The TM5SDO2DTRFS is a Modicon TM5 discrete output module from Schneider Electric, giving you two relay outputs rated at 6 A per channel on a common terminal, switchable from 5 to 230 V AC or 5 to 24 V DC. It fits a single-width 25 mm slot on the TM5 backplane. This module carries a safety integrity level of SIL 3 per IEC 61508 and IEC 62061, and PL e per EN 13849-1—so if your machine safety circuit calls for that rating, this block delivers it with a response time of 50 ms or less. The reliability data shows MTTFd over 100 years and PFH below 1E-9. The module is rated for operation in a 0 to 55 °C horizontal installation without derating, 0 to 60 °C with derating. Pollution degree 2, IP20 enclosure, and it passes 15 gn shock and 1 gn vibration on DIN rail.
Fit and key ratings – what matters for swap
25 mm wide, 75 mm deep, 99 mm high. One wire per output terminal. Electrically: 6 A per channel, resistive load curve. If your load exceeds 6 A per relay, this module is not a fit. The relay contacts are N.O. only (2 form A). No N.C. contact on board. Use for on/off control of solenoids, contactors, indicator lamps, or low-power motors via an external contactor. Safety architecture: if you need SIL 3 / PL e in your system, this module meets those targets. The PFD (<1E-5) and PFH (<1E-9) are diagnostics-friendly. Ensure your safety PLC or controller can accept the 50 ms response time in the safety function timing budget. The 2.3 W power dissipation is moderate. In a densely packed cabinet with limited airflow, that heat adds up; derate the ambient by 5 °C if the module is sandwiched between two high-power slices.
