Confirm on supplied product documentationDescription:
16-channel relay digital output moduleMatch the complete DO573 and article 1SAP231300R0000, then verify the S500-eCo digital I/O hardware generation, local or distributed S500-eCo I/O bus role, connection method and approved configuration. Physical similarity is not proof of compatibility.
Engineering note: After fitting DO573, clear unrelated faults, confirm local or distributed S500-eCo I/O bus or channel status, exercise the affected path and archive the acceptance evidence.
Installation planning
Confirm DO573 enclosure protection, cabinet heat dissipation, mounting arrangement and documented environmental limits before installation.
Storage and handling
Keep DO573 protected from moisture, contamination, impact and electrostatic discharge from receipt through installation.
Send the exact DO573 model, required quantity, destination and installed hardware details. Request current nameplate photographs and confirm compatibility before ordering.
Use DO573 where the engineered system calls for sixteen normally open relay output channels through local or distributed S500-eCo I/O bus; retain the stated 24 V DC or 120/240 V AC loads up to 2 A per channel and the specified screw- or spring-connector set conditions in the installation design.
Select this exact article when 16 normally open relay outputs rated to 2 A is required. Confirm the surrounding assembly, software record and field interface instead of choosing by module appearance.
Lifecycle assessment: Confirm current availability and lifecycle status against the latest manufacturer notice for the exact article number.
Ordering check: Verify the full model, article number, hardware revision and supported project release before purchasing.
Complete these six checks against the current project documentation and the official exact-model record.
Keep AC and DC relay duties separated in the channel schedule.
Record contact operation under the approved load conditions before release.
Use the full DO573 label and 1SAP231300R0000 to identify this 16-channel relay digital output module.
Its selection basis is 16 normally open relay outputs rated to 2 A, so contact technology must remain unchanged.
DO573 supplies sixteen normally open relay output channels, allowing the specified AC or DC contact duties.
Tie the specified connector arrangement to the relay-contact schedule so AC and DC duties remain correctly separated.
Review each DO573 contact for 24 V DC or 120/240 V AC service and a load no greater than 2 A per channel.
Retain relay-contact allocation, AC/DC duty, wiring reference and output status.
No. The replacement must preserve normally open relay contacts, article 1SAP231300R0000 and the documented load duty.
Separate AC and DC relay conductors as designed; also verify ventilation, orientation and ESD protection.
Witness every used relay contact changing state under the approved circuit arrangement.
Describe AC/DC contact duties, article 1SAP231300R0000, channel use, quantity and destination.
