The Allen Bradley 1492-IFM20D24A-2 is a digital interface module (IFM) optimized for applications that require direct input connections. It is capable of supporting up to 16 input channels while also providing for necessary power connections. This module has a distinctly A Type configuration, focusing on input functionality.

Connection to the Programmable Logic Controller (PLC) is made via a 20-pin male header. Each channel consists of two field terminals—one designated as signal input and the other as a voltage source—allowing for versatile wiring options. It is compatible with wire sizes ranging from #22 to #12 AWG, accommodating a broad spectrum of installation requirements.

The module mounts on standard 35 mm DIN rails, ensuring straightforward integration into control panel setups. It operates within a voltage range of 10 to 30 volts AC/DC, with a nominal operating voltage of 24 volts DC. Each circuit can handle a maximum current of 2 amps, while the entire module can manage up to 12 amps in total reference current across all circuits.

For visual status indicators, red LEDs are provided for each input channel, facilitating quick diagnostics and system monitoring. Additionally, the module has an approximate leakage current of 2 mA, which is primarily utilized to power the LED indicators.
