Features:
- Establishes a 24 V DC control-potential group for ET 200S motor starters.
- Plugs onto a matched PM-D terminal module while field wiring stays on the base.
- Operates in vertical or horizontal stations within the documented environmental limits.
The module converts a correctly wired 24 V DC infeed into the control-potential distribution used by the starter group.
Its removable electronics and fixed terminal base divide serviceable functions from permanent conductors.
Supply range, surge immunity and mechanical environment determine whether the PM-D can maintain the control group.
The Siemens 3RK1903-0BA00 ET 200S PM-D 24 V DC Power Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Feeding the motor-starter control group
- Input range: The PM-D accepts 24 V DC only within the documented 20.4 to 28.8 V window.
- Group source: Its output establishes control potential for the downstream starter positions.
- Shared effect: A lost PM-D supply can affect multiple starters even when their individual commands are valid.
- Trace order: Diagnosis begins at the infeed, continues through the terminal base and then checks the PM-D state.
Separating electronics from permanent terminations
- Terminal base: The fixed PM-D terminal module holds the supply conductors.
- Module seating: The power module plugs into the base contacts and locks into the station.
- Exchange boundary: The electronics can be removed without releasing every field conductor.
- Match requirement: Base and PM-D order-number family must agree before insertion.
Relating orientation to temperature and enclosure conditions
- Two orientations: Vertical and horizontal mounting are both documented.
- Thermal limit: The complete station must remain within the 0 to 60 °C operating range.
- Altitude limit: Installation is restricted to the documented maximum of 2000 m.
- Protection scope: IP20 applies to the correctly assembled module and does not replace cabinet protection.
Protecting the control group from mechanical and electrical stress
- Shock: The assembly is rated for the documented 5 g, 11 ms shock condition.
- Vibration: Continuous mechanical exposure remains within the published 2 g limit.
- Surge path: Different surge values apply conductor-to-earth and conductor-to-conductor.
- EMC setting: Industrial Class A operation requires the surrounding wiring and enclosure practices to preserve EMC behavior.
