Schneider Electric TM171EP14R Modicon M171 I/O Expansion Module, 14 Inputs/Outputs, 24V AC/DC

Description

Features

• This performance expansion module instantly adds 14 built-in I/O points to your setup, featuring 4 digital inputs, 4 analog inputs, 4 digital outputs, and 2 analog outputs. It allows you to scale up complex HVAC or pumping automation machinery effortlessly without the financial burden or footprint of buying a completely new primary controller.
• Equipped with an embedded CAN expansion bus port utilizing a robust screw terminal block, the module guarantees high-speed, noise-resistant data communication across your network. This dedicated industrial fieldbus architecture prevents latency issues and ensures reliable real-time telemetry between the main processor and secondary field devices.
• The 4 highly versatile analog inputs are configurable by pair and natively support 0-5V ratiometric, 0-10V voltage, 4-20mA current, as well as NTC and PTC temperature sensors. This broad compatibility eliminates the need for expensive external signal converters or signal conditioning cards, allowing you to wire existing environmental probes directly to the terminal block.
• This module features 1 heavy-duty SPDT relay output with an independent common alongside 3 SPST relay outputs sharing a single common, all rated for a 3 A discrete output current at 24V AC/DC. This versatile contact configuration gives you the flexibility to safely isolate critical loads or switch multi-stage compressors, fans, and valves from a single compact block.
• Designed for high-density control panels, the ultra-compact housing measures just 70mm wide, 87mm high, and 61.6mm deep, snap-mounting onto standard 35mm DIN rails. Its space-saving layout dramatically reduces panel real estate requirements while maintaining an IP20 protection rating to shield internal components from dust during routine maintenance.
• Built to meet rigorous global standards, this expansion module carries official CE, cURus, CSA, EAC, and RoHS China certifications. These credentials guarantee compliance with municipal and facility electrical codes, ensuring your automated systems clear inspections smoothly while protecting your upstream equipment from electrical faults.
