TM5SDO4TAFS Characteristics

Introduction

This section describes the characteristics of the TM5SDO4TAFS 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 TM5SDO4TAFS module:

Operating Conditions

Mounting orientation

horizontal or vertical

Operating temperature

horizontal installation

0...+55 °C (+32...131 °F)

Derating horizontal:

x-axis: Ambient temperature [°C]

y-axis: Output current [A]

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: +2.5 °C (+4.5 °F)

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

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

vertical installation

0...+45 °C (+32...113 °F)

Derating vertical:

x-axis: Ambient temperature [°C]

y-axis: Output current [A]

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

Relative humidity

5...95%, non-condensing

Installation at altitudes above sea level:

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

Storage and Transport Conditions

The following table lists the storage and transport conditions for the TM5SDO4TAFS module:

Storage and Transport Conditions

Temperature

-40...+85 °C (-40...+121.0 °F)

Relative humidity

Digital Output Characteristics

The following table lists the digital output characteristics of the TM5SDO4TAFS module:

Digital Output

Number of output channels

4

Rated voltage

24 Vdc

Rated output current

2.0 A

Total current

5.0 A

Output protection

  • disable the channel in case of over-current or short circuit

  • inductive load resistance

Design

  • FET, 1x n switching, 1x p switching, type A

  • Output level can be read

  • Open-circuit detection

Switching voltage

24 Vdc (-15% / +20%);
I/O power supply minus residual voltage

Diagnostics status

Output monitoring with configurable delay

Leakage current when switched off

Residual voltage

< 480 mV at 2 A rated current without OSSD

Short circuit peak current

≤ 12 A

Test pulse length

Maximum 500 µs

Time between two test pulses

Minimum 49.5 ms

Re-arming after overload or short circuit detection

Set ReleaseOutput0x from 0 to 1. Then, after a positive edge on the SafeDigitalOutput0x channel, the output goes high.

Braking voltage when switching off inductive loads

maximum 90 Vdc

Due to the internal protective circuit, this braking voltage only takes effect starting at a load of typically 250 mA.

Maximum capacitive load

100 nF

Isolation voltage between channel and bus(1)

See note.

Open circuit detection

Via internal current measurement

  • output current <10 mA:

    Signal CurrentOK = FALSE

  • output current 10...50 mA:

    Signal CurrentOK = Undefined

  • output current >50 mA:

    Signal CurrentOK = TRUE

Error detection time

1 s
