Allen-Bradley 1734-IE2C 2-Channel Current Input Module

The Allen-Bradley 1734-IE2C is a two-channel analog current input module for POINT I/O that accepts 0–21 mA signals and provides 16-bit measurements to the controller. Each channel, labeled In 0 and In 1, uses a dedicated input terminal with a common reference and chassis ground on the card, making it suitable for connecting two independent 4–20 mA loops from field devices such as pressure transducers, flow meters, or level sensors. The module is powered from the POINT I/O 24 V DC power bus, with 24 V supplied internally across the backplane, enabling field devices to share a single supply. The 1734-IE2C captures current input with two channels and converts it to a high-resolution digital value across a 0–21 mA range, with an update rate that is configurable to control how often each channel is scanned. Typical use cases include industrial automation and process control where precise current-loop signals must be monitored remotely, and the module integrates seamlessly with Rockwell Automation's POINT I/O ecosystem for EtherNet/IP or other supported networks.
