Product Description:

The 0AC240.9 is an interface converter module manufactured by B & R Automation and supplied within the 0AC Interface Converters series. It is intended to sit on its own base-plate module and provide a pre-wired connection point that routes field signals through terminal blocks to the automation backplane. The unit also houses two block-cell batteries that support local functions requiring backup power. Its layout is suited to compact control assemblies where orderly field termination and battery support are needed in one place.

This module is delivered with a cable that measures 40 cm, allowing short, organized runs between the converter and adjacent rack slots. Field conductors land on a terminal block connector with 5 terminal pins, providing clear screw-clamp connection points without extra adapters. Each installed battery supplies 9 V, and the pair sits in a compartmented holder sized for the block-cell form. The housing is rated IP20, and the electronics remain functional across an operating range of 0 °C to +60 °C. Two terminal blocks are included with the device, matching the module’s pre-wired layout.

The unit includes 2 battery compartments molded into the base plate, and that base plate is already attached, eliminating separate mounting hardware. Its profile occupies a Single Width slot, which helps conserve rack space when multiple interface converters are installed in the same assembly. When powered down, components tolerate storage temperatures from -25 °C to +70 °C, allowing safe transport and storage in typical warehouse conditions. The module mounts in its designated base-plate position, and the internal wiring is factory terminated. The included terminal blocks match the pre-wired connections, which helps keep installation straightforward and keeps field wiring organized.
