to a ControlLogix chassis and is configurable using the RSLogix 5000 software, where users can change the settings for the input filter times and change of state. This particular module has 32 inputs available, with 16 points available in each group. The removable terminal block housings or RTB, compatible with the 1756-IA32 are 1756-TBCH and 1756-TBS6H.

The continuous 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.
