The TM5SDO2TFS is a safety-rated DC discrete output module from the Modicon TM5 family – two solid-state source outputs, each rated 0.5 A continuous with a peak capability of 12 A. It switches loads on the 24 V DC control voltage rail, and the outputs are watchdog-monitored for safety logic. It carries SIL 3 per IEC 61508 and IEC 62061, and PL e per EN 13849-1. The safety reliability data shows MTTFd > 100 years, PFD < 1E-5, PFH < 1E-9 – numbers that slot easily into a risk-assessment report without extra derating. The module occupies a single 25 mm wide slot in the TM5 backplane and draws power from the bus. It is IP20-protected, rated for pollution degree 2, and has a switching frequency up to 500 Hz for resistive loads. Off-state leakage is 10 µA at 24 V – negligible for most safety circuits.
This module mounts directly into a TM5 bus base and communicates over the backplane with the safety PLC or safety CPU. There are no fieldbus settings to configure. Installation rules: vertical mounting allows an ambient temperature range of -10 to 50 °C; horizontal (sideways) extends to 55 °C. Vibration resistance is 1 gn on DIN rail across 8.4–150 Hz. The module meets IEC 61131-2 and carries CE marking, UL 508, and CSA C22.2 No 142.
