TM5SPS2 - Modicon TM5 Power Distribution Module, 24 V DC, 10 A I/O Power

Product type: Power Distribution Module  |  Range: Modicon TM5  |  Supply: 24 V DC  |  I/O power section: 10 A  |  Width: 12.5 mm  |  I/O points: none

The TM5SPS2 is a power distribution module of the Modicon TM5 system. It carries no I/O points and handles no process signal: it feeds a fresh 24 V DC supply into the TM5 power bus and into the I/O power section at the point where it is fitted in the island, so the supply can be renewed part way along a long assembly instead of being taken only from the head station. It is used on islands built around the Modicon LMC058 and Modicon M258 controllers, and it also allows the I/O power to be split into separately supplied sections inside one island.

The rated supply voltage is 24 V DC. On the I/O power section the module delivers 10 A and the input current on that section is 10 A, which is the value used to size the upstream feed and its protection. On the TM5 power bus the datasheet gives two output ratings, 1136 mA and 740 mA. Short-circuit protection is provided by a 10 A external fuse, which has to be fitted by the user; the module does not contain the fuse. Typical consumption of the module itself is 25 mA at 24 V DC and maximum power dissipation is 1.91 W, so the heat it adds inside the cabinet is small compared with the load it feeds.

Because the module is a distribution point and not a converter, the 24 V DC has to be brought to it as a separate feed, protected against short circuit by the 10 A external fuse, and the total current drawn by the modules downstream of it has to stay inside the 10 A rating of the I/O power section. In an island where the I/O supply has to be switched off in sections while the controller keeps running, the TM5SPS2 is the reference that creates that boundary, since each distribution point defines where its own I/O supply begins.

The housing is grey and 12.5 mm wide, the standard TM5 slice width, so the module occupies one position on the rail. Height is 99 mm and depth is 75 mm, and net weight is 0.03 kg. Field wiring lands on a screw or spring terminal block. Protection degree is IP20, so the module is made for mounting inside a closed enclosure on a DIN rail. The compact size and the 1.91 W dissipation mean it can be fitted between I/O slices without extra spacing.

Ambient temperature for operation is −10 to 55 °C without derating in vertical mounting, 55 to 60 °C with derating, and −10 to 50 °C in vertical mounting. Storage temperature is −25 to 70 °C, relative humidity 5 to 95 % without condensation, operating altitude 0 to 2000 m and pollution degree 2. Vibration resistance is 1 gn from 8.4 to 150 Hz and 3.5 mm from 5 to 8.4 Hz on metallic parts, shock resistance is 15 gn for 11 ms. The module is marked CE and certified CSA, C-Tick, CULus and GOST-R, and conforms to UL 508, CSA C22.2 No 213, CSA C22.2 No 142 and IEC 61131-2. One piece is packed in a 10.5 x 6 x 2 cm carton of 50 g, and the contractual warranty is 18 months.
