The TM5SPS10FS Safety Power Distribution module (SPDM), in association with its dedicated, left-isolating TM5ACBM4FS Safety bus base, is a power source for specified non-safety-related I/O modules. The Safety Power Distribution module supports the pre-defined safe state of power-off (de-energized) to the I/O modules connected. As illustrated below, the TM5SPS10FS Safety Power Distribution module is used to create an isolated group of non-safety related I/O modules.

(2) Safety I/O modules

(4) Non-safety-related I/O modules

(6) 24 Vdc I/O power segment of safety-related I/O modules
(7) 24 Vdc I/O power segment of non-safety-related I/O modules

SDPM Safety Power Distribution module: TM5SPS10FS
In the case of a safety-related request by the Safety Logic Controller, the Safety Power Distribution module disables the 24 Vdc I/O power segment bus. Consequently, power to the connected sensors and actuators of those I/O modules using the bus within the segment is removed. Likewise, the 24 Vdc safety-related output of the Safety Power Distribution module is disabled.
In an appropriate hardware configuration, the 24 Vdc safety-related output of the Safety Power Distribution module can be used to remove power from an external power supply directly, removing residual connection to power. For example, output voltage and current may need to be removed from, in addition to those connected to the internal 24 Vdc I/O power segment bus, external relays, contactors, drive inputs or other forms of actuators.
Principally, however, the 24 Vdc safety-related output of the Safety Power Distribution module (SDPM) is used to supply a non-safety-related Power Distribution Module (PDM), as illustrated in the following graphic:
(PS1) External isolated power supply 24 Vdc
(PS2) External isolated power supply 24 Vdc
(PS3) External isolated power supply 24 Vdc
An SPDM can only de-energize a maximum of 10 A output current of connected non-safety-related I/O modules.

|
UNINTENDED EQUIPMENT OPERATION |
|
oIf you need to de-energize more than 10 A, add more SPDM modules. oMake sure that direct voltage is only and exclusively supplied by the SPDM to any non-safety-related I/O module that is to be de-energized. oMake sure that the segment on the right side of the SPDM does not contain any bus base and module combination that can provide external power to the 24 Vdc I/O power segment bus to the left (to the SPDM). |
|
Failure to follow these instructions can result in death, serious injury, or equipment damage. |
|
|
|
UNINTENDED EQUIPMENT OPERATION |
|
oOnly connect the non-safety-related I/O modules specified as compatible by the present documentation to the Safety Power Distribution module. oIf using an external source of power to supply sensors and/or actuators of the connected I/O modules, use the 24 Vdc output of the Safety Power Distribution module to control the removal of power provided by the external source. oOnly use one Safety Power Distribution module for the potential group of non-safety-related I/O modules. |

Failure to follow these instructions can result in death, serious injury, or equipment damage. |

(1) Some modules use the 24 V I/O Power Segment as a source of power for communications on the TM5 bus. When the Safety Power Distribution module removes power from the 24 V I/O Power Segment, these modules cease communication with the Sercos III Bus Interface, which then will produce configuration exceptions. For example, when the Safety Power Distribution module removes power, these modules cannot be found during a Sercos SCAN procedure. NOTE: All compatible TM5 Electronic Modules must be of a revision PV: 01 / RL: 02 or greater. |

oDo not associate components of a slice that have different colors. oVerify that correct terminal blocks (minimally, matching colors and correct number of terminals) are installed on the appropriate electronic modules. |

Failure to follow these instructions will result in death or serious injury. |
Part of the defined safe state is to achieve the operational definition of the removal of power. After the removal of power to an external power supply, power must remain removed for a period of at least 250 ms, and up to 1 s to prevent the restart of an actuator. This time is required to discharge any internal energy storage to affect the shut-down of the actuators.
The safety-related function initiating the removal of power must fulfill the requirements of the intended overall safety level (Category, PL, etc.) as determined by your risk assessment. The concept of the TM5SPS10FS Safety Power Distribution module can, with an appropriate architecture, achieve a safety objective up to Category 4 / PL e according to EN ISO 13849-1.
