Use the exact Siemens order number and verify the system constraints before procurement.
Select QR16 when dry contacts or AC switching are required and high-speed pulses are not.
Assign loads so no group exceeds the documented 8 A maximum.
Compare switching rate and load type with the 100,000-cycle rated-load figure.
Reserve 150 mA at 24 V DC when all sixteen relays may be energized.
Selected specialist-brand products requested for regional projects and available on Nordwel.
Auxiliary relay option for protection and control applications.

Specialist brandAnswers below use Siemens official product documentation for this exact order number.
Siemens describes it as a sixteen-output relay module. It is output-only, unlike the mixed 8 DI/8 DQ EM DR16.
There are sixteen dry-contact digital outputs.
The official range is 5–30 V DC or 5–250 V AC.
Each point is rated 2 A and each common group is limited to 8 A.
Siemens lists 150 mA at 24 V DC when all relays are on, plus 110 mA from the SM bus.
No. Each field circuit needs correctly selected external protection.
The official system manual lists 100,000 open/close cycles at rated load.
The module measures 45 × 100 × 81 mm, weighs 221 g and consumes 4.5 W.
Software, licensing, controller, interface, shield and power-supply references.
Internal cable references for 40-channel input and output connections to field termination assemblies.
