What Is the TSXDMZ28AR?
Struggling with limited I/O points in your control system? The Schneider TSXDMZ28AR discrete I/O module provides a robust solution for expanding your PLC capabilities. Part of the Modicon TSX Micro automation platform, this module combines 16 discrete inputs and 12 relay outputs in a single compact unit. It operates reliably across a wide temperature range of -25°C to +70°C, making it suitable for demanding industrial environments.
Technical Specifications Breakdown
The TSXDMZ28AR delivers precise performance with key specs that matter:
- Input Voltage: 100...120 V AC at 47...63 Hz, with input limits of ≥74 V for state 1 and <20 V for state 0.
- Input Current: 11 mA at 50 Hz and 13 mA at 60 Hz, ensuring consistent signal detection.
- Response Time: Output response <10 ms; input response varies from 9...18 ms (state 0 to 1) and 10...24 ms (state 1 to 0) depending on frequency.
- Output Voltage Limits: 19...264 V AC or 10...34 V DC, with NO contact type.
- Power Consumption: 3 W (module) and 5.6 W dissipation; VA ratings range from 24 VA to 220 VA for resistive and inductive loads.
- Isolation: 500 V AC between channels and logic, plus 1500 V for 1 s isolation voltage.
- Certifications: CE, UL, CSA for global compliance.
These parameters ensure reliable switching and signal integrity in automation tasks.
Industry Applications
In manufacturing lines, the TSXDMZ28AR handles machine control sequences—like conveyor monitoring or part detection—using its 16 AC inputs and 12 relay outputs. Its fast response time (<10 ms output) suits high-speed sorting systems. For building automation, the module controls HVAC actuators or lighting relays, leveraging its wide output voltage range (19...264 V AC) for compatibility with various loads.
Installation & Setup Guidance
Mount the TSXDMZ28AR on a standard DIN rail in your control cabinet. Connect 100...120 V AC inputs via the screw terminal block, ensuring wiring meets local codes. For outputs, use appropriate fusing per load type (resistive or inductive). Verify that input voltage stays within ≥74 V for state 1 and <20 V for state 0 to avoid false signals. Keep the module in environments with 5% to 95% non-condensing humidity for optimal performance.
Maintenance & Reliability
Periodically inspect the module for dust accumulation on terminals, as this can affect signal integrity. The TSXDMZ28AR’s isolation (500 V AC between channels and logic) minimizes cross-talk, reducing false triggers. With storage tolerance from -40°C to +85°C, it withstands harsh conditions when not in use. Regular testing of relay outputs under rated loads (e.g., 220 VA resistive at 220 V AC) ensures long service life.
Compatibility & Integration
The TSXDMZ28AR integrates seamlessly with Modicon TSX Micro PLCs. It supports 2-wire proximity sensors for input compatibility. The module’s 16 inputs and 12 relay outputs connect directly to the PLC backplane, requiring no additional adapters. For system expansion, pair it with other TSX Micro discrete or analog modules.
Buying Guide
Before purchasing the TSXDMZ28AR, verify your PLC model compatibility with the TSX Micro series. Check that your application’s input voltage matches 100...120 V AC and that relay output loads stay within VA ratings (e.g., 220 VA max for resistive AC loads). SpareTechPLC stocks this module with fast shipping and expert support to help you select the right I/O configuration.
