The TM5SDO12T: Each channel drives up to 0.5 A continuous, and the common return can sink up to 6 A across the bank. The 12 A peak rating handles inrush from incandescent indicators or capacitive loads without a precharge resistor. Switching frequency is limited to ≤500 Hz on resistive loads; for inductive loads (solenoids, contactors), the turn-off time is the limiting factor at ≤300 µs. The module draws 52 mA from the 5 V backplane bus and 48 mA from the 24 V sensor supply — verify the head station's power budget adds up for your total slice count.
Physical fit and compliance
At 12.5 mm wide, the TM5SDO12T occupies exactly one slot. Depth is 75 mm, height 99 mm, with IP20 finger-safe housing. Mounted on a DIN rail, it tolerates 1 gn vibration at 8.4–150 Hz and 15 gn shock for 11 ms. Ambient operating temperature is –10 to +55 °C horizontal, derated to 50 °C vertical. Compliance covers CSA C22.2 No. 213, UL 508, and IEC 61131-2. EMC immunity includes 4 kV contact ESD, 10 V/m radiated field up to 2 GHz, and 2 kV fast transients on power lines.
The TM5SDO12T is listed as active — no last-time-buy or phase-out notice in effect. No direct drop-in replacement exists within the TM5 family; this is the standard transistor-output variant for 12-point source applications.
