Schneider Electric TSXDEY16A4 Discrete Input Module

The TSXDEY16A4 is a 16-channel AC discrete input module engineered for the Schneider Electric Modicon Premium automation platform. Operating at a nominal input voltage of 110 V AC, it provides precise digital signal acquisition from field switches and sensors for industrial control networks. The unit uses capacitive isolation to maintain high electrical noise immunity and protection across all 16 input channels.

Input Specifications and Sensor Compatibility

Designed in a standard Modicon Premium rack-mount format, the module features 16 capacitive isolated inputs compliant with EN/IEC 61131-2 Type 2 requirements. Each input accepts 110 V AC signals over a network frequency range of 47 to 63 Hz, with a sensor power supply range of 85 to 132 V AC. The module is fully compatible with 2-wire and 3-wire proximity sensors conforming to EN/IEC 60947-5-2, drawing a discrete input current of 12 mA per channel.

Electrical Characteristics and Signal Thresholds

To maintain accurate logic interpretation, state 1 (ON) is guaranteed at or above 74 V with a minimum current of 6 mA, while state 0 (OFF) is guaranteed at or below 20 V with a maximum leakage current of 4 mA. The input impedance is rated at 9200 ohms at state 1. The module draws 80 mA at 5 V DC from the backplane bus, with a total internal power dissipation of 0.83 W.

Environmental Design and Physical Properties

Field connections are made through integrated screw terminal blocks. Built for demanding industrial environments, the module features IP20 ingress protection, TC protective treatment, and an operating temperature range of 0 °C to 60 °C. It satisfies rigorous global safety and industrial standards, including UL 508, CSA Class I Division 2, and CE marking.
