TM5SDI2DFS Characteristics

Introduction

This section describes the characteristics of the TM5SDI2DFS module. See also TM5 Environmental Characteristics.

DANGER
	FIRE HAZARD Use only the correct wire sizes for the maximum current capacity of the I/O channels and 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.

General Characteristics

The following table lists the general characteristics of the TM5SDI2DFS module:

General Characteristics
Rated power supply voltage		24 Vdc
Integrated protection		Reverse polarity protection
Status indicators		I/O functions per channel operating state module status
Diagnostics		Module run and detected error conditions indicated by status LED indicator and software status.
Electrical isolation⁽¹⁾	channel - bus	See note.
Electrical isolation⁽¹⁾	channel - channel	no galvanic isolation
TM5 Bus 5 Vdc current draw		50 mA
24 Vdc I/O segment current draw		41.7 mA
Certifications and standards		Refer to www.se.com for the latest information regarding certifications and standards.
Maximum internal cycle time		800 µs
Minimum cycle time		200 µs
Minimum I/O update time		400 µs
Minimum safety-related response time		6 ms
Id code for firmware update		7957 dec

NOTE ⁽¹⁾ The isolation of the electronic module is 500 Vac RMS between the electronics power by the TM5 bus and those powered by 24 Vdc I/O power segment connected to the module. In practice, the 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.

Operating Conditions

The following table lists the operating conditions for the TM5SDI2DFS module:

Operating Conditions
Mounting orientation		horizontal or vertical

NOTE ⁽¹⁾ The isolation of the electronic module is 500 Vac RMS between the electronics power by the TM5 bus and those powered by 24 Vdc I/O power segment connected to the module. In practice, the 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.
