TM5SAI2L 2-Channel Analog Input Module
Product Introduction
The TM5SAI2L is a compact analog input module from the Modicon TM5 platform. Schneider Electric built this module with two software-configurable 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 gives signed values from -32768 to +32767 for ±10 V ranges. Furthermore, accuracy stays within ±0.3% of full scale at 25 °C. The module also reports channel diagnostics such as wire break and limit alarms. This part carries an IP20 rating and fits clean control cabinets. Besides, it remains an active product in the Modicon TM5 line. Therefore, the TM5SAI2L suits both new builds and system expansions today.

Electrical and Diagnostic Features
Power comes from the TM5 bus through a power distribution module. Specifically, the module draws 2 mA at 5 Vdc and 5 mA at 24 Vdc. Power consumption stays at a low 0.81 W, so heat buildup remains minimal. Meanwhile, the diagnostics engine tracks several fault conditions. For instance, it flags values below the lower limit or above the upper limit. It also detects wire breaks on 4-20 mA loops. In addition, ModuleOK, DcOk and NetworkOk status bits help technicians trace faults fast. However, there is no isolation between the two channels. Therefore, installers should avoid large ground potential differences across channels.
Mechanical and Environmental Parameters
The module measures 99 mm high, 12.5 mm wide and 75 mm deep. Its slim body 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. 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.
Installation Guide
Installing the TM5SAI2L follows a straightforward procedure. First, snap the module onto the TM5 bus base. Next, connect the field wiring to the terminals. After that, set each channel's signal type in the engineering software. Then, choose the input cycle and filter level for your application. Moreover, enable wire break detection when you use 4-20 mA loops. Finally, verify the ModuleOK and NetworkOk LEDs before running the machine. If you replace an old module, label the wires first. This step prevents wiring errors during reassembly.
