It is built to safety-instrumented use: SIL 3 per IEC 61508 and IEC 62061, PL = e per EN 13849-1, with a PFD under 1E-5, PFH under 1E-9, and an MTTFd of 2500 years — the numbers that decide whether the device is acceptable on a safety loop at all. Form factor is the standard TM5 width — 25 mm wide, 75 mm deep, 99 mm tall — so it drops onto the same TM5 power distribution and bus segment as the rest of the slice I/O. ## Inputs and outputs, in the loop Inputs are sinking, draw 2.48 mA at 24 V DC from a 9.68 kOhm input impedance network, and read guaranteed logic 1 above 15 V and logic 0 below 5 V at the terminal — so the call-out voltage from a safety device or contact needs to clear those rails cleanly. Hardware input filtering is capped at 150 ms, which is the latency the safety calculation must absorb; if the upstream safety sensor (E-stop, guard interlock) is faster than this, it is harmless, but slow mechanical switches need to be evaluated against this floor. Outputs are two source 24 V DC transistor channels in the 20.4 to 28.8 V range — drive 24 V loads (contactors, signal lamps, small valve solenoids) sourcing current, not sinking it. ## Cabinet environment Operating ambient runs 0 to 50 °C on a vertical mounting or 0 to 55 °C horizontal; storage spans −40 to 70 °C — the upper number on storage is what governs truck/warehouse handling in winter, not in-cabinet operation. Mounting tolerated up to 2000 m altitude, with vibration 1 gn across 8.4 to 150 Hz on DIN rail, 3.5 mm amplitude from 5 to 8.4 Hz, 15 gn shock for 11 ms, and 5 to 95 % non-condensing humidity — standard cabinet-grade, no sealed enclosure required. Pollution degree 2 and IP20 mean an enclosed cabinet or control room is mandatory; do not mount in a washdown or dusty-from-process location without a separate enclosure. EMC compliance covers IEC 61000-4-2 (4 kV contact / 8 kV air ESD), IEC 61000-4-3 (10 V/m 80 MHz to 2 GHz radiated), IEC 61000-4-4 (1 to 2 kV bursts on shielded cable, I/O, and power), IEC 61000-4-5 (0.5 kV differential / 1 kV common surge), IEC 61000-4-6 (conducted RF), with CISPR 11 emissions — so it sits next to VFDs and switching contactors provided the cabinet bonding and cable shielding follow the standard IEC practice. ## Diagnostics on the door Front-of-module LEDs split the diagnostics cleanly: one green LED per power supply rail, two red LEDs for safety status, two red/orange LEDs for each output channel, and six green/red LEDs for the input channels — so the field tech can read which leg of the safety circuit is not making without logging into the controller. ## Sourcing posture Spec-thin residual angles — RoHS/REACH/UL files or direct part-number cross references inside the TM5 family — are not on this ledger, so no claim is made about either RoHS/REACH compliance documents or a pin-compatible sibling in this entry; a quoted RFQ is the right path for both.","metaTitle":"Schneider TM5SDM8TBFS Safety I/O Module, 6DI/2DO","metaDescription":"Schneider TM5SDM8TBFS Modicon TM5 safety discrete I/O module: 6 sink inputs and 2 source transistor outputs, SIL 3 / PL e, supplied on quoted RFQ.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":[],"specifications":{"Depth":"3.0 in (75 mm)","Width":"1.0 in (25 mm)","Height":"3.9 in (99 mm)","Marking":"CE","Category":"US1PC5218353","Standards":"CSA C22.2 No 142 EN 13849-1 IEC 61508 IEC 62061 IEC 61131-2","Safety level":"SIL 3 IEC 61508 SIL 3 IEC 62061 PL = e EN 13849-1","Input filtering":"<= 150 ms hardware","Input impedance":"9.68 kOhm","lifecycle_stage":"current","Local signalling":"1 LED (green) for power supply 1 LED (red) for power supply 2 LEDs (red) for safety status 2 LEDs (red/orange) for output status 6 LEDs (green/red) for input status","Pollution degree":"2","Range of Product":"Modicon TM5","Shock resistance":"15 gn 11 ms","Relative humidity":"5...95 % without condensation","Operating altitude":"0...6561.68 ft (0...2000 m)","Discrete input logic":"Sink","Vibration resistance":"1 gn 8.4...150 Hz) on DIN rail 3.5 mm 5...8.4 Hz) on DIN rail","Discrete input number":"6","Discrete output logic":"Source","Electrical Connection":"2 wires","Nbr. of units in pkg.":"1","Discrete input current":"2.48 mA at 24 V DC","Discrete input voltage":"24 V DC 20.4...28.8 V)","Discrete output number":"2","Discrete output voltage":"24 V DC 20.4...28.8 V)transistor","IP Degree of Protection":"IP20","Safety reliability data":"PFD < 1E-5 PFH < 1E-9 MTTFd = 2500 years","Product or Component Type":"Safety discrete I/O module","Voltage state 0 guaranteed":"<= 5 V","Voltage state 1 guaranteed":">= 15 V","Electromagnetic compatibility":"Electrostatic discharge immunity test, 4 kV on contact IEC 61000-4-2 Electrostatic discharge immunity test, 8 kV in air IEC 61000-4-2 Susceptibility to electromagnetic fields, 10 V/m 80...2000 MHz IEC 61000-4-3 Electrical fast transient/burst immunity test, 1 kV I/O IEC 61000-4-4 Electrical fast transient/burst immunity test, 1 kV shielded cable IEC 61000-4-4 Electrical fast transient/burst immunity test, 2 kV power lines IEC 61000-4-4 1.2/50 µs shock waves immunity test, 0.5 kV differential mode IEC 61000-4-5 1.2/50 µs shock waves immunity test, 1 kV common mode IEC 61000-4-5 Conducted RF disturbances IEC 61000-4-6 Conducted and radiated emissions CISPR 11","Ambient air temperature for storage":"-40...158 °F (-40...70 °C)","Complementary/Discrete input number":"6 at 24 V DC","Complementary/Discrete output number":"2 transistor at 24 V DC","Ambient air temperature for operation":"32...122 °F (0...50 °C) vertical installation) 32...131 °F (0...55 °C) horizontal installation)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$835.00","priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/d30ed2db648cc5465895295c3675746d.pdf","sourceUrl":null,"alternativesUrl":"https://aoctrl.com/api/mcp/products/TM5SDM8TBFS/alternatives.json"},"ai":{"faq":[{"question":"What is the listed footprint?","answer":"25 mm wide, 75 mm deep, 99 mm tall — the standard TM5 slice width, dropping onto the same bus and power distribution as the rest of the modular I/O."},{"question":"What safety level does it carry?","answer":"SIL 3 per IEC 61508 and IEC 62061, PL = e per EN 13849-1, with PFD under 1E-5, PFH under 1E-9, and MTTFd of 2500 years."},{"question":"What EMC and environmental ratings apply?","answer":"IEC 61000-4-2 through 61000-4-6 plus CISPR 11 emissions;
