What is the 1492 AI8FM5 Module?

The 1492 AI8FM5 module is an 8-channel analog input module designed for use with Allen-Bradley’s ControlLogix programmable automation controllers. The module is used to interface with a variety of analog devices, including temperature sensors, pressure sensors, and flow meters. The module has a 12-bit resolution and can measure signals with a range of ±10 volts or ±20 mA.

The module is designed to be easy to use, with a removable terminal block for easy wiring and configuration. It also has built-in diagnostics to help troubleshoot any problems that may arise.

Wiring the 1492 AI8FM5 Module

Wiring the 1492 AI8FM5 module requires a basic understanding of electrical wiring and the ControlLogix system. The module is typically mounted in a ControlLogix rack and is wired to the input devices using a terminal block.

Power Wiring

The first step in wiring the 1492 AI8FM5 module is to connect power to the module. The module requires a DC power supply with a voltage range of 18-32 volts. The power supply should be connected to the module’s power input terminal, which is labeled “+VDC” and “-VDC”. Make sure to observe proper polarity when connecting the power supply.

Signal Wiring

After connecting the power, the next step is to connect the input signals to the module. The input signals are connected to the module’s channel input terminals, which are labeled “CHx+” and “CHx-“. The “CHx+” terminal is connected to the positive signal wire, while the “CHx-” terminal is connected to the negative signal wire. Make sure to observe proper polarity when connecting the signal wires.

The module’s input channels are numbered 0-7, with channel 0 being the first channel. The wiring for each channel should be identical, with the signal wires connected to the corresponding channel input terminals.

Grounding

Grounding is an essential part of any electrical system, and the 1492 AI8FM5 module is no exception. The module’s ground terminal should be connected to a suitable grounding point. A good grounding point is the ControlLogix system’s ground reference, which is typically located on the rack’s power supply.
