Schneider XPSVNE1142P Preventa 24VDC Zero Speed Safety Relay Module

The Schneider Electric Preventa safety relay module XPSVNE1142P is used to safely monitor and switch motor power supplies up to 60 Hz. It runs on 24 V DC and can detect motors that are not moving. It has relay and solid-state safety outputs that can be used in safety circuits that meet performance level d / SILCL 2 standards. ​

Overview of XPSVNE1142P Module:

• Brand: Schneider Electric (the Preventa Safety automation series). ​
• The product type is the Preventa safety module, the zero-speed detection module XPSVN, and the part number is XPSVNE1142P. ​
• Common use: Keeping an eye on the zero speed of 3-phase or DC motors (including star-delta and variable speed drive systems) to manage safety features like guard doors, brakes, or safe entry after run-down. ​

Function and performance of safety

-> This module detects zero speed for various types of motors, including 3-phase motors that start with or without a star-delta configuration, motors with a variable number of poles, motors equipped with variable speed drives, DC motors, and those used in combination with XPS AK modules.

-> Safety levels: When used as directed in the datasheet, it can meet performance level d, category 3 under EN/ISO 13849-1 and SILCL 2 per EN/IEC 62061, with diagnostic coverage above 99%. ​

Electrical Characteristics

• Rated supply voltage: 24 V DC, with a range of −15% to +10%
• Power use: About 3.5 W when it’s running
• Inputs: A zero-speed sensing input with a detection threshold of about 0.01 to 0.1 V, depending on the motor feedback signal, is rated at 500 Vrms. ​

Outputs and contacts

Setting up the output:

• 1 safety relay output with 1 NO and 1 NC volt-free contact for switching power and control
• Two solid-state (semiconductor) outputs for signaling or connecting to a PLC

Ratings for relays:

• The relay output may handle up to 2.5 A of normal thermal current, and the fuse must be 4 A gG per EN/IEC 60947‑5‑1
• For AC-15 C300 duty, the breaking capacity is about 180 VA holding and 1800 VA inrush. For DC-13, it can be up to 1.2–1.5 A at 24 V, depending on the NO/NC contact

-> Minimums: To make sure that switching works, the minimum relay output current should be about 10 mA and the minimum relay output voltage should be about 17 V. ​

Indicators, links, and mechanics:

• Local indication: Four LEDs on the front panel show the status of the supply, the input, and the output for easy troubleshooting
• Terminals: Removable captive screw-clamp terminal blocks that can hold solid or flexible conductors that are around 0.2 to 2.5 mm², depending on how the wires are set up (single or double wires, with or without ferrules)
• Mounting: 35 mm DIN rail mounting that is symmetrical for easy installation in control panels

Envirnmental Data

• Protection for the enclosure: IP40 for the housing and IP20 for the terminals, according to EN/IEC 60529. This makes it safe to install within a control cabinet. ​
• The temperature range for operation is around −10 to 55 °C, while the range for storage is roughly −25 to 85 °C. ​
• Size and weight: The width is about 45 mm, the height is about 99 mm, the depth is about 114 mm, and the net weight is about 0.5 kg. ​
