3RA2711-1CA00

Description

Overview

The Siemens 3RA2711-1CA00 is a high-performance function module designed for integration with Siemens SIRIUS 3RT20 series contactors. It enables IO-Link communication and supports star-delta (wye-delta) starting methods for motor control. With screw-type terminals and a front snap-on mounting mechanism, this module offers a compact and efficient solution for modern automation systems.

Key Benefit

• Seamless IO-Link Integration: Enables communication capabilities between the contactor and higher-level automation systems, reducing wiring complexity.

• Star-Delta (Wye-Delta) Starting Support: Allows reduced voltage start for larger motors, improving energy efficiency and reducing startup stress on the motor and network.

• Front Snap-On Mounting: Easily mounts onto communication-capable 3RT20 contactors, saving installation time and simplifying mechanical assembly.

• Screw Terminal Connection: Robust and secure screw-type terminal connections for control and auxiliary circuits, ensuring reliable electrical contact.

• Compact & Standardized Design: With a net weight of ~0.235kg and standard module width, the unit is designed for efficient integration into control cabinets and motor control centres.

Key Function & Specification

• Function module for IO-Link communication interface.

• Supports star-delta (wye-delta) starting method of motors for contactor assemblies.

• Designed to snap on front-side onto communication-capable contactors of the SIRIUS 3RT20…-…..-0CC0 series.

• Screw-type terminal connections for auxiliary/control circuits: solid and stranded wires per specification.

• Ambient operating temperature: –25 °C to +60 °C (per typical specification) and IP20 front protection.

• Country of origin: Czech Republic. Net weight approx. 0.235 kg. Commodity code 85371098.

Application

• Ideal for motor control systems where a star-delta starter is required (larger motors) and where IO-Link communication enhances diagnostics and integration.

• Suitable for OEM machines, control panels and industrial automation where space, wiring efficiency and smart connectivity are priorities.

• Retrofitting older motor starters to modern IO-Link capable systems, enabling smarter maintenance and status monitoring.
