TRICONEX 3503EC1 Product Introduction

TRICONEX 3503EC1 is a digital input/output module from Schneider Electric’s Triconex series,designed for high reliability scenarios in industrial automation and process control.It supports redundant architecture and multi protocol communication,making it suitable for safety critical applications.

Core functions

Redundant design

Adopting a Process Redundancy(PR)architecture,it contains two independent channels internally and supports seamless switching to the backup channel in case of a main channel failure,ensuring system continuity.

Some models support Triple Modular Redundancy(TMR),where each input signal is processed in parallel by three independent hardware channels and the impact of a single point of failure is eliminated through a majority voting mechanism.

High density I/O channels

Provide 32 digital input channels(8 channels per group),support current injection/source current input mode,compatible with 24V AC/DC power supply.

The input signal range covers 20-42.5V DC or 10-42.5V AC,and the frequency range includes DC and 47.63Hz AC signals.

Industrial grade reliability

Protection level IP68,supporting waterproof,moisture-proof,and immersion resistance,suitable for harsh environments such as high temperature(-40°C to+70°C),high humidity,and vibration.

Built in overload protection,ripple filtering,and thermal management functions ensure long-term stable operation.

Communication and Integration

Supports industrial protocols such as MODBUS RTU and Profibus,compatible with ControlLogix PLC and 750 series WAGO gateway,achieving seamless integration with upper level control systems.

Provide Ethernet and RS485 interfaces,supporting remote monitoring and data exchange.

Fault diagnosis and self inspection

Real time monitoring of channel status,detecting anomalies such as jamming,short circuit,overload,etc.,triggering alarms and recording fault events.

Support online maintenance,allow hot swapping to replace faulty modules,and reduce system downtime.
