AB 1756-IB32 ControlLogix 32 Pt 12/24V DC D/I Module

Technical Specifications for 1756-IB32

About  1756-IB32

The Allen-Bradley 1756-IB32 is a ControlLogix digital I/O module. Part of the ControlLogix system, this input module has 32 inputs available in 2 groups, with 16 points in each group. It is mounted to a ControlLogix chassis by using the required removable terminal block housing, or RTB, such as either the Allen-Bradley 1756-TBCH or 1756-TBS6H. This module, occupies a single slot of the ControlLogix Chassis and supplied with an open enclosure type. The 1756-IB32 module has an operating voltage range of 10 to 31.2 Volts DC and a nominal input voltage of 24 Volts DC. It has a voltage category of 12/24 Volts DC sink, a current draw of 120 mA at 5.1 Volts and 2 mA at 24 Volts, and a total backplane power rating of 0.66 W. The maximum power dissipation is 6.2 W at 60 degrees Celsius, while the thermal dissipation is 21.1 BTU/hour, also at 60 degrees Celsius.

The Allen-Bradley 1756-IB32 ControlLogix digital I/O module also 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 Volts. 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.

The Allen-Bradley 1756-IB32 is a High-Density Discrete input module that belongs to the ControlLogix product family of Programmable Automation Controllers (PAC). This module features Thirty-Two (32) input channels, grouped in Two (2) with Sixteen (16) channels each group.
