Use the exact Siemens order number and verify the system constraints before procurement.
Reserve eight consecutive input bits and eight consecutive output bits.
Plan the two DI groups and two relay DQ groups shown in Siemens wiring documentation.
Add 11 mA at 24 V DC for each relay coil that may be energized simultaneously.
Fuse loads and suppress inductive devices because the relay contacts are not overload protected.
Selected specialist-brand products requested for regional projects and available on Nordwel.
Auxiliary relay option for protection and control applications.

It provides eight 24 V DC digital inputs and eight relay digital outputs.
No. Half of its sixteen channels are inputs. For output-only selection, do not confuse DR16 with a sixteen-output relay module.
Each dry-contact output is rated 2 A, with an 8 A maximum for each common group.
Inputs are 24 V DC sink/source with IEC Type 1 sink characteristics and 4 mA nominal current.
Siemens lists 11 mA at 24 V DC per relay coil used, in addition to the input-channel and SM-bus load.
The eight inputs form two isolation groups and the eight relay outputs form two output groups.
Power consumption is 5.5 W and listed weight is 201.9 g.
An expandable SIMATIC S7-200 SMART CPU with sufficient SM-bus capacity is required. Compact CR and CRs CPUs are not compatible with EM expansion.
Software, licensing, controller, interface, shield and power-supply references.
Internal cable references for 40-channel input and output connections to field termination assemblies.
