1734-IE2C Allen‑Bradley input module
Product Dimensions：
Product Description
The Allen-Bradley is a basic DC input module designed for use in PLC-5 systems. It provides 16 points of DC input, allowing the controller to interface with field devices such as switches, pushbuttons, and sensors that output a DC signal. The module is part of the 1771 I/O series and is commonly used in industrial automation systems where reliable and cost-effective digital input is required.
