Expand Discrete I/O Where the Machine Needs It

The 6ES7288-2DR16-0AA0 is the Siemens SIMATIC S7-200 SMART EM DR16 expansion module. It provides eight digital input channels and eight relay output channels, allowing additional discrete field signals to be integrated into an S7-200 SMART system.

Siemens specifies the digital inputs as 24 V DC inputs. The outputs are relay, dry-contact outputs, supporting 5–30 V DC or 5–250 V AC and up to 2 A at each output point.

With a compact 45 × 100 × 81 mm form factor, the EM DR16 is designed for space-conscious expansion within the S7-200 SMART platform.

Digital Inputs

Eight digital inputs are provided. Siemens specifies a rated input voltage of 24 V DC, with a maximum continuous voltage of 30 V DC.

Relay Outputs

Eight relay outputs use dry contacts. The specified voltage range is 5–30 V DC or 5–250 V AC, with up to 2 A per output point.

S7-200 SMART Discrete I/O Expansion

The EM DR16 is used as a digital I/O expansion module within the SIMATIC S7-200 SMART platform. Its eight inputs can accommodate 24 V DC field signals, while eight relay outputs provide dry-contact switching for connected loads.

This makes the module relevant where an S7-200 SMART installation needs additional discrete signal capacity without changing the basic compact architecture of the automation system.
