Specifications Parameter Category Details Manufacturer & Series Schneider Electric, Modicon TM5 System (Essential Line) Complete Model Number TM5SAO4L Module Type 4-channel Analog Current Output Module Compatible Controllers Primarily Modicon M251 Logic Controllers (via a TM5 bus base unit), also compatible with other PLCs supporting the TM5 I/O system. Number of Channels 4 Output Signal Type Current Output Supported Current Ranges 0 to 20 mA and 4 to 20 mA (software configurable per channel). Resolution 12 bits Output Accuracy Typically ±0.3% of full scale (at 25°C / 77°F). Load Compliance Voltage Maximum load resistance (compliance): Typically 500 Ω for the 20 mA range. (e.g., 24V supply allows up to ~500Ω @ 20mA). Short-Circuit Protection Yes, per channel. The module is protected against indefinite short circuits to ground. Open-Circuit Detection Yes, the module can detect and report an open wire condition on the output loop. Isolation Channel-to-channel isolation: Yes. Channel-to-backplane (bus) isolation: 500V AC. Update Time per Channel Typically 3 ms. Data Format • For 4-20 mA range: 0 to 27648 (corresponding to 4mA = 0, 20mA = 27648). • For 0-20 mA range: 0 to 27648 (corresponding to 0mA = 0, 20mA = 27648). Status Indicators • Module Status LED (Bicolor): RUN/ERR (Green/Red). • Channel Status LEDs (Green, one per channel): Indicates channel activity or fault. Connection Removable screw terminal block (front connector) for field wiring. Power Supply Requires an external 24V DC power supply for the output circuits, connected to the module's power terminals. The module logic is powered via the TM5 base unit. Power Consumption From 24V DC supply: Depends on the sum of all output currents. Operating Temperature 0°C to +55°C Storage Temperature -25°C to +70°C Relative Humidity 5% to 95% (non-condensing) Protection Rating IP20 (for installation inside an enclosure). Mounting Mounts on a compatible TM5 bus base unit (e.g., TM5ABD1), which is then mounted on a DIN rail (35mm). Configuration Automatically detected and configured by the controller's programming software (EcoStruxure Machine Expert - Basic). Output range and behavior are set per channel in software. Typical Applications Controlling proportional valves, variable frequency drive speed references, I/P (current-to-pressure) transducers, fan coil units, and recording instruments in process control, HVAC, and industrial automation systems.
