TM5SPS3 Characteristics

General Characteristics

DANGER
	FIRE HAZARD Use only the correct wire sizes for the maximum current capacity of the power supplies. Failure to follow these instructions will result in death or serious injury.

WARNING
	UNINTENDED EQUIPMENT OPERATION Do not exceed any of the rated values specified in the environmental and electrical characteristics tables. Failure to follow these instructions can result in death, serious injury, or equipment damage.

The table below provides the general characteristics of the Interface Power Distribution Module (IPDM) TM5SPS3:

General Characteristics
Rated power supply voltage	24 Vdc
24 Vdc I/O power segment current draw	25 mA
Power dissipation	1.82 W maximum
Weight	30 g (1.1 oz)
ID code	8076 dec

TM5 Power Bus Characteristics

The table below provides the TM5 power bus characteristics of the Interface Power Distribution Module (IPDM) TM5SPS3:

TM5 Power Bus Characteristics
Power supply range	20.4...28.8 Vdc
Rated input current	0.7 A at 24 Vdc
Reverse polarity protection	Yes
Fuse	Integrated, cannot be exchanged
Current generated	On TM5 power bus: 750 mA To supply the field bus interface module: 300 mA
Electrical isolation	See note ¹
Parallel operation	Yes ²
¹ The isolation of the electronic module is 500 Vac RMS between the electronics powered by the TM5 bus and those powered by 24 Vdc I/O power segment connected to the module. In practice, the TM5 electronic module is installed in the bus base, and there is a bridge between the TM5 power bus and the 24 Vdc I/O power segment. The two power circuits reference the same functional ground (FE) through specific components designed to reduce effects of electromagnetic interference. These components are rated at 30 Vdc or 60 Vdc. This effectively reduces isolation of the entire system from the 500 Vac RMS. ² In parallel operation, only 75% of the rated power can be assumed. Ensure that all parallel operating power supplies are switched on and off simultaneously.

Temperature De-rating

The Interface Power Distribution Module (IPDM) TM5SPS3 is subject to temperature restrictions depending on the current consumption on the TM5 power bus:

up to 500 mA: 0...60°C (32...140°F)
over 500 mA: 0...55°C (32...131°F)

24 Vdc I/O Power Segment Characteristics

The table below provides the 24 Vdc I/O power segment characteristics of the Interface Power Distribution Module (IPDM) TM5SPS3:

24 Vdc I/O Power Segment Characteristics
Power supply range	20.4...28.8 Vdc
Rated power supply voltage	24 Vdc
Maximum current provided	10 A
Reverse polarity protection	No
Short circuit protection	External fuse type T slow-blow 10 A maximum 250 V
Isolation between power segment and TM5 buses	See note ¹
