Schneider TSX3705028DR1 PLC Configurations Module

Product Overview

The TSX3705028DR1 provides a complete I/O configuration for Modicon PLC systems. You will find this module in conveyor control and batch processing lines. It combines digital inputs, outputs, and power supply in one unit. Furthermore, this module includes relay outputs for direct motor control. Therefore, you do not need separate interface relays for small loads.

Technical Specifications

The table below lists all key parameters for this PLC configuration module.

Status LEDs	One power LED, 16 input LEDs, 12 output LEDs
Mounting	DIN rail (35 mm) with screw lock

The TSX3705028DR1 stores no energy that requires discharge procedures. Therefore, you can work on this module immediately after power removal. Use the 28-pin terminal block for all field wiring connections. Meanwhile, the relay outputs switch AC or DC loads directly.

Installation and Compatibility

You can mount this module on any 35 mm DIN rail. Slide the TSX3705028DR1 onto the rail from the front. Then tighten the bottom screw lock to secure it firmly. Always install a fast-blow fuse on the common output line.

This module works with all TSX Micro PLC bases. It auto-detects the slot position during power-up. The TSX3705028DR1 replaces older TSX37 series I/O modules without software changes.

Environmental and Safety Data

The TSX3705028DR1 operates from 0°C to +55°C. It withstands 2g vibration per IEC 60068-2-6 testing. The circuit board has no conformal coating. Consequently, you must install this module in a dust-free cabinet. Replace any relay after 100,000 switching cycles for reliability.
