TM5SPS2 Characteristics

Introduction

This section gives the TM5SPS2 electronic module characteristics.

DANGER
	FIRE HAZARD Use only the correct wire sizes for the maximum current capacity of the I/O channels and power supplies. For relay output (2 A) wiring, use conductors of at least 0.5 mm² (AWG 20) with a temperature rating of at least 80 °C (176 °F). For common conductors of relay output wiring (7 A), or relay output wiring greater than 2 A, use conductors of at least 1.0 mm² (AWG 16) with a temperature rating of at least 80 °C (176 °F). Failure to follow these instructions will result in death or serious injury.

For common conductors of relay output wiring (7 A), or relay output wiring greater than 2 A, use conductors of at least 1.0 mm² (AWG 16) with a temperature rating of at least 80 °C (176 °F).

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.

General Characteristics

The following table shows the general characteristics of the TM5SPS2 electronic module:

TM5 Power Bus Characteristics

The following table shows the TM5 power bus characteristics of the TM5SPS2 electronic module:

TM5 Power Bus Characteristics

Power supply range

20.4...28.8 Vdc

Rated input current

0.7 A maximum at 24 Vdc

Reverse polarity protection

Yes

Fuse

Integrated, can not be exchanged

Current generated

1136 mA

Parallel operation

Yes ²

Electrical isolation

See note ¹

1	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 or 60 V.
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

These electronic modules are subject to temperature restrictions on TM5 power bus current generated

0...55 °C (32...131 °F): 1136 mA
55...60 °C (131...140 °F): 740 mA

24 Vdc I/O Power Segment Characteristics

The following table shows the 24 Vdc I/O power segment characteristics of the TM5SPS2 electronic module:

24 Vdc I/O Power Segment Characteristics
Power supply range	20.4...28.8 Vdc
Rated power supply voltage	24 Vdc
Maximum current provided	10000 mA
Reverse polarity protection	No
Short circuit protection	External fuse type T slow-blow 10 A maximum 250 V
Isolation between power segment and TM5 power and data buses	See note ¹

¹ The isolation of the electronic module is 500 Vac RMS between the electronics powered by TM5 power bus and the part powered by 24 Vdc I/O power segment connected to the module. In practice, the TM5 module is installed in the bus base, and there is a bridge between TM5 power bus and 24 Vdc I/O power segment. The two power circuits reference the same functional ground (FE) through specific components designed to reduce the effects of electromagnetic interference. These components are rated at 30 or 60 V. This effectively reduces isolation of the entire system from the 500 Vac RMS.
