Siemens 6ES7288-2DR16-0AA0 SIMATIC S7-200 SMART EM DR16 Relay I/O Module

6ES7288-2DR16-0AA0 combines 8 digital inputs at 24 V DC with 8 dry-contact relay outputs, making it suitable when one expansion position must add both sensing and switching points.

6ES7288-2DR16-0AA0 relay contacts are specified for external circuits in the range of 5–30 V DC or 5–250 V AC. Each field load needs its own correctly protected supply and must remain within the contact rating.

6ES7288-2DR16-0AA0 supports up to 2 A per relay point, while the total through one common group must not exceed 8 A. Inductive loads should use appropriate suppression.

6ES7288-2DR16-0AA0 provides eight 24 V DC sink/source inputs, each drawing about 4 mA when active, for proximity sensors, limit switches and dry contacts.

6ES7288-2DR16-0AA0 measures 45 × 100 × 81 mm, weighs about 202 g, consumes approximately 5.5 W and draws 145 mA from the SM bus.

6ES7288-2DR16-0AA0 can switch many contactor coils and solenoid circuits when their voltage, steady current and inrush stay within the relay ratings. Confirm the real load data and add a flyback diode, RC network or other suppression when required.

For 6ES7288-2DR16-0AA0, provide the CPU order number, input sensor type, every load voltage, running and inrush current, AC or DC duty, common-group plan, quantity and destination.
