Discrete Input Modules | Schneider Electric TSXDEY16D3

The TSXDEY16D3 is a 16-channel 48 V DC current-sink discrete input module designed for the Modicon Premium automation platform. Operating across a sensor power supply range of 38 to 60 V DC, this standard-format module provides current-sinking input channels compliant with EN/IEC 61131-2 Type 2 requirements. It is engineered for higher-voltage direct current control applications, allowing reliable signal interfacing with 2-wire and 3-wire proximity sensors conforming to EN/IEC 60947-5-2 as well as industrial switch contacts.

Input Voltage Thresholds and Signal Processing

Each of the 16 isolated current-sinking input channels draws a nominal input current of 7 mA with an input impedance of 7,000 Ohms at state 1. The module guarantees signal processing with fast hardware response times between 4 ms and 7 ms. Input signal filtering ensures crisp detection of discrete field states, maintaining high noise immunity and stable communication with the central processing unit across noisy industrial operating conditions.

Power Dissipation, Electrical Isolation, and Hardware Specs

Field connections are made directly to the module using a screw terminal block. Powered by the system rack backplane, the module draws 80 mA at 5 V DC and 135 mA at 24 V DC. Total thermal power dissipation is calculated as 1 W base power plus 0.3 W for each active channel in use. The IP20-rated module features robust electrical isolation rated for a dielectric strength of 1,500 V AC at 50/60 Hz and an insulation resistance under 10 MOhm at 500 V DC. It operates reliably within ambient temperatures ranging from 0 deg C to 60 deg C.

Frequently Asked Questions

Q: What is the operating voltage range for the TSXDEY16D3 input module? A: The module is designed for a nominal 48 V DC positive current-sink voltage, with an acceptable external sensor power supply range of 38 V DC to 60 V DC.

Q: How do I calculate the total power dissipation of the TSXDEY16D3 module during operation? A: Base module power dissipation is 1 W. An additional 0.3 W is added for each active energized channel, giving a maximum thermal power dissipation of 5.8 W when all 16 channels are active simultaneously.
