Schneider Electric TM5SAI2H Analog Input Module

TM5SAI2H Modicon TM5 2-Channel Analog Input Module

Product Introduction

The Schneider Electric TM5SAI2H analog input module brings precision measurement capabilities to the Modicon TM5 I/O system. This white module features two differential analog inputs, each configurable for either ±10 V voltage or 0…20 mA current signals. With 16-bit resolution, it delivers accurate readings for a wide range of sensors and transmitters.

Specifically, the TM5SAI2H works seamlessly with Modicon M258 and LMC058 controllers, making it an ideal choice for motion control and logic applications. Its fast 50 µs sampling time ensures real-time responsiveness for demanding processes. Furthermore, the module includes local LED indicators for power and channel status, simplifying diagnostics and maintenance.

The module's white color coding identifies it as part of the TM5 analog I/O family, helping you quickly locate and service it within a crowded cabinet. Its compact design saves panel space while delivering professional-grade analog measurement performance.

Electrical Specifications and Accuracy

The TM5SAI2H offers impressive measurement precision. For voltage inputs, the resolution reaches 305 µV within the ±10 V range. For current inputs, resolution is 610 nA for the 0…20 mA range. Measurement error stays below 0.08% of full scale at 25 °C for both signal types, ensuring reliable data for your control algorithms.

The module's input impedance is a minimum of 20 MΩ for voltage signals, which minimizes loading on the sensor. For current signals, the load impedance is a maximum of 400 Ω. A temperature coefficient of 0.01% FS/°C maintains accuracy across varying ambient conditions. Non-linearity is below 0.01% of full scale for voltage and below 0.015% for current, providing consistent and repeatable measurements.

Additionally, the TM5SAI2H delivers a common mode rejection ratio greater than 70 dB, effectively filtering out noise from ground loops and other interference sources. The module draws 2 mA from the 5 V DC bus and 50 mA from the 24 V DC I/O power supply, with maximum power dissipation of only 1.21 W.

Installation and Compatibility

The TM5SAI2H is designed for easy integration into the Modicon TM5 system. It mounts on a standard symmetrical DIN rail, using the same locking mechanism as other TM5 modules. You can place it alongside other white-coded I/O modules for a cohesive system layout.

This module supports both horizontal and vertical mounting orientations. For horizontal installation, it operates from 0…55 °C without derating and up to 60 °C with derating. Vertical installation supports 0…50 °C. Always refer to your system's derating guidelines to ensure proper operation under all conditions.

Use shielded cables for the analog inputs to maintain signal integrity and minimize electromagnetic interference. The module provides no channel-to-channel insulation, so plan your wiring accordingly to avoid ground loops. However, it offers 500 Vrms AC isolation between channels and the bus, protecting the controller from field-side faults.

Environmental Durability and Compliance

The TM5SAI2H is built for demanding industrial environments. It operates within a relative humidity range of 5…95% without condensation and carries an IP20 protection degree per IEC 61131-2. The pollution degree is rated at 2 per IEC 60664, suitable for most control cabinet applications.

Vibration resistance is rated at 3.5 mm displacement from 5…8.4 Hz and 1 gn acceleration from 8.4…150 Hz on DIN rail. Shock resistance reaches 15 gn for 11 ms, making the module reliable in high-vibration settings. Operating altitude spans 0…2000 m, with storage altitude up to 3000 m and storage temperature from -25…70 °C.

Furthermore, this analog input module holds multiple certifications, including CSA, C-Tick, cULus, and GOST-R. It complies with key standards such as IEC 61131-2 and UL 508. As a Green Premium product, the TM5SAI2H is free from RoHS-restricted substances and REACh SVHC above threshold limits.

Packaging and Logistics

Each TM5SAI2H module comes in a single-unit package weighing only 0.025 kg. The compact packaging ensures safe transit and easy handling. For larger orders, bulk packaging options are available to reduce shipping costs and simplify inventory management.

All orders ship via trusted global couriers, including FedEx, UPS, and DHL. This guarantees fast and reliable delivery to your facility, wherever you are located. The product carries an 18-month warranty from Schneider Electric.
