Specifications Parameter Category Details Manufacturer & Series Schneider Electric, Modicon TM5 System (Standard Line) Complete Model Number TM5SDO16T Module Type 16-channel High-Speed Digital Transistor Output Module (Sourcing) Compatible Controllers Modicon M251 Logic Controllers (via a TM5 bus base unit), and other PLCs supporting the TM5 I/O system. Number of Channels 16 Output Type Sourcing (PNP) – 24V DC positive switching. Rated Load Voltage 24V DC Nominal Output Current per Channel 0.5 A Maximum Total Current per Module 4 A (shared across all 16 channels, with significant derating). Crucially, not all 16 channels can be used at full 0.5A simultaneously. Peak Current per Channel 2 A for 100 ms (inrush) Voltage Drop (On-state) Typically < 1.0 V at 0.5 A Leakage Current (Off-state) < 0.1 mA Switching Frequency Up to 100 Hz (for standard control). Some channels may support higher frequencies for pulse output (PWM). Response Time Typically < 1 ms (from command to physical state change). Short-Circuit & Overload Protection Yes, per channel. Electronic protection with diagnostic reporting to the controller. Diagnostics Per-channel diagnostic capability for short-circuit, overload, and open load (wire break) detection. Isolation 500V AC between field side (outputs) and logic/bus side. Typically no isolation between individual channels. Status Indicators • Module Status LED (Bicolor): RUN/ERR (Green/Red). • Channel Status LEDs (Green, one per channel): Indicates ON state of each output. Connection Removable screw terminal block (front connector) for field wiring. Power Supply Requires an external 24V DC power supply connected to the module's power terminals for the output circuits. The module logic is powered via the TM5 base unit. Power Consumption From 24V DC supply: Depends on the sum of all output currents (max 4A). From 5V bus (via base): ~100 mA. 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). Diagnostic parameters can be set per channel. Typical Applications Controlling banks of solenoid valves, pneumatic valves, indicator lamps, small DC relays, and other actuators in packaging machines, material handling systems, and automated assembly lines where fast and reliable switching is needed.
