TM5SAO2L Schneider Electric 2-Ch Analog Output Module

Product Overview: TM5SAO2L Analog Output Module

When an application demands exact analog actuation, the TM5SAO2L from Schneider Electric provides engineering-grade precision across two independently configurable output channels. As part of the Modicon TM5 distributed I/O platform, this module converts digital control data into ±10 Vdc or 0-20 mA signals. Consequently, engineers can drive proportional valves, variable-frequency drives, and positioners with verified 12-bit resolution. The TM5SAO2L therefore suits both new machine builds and targeted expansions of existing Modicon installations.

Key Specifications and Performance Data

Each channel operates in voltage or current mode, selected through software configuration. The table below summarizes the verified electrical and environmental parameters.

• Output channels: 2, independently configurable
• Signal range: ±10 Vdc or 0-20 mA per channel
• Resolution: 12 bits
• Accuracy: ±0.3% of full scale at 25 °C
• Supply voltage: 24 Vdc via TM5 bus
• Isolation: 500 Vrms AC between channels and bus
• Response time: 1 ms max. output change; 200 µs sampling
• Operating temperature: 0 to +55 °C
• Protection rating: IP20

Notably, the 200 µs sampling interval supports control loops that require fast reaction to setpoint changes. Meanwhile, the 500 Vrms AC isolation between channels and bus protects the controller side from field transients. Because there is no isolation between the two output channels, both channels share a common reference. Engineers should account for this during wiring design.

Integration with Modicon Control Platforms

The TM5SAO2L integrates directly with Modicon M241, M251, M258, and LMC058 platforms through the TM5 bus. Power consumption is 1.11 W. Bus current draw is 2 mA at 5 V DC and 46 mA at 24 V DC. The module reports ModuleOK, DcOk, and NetworkOk diagnostics, so maintenance teams can verify health status without external test equipment. When commissioning, confirm that the controller firmware recognizes the module and that channel configuration matches the connected actuator. For fieldbus architectures beyond the local TM5 bus, consult Schneider Electric documentation for supported network gateways.

Applications and Engineering Fit

Typical applications include proportional hydraulic valve control, analog speed references for drives, and positioner command signals in packaging and material handling machinery. In each case, the 12-bit resolution provides 4096 discrete steps across the configured range, which supports smooth actuation without visible stepping. Furthermore, the ±0.3% full-scale accuracy at 25 °C helps maintain process consistency. Because the module occupies only 12.5 mm of DIN rail width and weighs 0.025 kg, panel space remains efficient in dense I/O configurations.
