Output Design and Switching

The Schneider TSXDSY08T31 uses eight P-channel MOSFETs for DC load switching. Each output sources current from the positive supply to the load (sourcing configuration). A 0.5 ms turn-on time provides fast response for high-speed applications. Red LEDs illuminate when their corresponding outputs energize.

Performance Characteristics

Each output handles 0.5 Amps of continuous DC current at 24 VDC. The total module load should not exceed 4 Amps across all eight points. Short-circuit protection automatically shuts down any overloaded output channel. Thermal shutdown activates if any MOSFET exceeds safe operating temperatures.

Isolation and Noise Immunity

Optical isolators separate each output channel from the internal logic side. This 1500 VAC rating prevents noise from corrupting the PLC backplane. The design eliminates ground loops between the controller and field devices. Consequently, the module performs reliably in electrically noisy industrial environments.

Installation and Wiring

Mount this module in any I/O slot of a TSX Premium rack. The 20-pin removable terminal block accepts wires from 16 to 22 AWG. For best results, use copper conductors rated for 75°C minimum. You should also install a suppression diode across each inductive load to protect the output transistor.

Compatibility and Application

This module fits TSX Premium 57 series rack systems exclusively. It occupies a single slot in the controller configuration. You can mix this unit with other TSX discrete or analog modules freely. For best results, use Unity Pro or PL7 Pro software for module configuration.

Visual Status Indication

Eight red LEDs on the front panel show the real-time output status. Each LED illuminates when its corresponding transistor receives a turn-on signal. Therefore, technicians can verify output operation without a multimeter. A green LED indicates that the module has backplane power.

Energy Storage and Protection

A 100 µF capacitor maintains output logic during brief power interruptions. Each channel includes built-in overcurrent protection against short circuits. The module automatically restores output operation once the fault clears. This design protects both the module and your connected field devices from damage.

Why Choose This Module

This sourcing output module suits European and Asian machine designs perfectly. Its fast 0.5 ms response handles high-speed packaging and labeling equipment. Therefore, this unit works well for conveyors, pick-and-place machines, and assembly fixtures.
