Technical Specifications Overview

Functional Overview and Combined I/O Capability

This solid state I/O base combines 16 digital inputs and 12 digital outputs in a single module. It provides a compact solution for applications requiring both sensing and actuation. The TSXDMZ28DT integrates seamlessly with Modicon TSX Micro and Premium PLC systems. Moreover, the module uses solid state MOSFET technology for reliable, silent switching. This design eliminates contact wear for long service life. The module handles 24 VDC signals from sensors and also drives actuators directly. Consequently, it suits machine control, packaging, and material handling applications.

Input Characteristics and Signal Processing

The Schneider TSXDMZ28DT features 16 digital inputs with sink/source configurability. This flexibility accommodates both NPN and PNP sensor types without external components. Each input accepts voltages from 19.2 to 28.8 VDC with 7 mA typical current. The input delay of 1.5 ms provides fast response for normal control applications. The module includes software-selectable filtering to eliminate contact bounce and electrical noise. Each input channel has a green LED for real-time status indication. The LED simplifies troubleshooting during system commissioning and maintenance.

Output Characteristics and Protection Features

Twelve solid state outputs drive loads with 0.5 A continuous current per channel. Each output uses MOSFET technology for fast, silent switching. The outputs source current to connected loads such as relays, solenoids, and indicator lamps. The on-state resistance of 0.5 Ω minimizes power dissipation and heating. The module includes electronic short-circuit protection on every output channel. Additionally, thermal shutdown prevents damage from sustained overload conditions. The outputs also feature a leakage current below 0.1 mA for compatible device operation.

Physical Architecture and Installation Details

The module measures 45 mm x 120 mm x 75 mm (1.8″ x 4.7″ x 3.0″) and weighs approximately 0.22 kg. Its compact footprint saves valuable panel space in control enclosures. The front panel provides two removable spring clamp terminal blocks for field wiring. One terminal handles the 16 input channels and the other serves 12 outputs. Both terminals accept wire sizes from 0.5 to 1.5 mm². The module mounts on standard DIN rails using the integrated latch. The shallow 75 mm depth suits installation in space-constrained cabinets.

Status Indication and Diagnostic Features

The module features 28 front-panel LEDs for comprehensive I/O status monitoring. Sixteen green LEDs display the real-time status of each input channel. Twelve yellow LEDs show the state of each output channel. A single Power LED confirms correct supply voltage presence. The module also communicates diagnostic data through the system bus. Engineers can view detailed I/O status through Unity Pro or Concept software. The diagnostics include short-circuit detection and overtemperature warnings. The module automatically resets outputs after fault clearance.

Power Supply and Energy Storage Features

The module draws 50 mA from the 5 VDC system bus for logic circuits. It also requires 150 mA from a 24 VDC external supply for field I/O power. The internal 220 µF capacitor provides ride-through during brief interruptions. This capacitance ensures stable operation during momentary voltage dips. The module also includes reverse polarity protection on both power inputs. The output power supply connects through the terminal block for simple wiring.

System Integration and Configuration

The module connects directly to the TSX Micro and Premium system backplane. Schneider Unity Pro and Concept software provide seamless configuration and programming. Users can assign channel names, set filter times, and define alarm conditions. The module also supports online monitoring for real-time troubleshooting. Diagnostics data flows automatically to the PLC for continuous I/O health monitoring. The module reports all faults and alarms through the system bus.

Environmental Conditions and Certifications

The module operates reliably from 0°C to +55°C ambient temperature. Storage temperatures range from -25°C to +70°C. The unit carries CE, UL, and CSA certifications for global deployment. Install the module in a clean, dry control cabinet. The module also complies with IEC 61131-2 standards for programmable controller equipment.
