Product Description:
The 3IF7E3.9 module is an interface component from the System 2005 Controllers series produced by B&R Automation. Installed on the backplane of a System 2005 PLC, it provides a single PROFINET channel and local wiring points for field signals. That role lets sensors and other devices exchange data with the central processor in distributed automation layouts.
This unit operates in ambient temperatures from 0 °C to 60 °C, allowing reliable use in standard control cabinets near heat-generating equipment. Continuous service is permitted when relative humidity remains below 95 %, which helps the module suit demanding industrial rooms without condensation. The single PROFINET interface counts as 1 network connection for topology planning. With a power demand of only 1.6 W, the card places very little load on the system power budget.
The board draws its logic voltage from a 3.3 VDC supply rail routed through the carrier, so no separate local source is required. Safe storage is specified between -25 °C and 70 °C, which helps protect the electronics during transport and warehousing. Field wiring terminates on a removable block with four conductors, and each position accepts up to 2.5 mm² cable for secure industrial connections.
Wake Industrial offers a 1-year warranty on every purchase. Same-day shipping can be arranged for urgent orders, and quotations remain valid for 30 days to support planning. The chat tool available on the website can be used for questions about fault codes or general specifications before purchase when quick clarification is needed during business hours.
