Schneider TSXPAY262 Preventa Safety Module

The Schneider TSXPAY262 monitors emergency stop circuits for Modicon PLC systems. This Preventa safety module provides two independent safety channels. You will find it in machinery requiring SIL 3 or PL e protection. It detects wiring faults and contact welding conditions automatically. Therefore, this unit ensures safe machine operation for personnel protection.

This module measures 130 mm in height and 45 mm in width. Its depth reaches 100 mm for standard rack mounting. The unit weighs approximately 0.34 kilograms. It contains two redundant safety relays and four status LEDs. Three forced-guided relay contacts provide the safety outputs. Additionally, you get one auxiliary contact for status feedback.

Internal Architecture and Energy Storage

The Schneider TSXPAY262 stores minimal energy in its power supply filter. Small electrolytic capacitors hold approximately 180 microfarads total capacitance. Two redundant safety relays operate in series for each output channel. These relays feature forced-guided contacts for diagnostics. A microprocessor monitors both input channels continuously. This processor checks for discrepancies and timing errors. The module performs a self-test on every power-up cycle. A yellow FAULT LED indicates internal or wiring errors.

Connection Interfaces and Wiring Details

You will find a 16-pin removable terminal block on the bottom. This block accepts two emergency stop inputs and output wiring. Connect the 24 VDC supply to the A1 and A2 terminals. Wire the first E-stop channel to terminals S11 and S12. Wire the second E-stop channel to terminals S21 and S22. The Schneider TSXPAY262 requires dual-channel wiring for SIL 3 compliance. Use shielded cable for input runs longer than 10 meters. Four LEDs show power, channel status, and fault conditions. A green PWR LED lights up when the module receives 24 VDC. Two yellow LEDs indicate each safety channel is closed.

Configuration and Installation Steps

You slide this module into any I/O slot of the Modicon rack. First, align the module with the upper and lower card guides. Then, push it firmly until the backplane connector seats completely. Secure the front panel with the two retaining screws. Connect all safety wiring before applying power to the system. The Schneider TSXPAY262 requires manual reset after each safety event. Wire a momentary pushbutton to the reset input terminals. Do not bypass or short any safety input channels. Test the complete safety circuit before machine startup. The module auto-configures without any software settings.
