Schneider TM5SAI4L Modicon TM5 Analog Input

TM5SAI4L 4-Channel Analog Input Module

Product Introduction

The TM5SAI4L is a compact analog input module from the Modicon TM5 platform. Schneider Electric built this module with four differential input channels. Each channel accepts ±10 Vdc, 0-20 mA or 4-20 mA signals. As a result, one module covers voltage and current sensor needs. The 12-bit resolution plus sign gives precise measurement across the full range. Furthermore, measurement error stays below 0.08% of full scale at 25 °C. The module also carries CE marking and multiple safety certifications. This part carries an IP20 rating and fits clean control cabinets. Besides, it remains an active product in the Modicon TM5 line. Therefore, the TM5SAI4L suits both new builds and system expansions today.

Electrical and Diagnostic Features

Power comes internally from the TM5 bus through a power distribution module. Specifically, the module draws 2 mA at 5 Vdc and 46 mA at 24 Vdc. Maximum power dissipation reaches 1.11 W, so heat buildup stays modest. Meanwhile, common mode rejection exceeds 70 dB, which reduces noise on long cable runs. The front panel carries one green power LED, one red power LED, and four green input status LEDs. However, there is no insulation between the four channels. Therefore, installers should avoid large ground potential differences across channels. In addition, always use shielded cable to meet the EMC standards.

Mechanical and Environmental Parameters

The module measures 99 mm high, 12.5 mm wide and 75 mm deep. Its slim white housing saves DIN rail space in crowded cabinets. Meanwhile, the unit weighs only 0.025 kg, which keeps shipping costs low. Operating temperature ranges from 0 to +55 °C without derating in horizontal installation. With derating, it reaches +60 °C horizontally and +50 °C vertically. Storage temperature spans -25 to +70 °C. The IP20 rating means the housing blocks solid objects larger than 12.5 mm. However, it does not resist water or dust ingress. For this reason, users should mount it inside a protected enclosure.

Standards and Compliance

The TM5SAI4L meets several international standards for industrial control equipment. These include IEC 61131-2, UL 508, and CSA C22.2 No 213. Product certifications cover CSA, cULus, GOST-R and C-Tick. Furthermore, the module resists electrostatic discharge at 4 kV contact and 8 kV air. It also withstands 15 gn shock for 11 ms and vibration on DIN rail. EMC performance follows EN/IEC 61000-4-3 for radiated fields and CISPR 11 for emissions.

Installation Guide

Installing the TM5SAI4L follows a straightforward procedure. First, snap the module onto the TM5 bus base. Next, connect the shielded field wiring to the terminals. After that, set each channel's signal type in the engineering software. Then, choose the sampling duration with or without filtering. Moreover, enable wire break detection when you use 4-20 mA loops. Finally, verify the power and input status LEDs before running the machine. If you replace an old module, label the wires first. This step prevents wiring errors during reassembly.
