A-B 1756-IB32

The A-B 1756-IB32 module is A ControlLogix series of digital input modules manufactured by Allen-Bradley. It has two sets of 32 input channels, each consisting of 16 channels. Modules operate in a voltage range of 10 to 31.2 volts direct current (VDC) with a nominal input voltage of 24 VDC. In addition, the module has a maximum surge current rating of 250 mA and can decay to less than 37% in 22 milliseconds when unactivated. The A-B 1756-IB32 module can be installed in A local I/O rack, distributed I/O chassis, or integrated into a stand-alone or distributed control system, such as Allen-Bradley’s Plant PAx. The module also provides configurable filter Settings that allow the user to fine-tune the module’s response to the signal 12.
