Allen-Bradley 1734-IA2 is a two-channel digital input module for the POINT I/O system that accepts 120 VAC inputs to monitor two independent digital signals. In use, it reports input status to the scanner as a single 1-byte data word, with each channel mapped to a dedicated bit in that byte. The module operates on 60 Hz AC input and draws on-state current per channel that varies with input voltage, specified as 4.0 mA @ 65 V AC up to 8.5 mA @ 132 V AC, and 6.2 mA @ 159 V AC up to 10.2 mA @ 264 V AC. This makes it suitable for connecting simple field devices such as switches and sensors in industrial automation networks that employ POINT I/O for remote I/O expansion.
