TM5SDI20DFS Characteristics

Introduction

This section describes the characteristics of the TM5SDI20DFS 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.

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 TM5SDI20DFS module:

Operating conditions

Mounting orientation

horizontal or vertical

Operating temperature

0 up to 2000 m (0 up to 6561 ft)

no derating for altitude

> 2000 m (>6561 ft)

reduction of ambient temperature by 0.5 °C per 100 m (0.9 °F per 328 ft)

EN 60529 protection type

IP20

1 Derating in relation to operating temperature and mounting orientation

Horizontal installation, 0...+55 °C (+32...131 °F)

Vertical installation, 0...+50 °C (+32...122 °F)

IN = number of inputs to be used simultaneously

T = temperature

NOTE: If a TM5SD000 is installed on the side of the module, the horizontal installation derating is shifted to the right by the following derating bonus:

  • TM5SD000 to the left: +0 °C (+0 °F)

  • TM5SD000 to the right: +2.5 °C (+4.5 °F)

  • TM5SD000 to the left and right: +5 °C (+9 °F)

NOTE: Using a TM5SD000 does not provide a derating bonus in vertical installation.
