【英文介绍】

The Allen-Bradley 1756-IA32 is a ControlLogix digital I/O module.

The AC input module has a display where the user can check their input and communication status, as well as the health of the module. This particular module has 32 inputs available, with 16 points available in each group. The removable terminal housing or RTB compatible with 1756-IA32 are the 1756-TBCH and 1756-TBS6H.

The module has a continuous isolation voltage of 250 V. Its voltage classes are 120 V AC and 50/60 Hz, the same as its input voltage. The current consumption of the module is 2mA at 24 V and 165 mA at 5.1 V. Operating voltages range from 74 to 132 V AC and 47 to 63 Hz, with 0.9 W being the total backplane power of the 1756-IA32 module and a maximum inrush current of 390 mA. The input delay time from switch to power on, from switch to power on, the hardware delay nominal value of the module is 1.5 ms or a maximum of 10 ms, plus the user's choice of filtering time (1 ms or 2 ms), while from on to off, the hardware delay nominal value is 1 ms, the maximum value is 8 ms, and the input delay time is 1 ms. Plus a user selectable filtering time (9 ms or 18 ms). The maximum power consumption at 60 degrees Celsius is 6.1 W and the heat dissipation is 20.8 BTU/ hour. In the off state, the maximum voltage is 20 V and the maximum current is 2.5 mA. On the other hand, the current in the on-state ranges from a minimum of 5 mA at 74 V AC to a maximum of 15 mA at 132 V AC. The Allen-Bradley 1756-IA32 is a ControlLogix AC input module designed primarily to connect input or signal devices, providing AC input signals in the 74-132VAC range.

The module is a high-density input module with thirty-two (32) input channels divided into two (2) groups of sixteen (16) channels. The module has group to group isolation, which allows the module to function even if the group fails. In addition, it has an isolation feature for input to the backplane, however, it has no isolation between input channels.

The 1756-IA32 is part of the ControlLogix Programmable Automation Controller (PAC) product family. Each channel of the input module has a fixed hardware delay, such as 1.5 ms delay in the OFF to ON conversion and 1 ms delay in the ON to OFF conversion. User-configurable latency can also be set by filtering time options, including 1 ms or 2 ms OFF to ON conversion and 9 ms or 18 ms ON to OFF conversion.

To terminate 1756-IA32 input signals, a detachable terminal (RTB) module is required. Compatible RTB modules include 1756-TBCH (cage clamp terminal) and 1756-TBSH (spring clamp terminal).

The module has a current consumption of 165 mA at 5.1V, 2 mA at 24VDC, a backplane power consumption of 0.9 W, a power consumption of 6.1 W at 60 degrees Celsius, and a heat dissipation of 20.8 BTU/hr.
