Safety-rated discrete output for SIL 3 / PL e applications
The TM5SDO6TBFS is a Modicon TM5 safety DC discrete output module with six source outputs, each rated 0.2 A at 24 V DC (20.4...28.8 V). It carries SIL 3 certification per IEC 61508 and IEC 62061, and PL = e per EN 13849-1 — the highest performance level for safety-related control systems. Safety reliability data shows MTTFd > 100 years, PFD < 1E-5, and PFH < 1E-9, meaning the module is suitable for applications requiring continuous fault coverage without frequent proof-testing.
Output current and common limits
Each of the six outputs switches up to 0.2 A resistive at up to 500 Hz. The maximum current per output common is 2 A, so all six channels can be active simultaneously without exceeding the common rating. Peak output current is 12 A — useful for driving capacitive loads or short-duration inrush on solenoid valves, but the continuous per-channel limit governs steady-state wiring. Leakage current when switched off is 10 µA at 24 V DC, which prevents false activation of downstream loads in high-impedance circuits.
Standards and environmental fit
The module is CE marked and complies with UL 508, IEC 61131-2, CSA C22.2 No 142, EN 13849-1, IEC 61508, and IEC 62061. It is rated IP20, so it must be installed inside an enclosure with a minimum pollution degree 2 environment. Operating temperature range is 14...122 °F (-10...50 °C) for vertical mounting, or 14...131 °F (-10...55 °C) for horizontal installation. Storage range is -40...158 °F (-40...70 °C). Vibration resistance is 1 gn at 8.4...150 Hz on DIN rail, with 3.5 mm displacement at 5...8.4 Hz. Shock resistance is 15 gn for 11 ms — typical for industrial panel environments.
Diagnostics and wiring
Local signalling includes one green LED for power supply, one red LED for power supply, two red LEDs for safety status, and four red/orange LEDs for output status. This allows quick fault isolation without a programming terminal. Electrical connection uses 2-wire per channel, source logic. The module width is 25 mm (1.0 in), depth 75 mm (3.0 in), height 99 mm (3.9 in) — fits standard Modicon TM5 backplane slots.
Sourcing and lifecycle
No official successor or cross-reference is recorded — the module is the current safety output offering in the Modicon TM5 family. Availability and current pricing are confirmed at RFQ.
