Description

The Allen-Bradley 1756-IB32 is a ControlLogix 32-point digital input module designed for industrial automation applications. Operating within a voltage range of 10 to 31.2 VDC, it features 32 inputs organized into two groups of 16 points each. This module is mounted on a ControlLogix chassis using a removable terminal block housing, such as the 1756-TBCH or 1756-TBS6H. It occupies a single slot in the chassis and has an open-style enclosure. The 1756-IB32 has a nominal input voltage of 24 VDC and a voltage category of 12/24 VDC sink. It draws 120 mA at 5.1 V and 2 mA at 24 V, with a total backplane power rating of 0.66 W. The maximum power dissipation is 6.2 W at 60°C, and the thermal dissipation is 21.1 BTU/hr at the same temperature. The module has a maximum inrush current rating of 250 mA, which decays to less than 37% in 22 milliseconds without activation. In an off-state, its maximum current is 2.27 mA, and its maximum voltage is 5 V. The input delay time for the off-to-on and on-to-off processes differ. For the off-to-on process, there is a hardware delay of up to 380 microseconds plus a user-configurable filter time of either 0, 1, or 2 milliseconds. The on-to-off delay time includes the hardware delay time of up to 420 microseconds plus the user-configurable filter time of either 0, 1, 2, 9, or 18 milliseconds. This module is suitable for applications requiring reliable digital input processing in industrial environments.
