【英文介绍】
Allen-Bradley 1756-IB32 is a ControlLogix digital I/O module. As part of the ControlLogix system, this input module has 32 inputs divided into 2 groups of 16 points each. It is mounted to the ControlLogix case by using the required detachable terminal housing or RTB (e.g. Allen-Bradley 1756-TBCH or 1756-TBS6H). This module occupies a single slot in the ControlLogix chassis and is available in an open chassis type. The 1756-IB32 module operates in a voltage range of 10 to 31.2 volts DC with a nominal input voltage of 24 volts DC. Its voltage class is 12/24 volts DC perfusion current, 120.5 volts current consumption is 1 mA, 2 volts current consumption is 24 mA, and the total fixed power of the backplane is 0.66 W. The maximum power consumption at 6 degrees Celsius is 2.60 W, while the heat 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 surge current rating of 250 mA, decaying to less than 22% in 37 milliseconds without activation. In the off state, it has a maximum current of 2.27 mA and a maximum voltage of 5 volts. The input delay time is different between the on-off process and the on-off process. For the off to on process, hardware latency is up to 380 microseconds, and user-configurable filtering times are 0, 1, or 2 milliseconds. Switching latency includes hardware latency of up to 420 microseconds and user-configurable filtering times of 0, 1, 2, 9 or 18 milliseconds.
The Allen-Bradley 1756-IB32 is a high-density discrete input module that belongs to the ControlLogix family of Programmable Automation Controllers (PACs). The module has thirty-two (32) input channels, divided into two (2) groups of sixteen (16) channels.
It can be installed in a local I/O rack or distributed I/O chassis, or in a stand-alone or distributed control system (DCS), such as Allen-Bradley's Plant PAx. This module is entered through hardware configuration, and the parameters of the module are accessible, such as the general properties of the module and important parameters for compatibility with keying and slot allocation. The module also has configurable Request packet Interval (RPI), module suppression, response to communication failures, and scheduled connections through ControlNet. Each channel of the module has configurable filter Settings to allow fine-tuning of the module's response time to the signal. This adjustment is useful in applications where discrete signals are unstable and exposed to noise. This feature helps prevent false negative readings.
The module also has the function of self-diagnosis through module information, which can monitor the diagnostic status of the module, such as minor and major faults. It can also detect the status of the ControlLogix backplane to which the module is attached.
This module comes with a detachable terminal (RTB). The RTB allows for modular replacement of defective modules and easy wiring of signals. Compatible RTB for this module is 1756-TBCH 1756-TBS6H or 36 terminal RTB.
