Product Technical Profile – ABB BTDR‑01C (3AUA0000094845)
1) Brand and Series Overview
Brand: ABB
Series: BTDR Industrial Drive & Automation Interface Modules
The BTDR series comprises a range of interface and signal processing modules engineered for industrial automation, drive communication, motion control, and discrete monitoring tasks. These modules serve as bridges between field devices (sensors, switches, encoders), motor drives, programmable logic controllers (PLCs), and higher‑level automation systems. They are designed for robust performance in harsh environments, facilitating reliable data transmission and effective control actions.
The BTDR‑01C is a single‑channel drive interface and signal conditioning module within this series, tailored for discrete inputs, status monitoring, and drive‑level communication integration.
2) Product Overview
The ABB BTDR‑01C (3AUA0000094845) is an industrial drive interface and signal conditioning module used for collecting, processing, and transmitting status and control signals in automation systems. The module supports digital input signals from field sensors and switches, conditions these signals to prevent noise‑related errors, and then communicates the clean signals to drives or PLCs.
BTDR‑01C operates on a 24 V DC control supply and features galvanically isolated input circuits to protect control electronics from electrical interference. Its compact design and DIN rail mounting mechanism support neat, space‑efficient installation in control cabinets.
This product is suitable for a wide range of automation tasks where high‑integrity signal conditioning and interface reliability are crucial, particularly in motor control panels, conveyor automation, and industrial safety monitoring systems.

4) Product Description
The BTDR‑01C module is designed to serve as a reliable interface for digital signals between field devices and control systems in industrial automation environments. Its purpose is to ensure clean, noise‑free digital signal transmission, particularly where long cable runs or electromagnetic interference (EMI) from motors and power equipment might otherwise corrupt data.
By providing galvanic isolation, BTDR‑01C protects control electronics from transient voltage spikes and common electrical noise sources. This contributes to improved system stability and reduced downtime due to false triggers or signal distortion. The module’s compact DIN rail form factor simplifies installation and reduces cabinet footprint usage.
BTDR‑01C typically connects to push‑buttons, limit switches, proximity sensors, and drive enable/disable circuits, processing these signals before sending robust digital status information to automation controllers.
