Features:

  • Four Programmable Relay Contact Outputs
  • Four Additional 24 V DC Digital Outputs
  • Configurable Relay Transient Suppression
The ABB SAFT175RDO provides four programmable independent relay contact outputs for compatible SAMI STAR drives. The contacts can be selected as normally open or normally closed and are rated up to 250 V AC, 5 A continuous and 10 A inrush, making the card suitable for potential-free external control and status interfaces.

In addition to its relay contacts, the ABB SAFT175RDO provides four 24 V DC digital outputs. This combination gives compatible SAMI STAR systems both relay-based potential-free signaling and conventional digital output capability within the same dedicated output card.

The ABB SAFT175RDO includes S5–S8 switch settings for relay-output transient suppression. This feature allows the output configuration to be matched more appropriately to connected loads, while the final switch settings and wiring should follow the applicable SAMI STAR installation documentation.

The SAFT175RDO ABB Relay Output Card may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

  • Legacy SAMI STAR Drive Maintenance: The ABB SAFT175RDO is primarily valuable for maintaining existing ABB/Strömberg SAMI STAR drive installations. It provides a practical replacement option when an original relay-output function needs to be restored without immediately redesigning the complete drive control architecture.
  • Potential-Free External Control Signals: The ABB SAFT175RDO is suited to applications requiring relay-based potential-free contacts from the SAMI STAR digital output system. These outputs can interface with external control circuits, status circuits and compatible field devices within their specified electrical limits.
  • Drive Status and Interlock Interfaces: The ABB SAFT175RDO can be used where relay outputs are required to interface drive-related commands, permissives, interlocks or status indications with external control equipment. The actual signal assignment depends on the SAMI STAR application software and system wiring.
  • Legacy Plant Reliability and Spare-Part Support: The ABB SAFT175RDO supports long-life industrial installations in which replacing one output card is preferable to redesigning an entire control system. Maintaining an appropriate spare inventory can help reduce troubleshooting and recovery time for aging SAMI STAR equipment.
  • Relay-Based Status and Command Signaling: The ABB SAFT175RDO converts compatible SAMI STAR digital-output functions into relay contact states that can be used by external control circuits. NO/NC selection provides flexibility when designing or maintaining existing signal logic.
  • Four-channel relay-output interface: The ABB SAFT175RDO combines four relay contact outputs with four additional 24 V DC digital outputs. This allows different types of external signal interfaces to be handled through the same dedicated SAMI STAR output-card architecture.
  • Centralized Drive-Level Diagnostics: The ABB SAFT175RDO itself is an output interface rather than a standalone diagnostic controller. Engineers should therefore evaluate output behavior together with SAMI STAR control-panel indications, drive fault information, parameter settings and electrical measurements during troubleshooting.
  • Transient-Suppression Configuration: The ABB SAFT175RDO provides S5–S8 switch settings associated with relay transient suppression. Correct configuration can be important when the relay outputs operate external loads with significant switching transients, and settings should follow the applicable ABB wiring and application documentation.
  • Defined Relay Switching Capacity: The ABB SAFT175RDO provides a clearly defined relay interface with contacts rated for 250 V AC, 5 A continuous and 10 A inrush. This gives maintenance engineers a concrete electrical limit for evaluating compatible external circuits rather than relying on generic relay-output assumptions.
  • Output Architecture: four potential-free relay-contact output channels controlled by the SAMI STAR digital-output system. his four-channel relay-output architecture provides potential-free interfaces for external control and status circuits.
  • Practical Legacy Replacement: The ABB SAFT175RDO can reduce the scope of maintenance work when the existing SAMI STAR drive remains serviceable and only the relay-output function requires replacement. Using a matching card can avoid unnecessary rewiring or changes to the established drive control architecture.
  • Application-Dependent Reliability: The ABB SAFT175RDO is designed for industrial drive interface duties, but actual service life depends on contact loading, switching frequency, environmental conditions, wiring quality and maintenance practices. Staying within the specified relay ratings and using the appropriate transient-suppression configuration is important for reliable long-term operation.
Description
The ABB SAFT175RDO is a dedicated relay output card used within the ABB/Strömberg SAMI STAR adjustable frequency drive architecture. It provides four programmable independent relay contact outputs, with contacts selectable as normally open (NO) or normally closed (NC), making it suitable for interfacing the drive with external control circuits and field devices.

The ABB SAFT175RDO converts four SAMI STAR digital output channels into four potential-free relay-contact output channels. The relay contacts are rated at up to 250 V AC, 5 A continuous and 10 A inrush, providing a practical interface for potential-free control and status signals in compatible legacy drive installations.

The ABB SAFT175RDO incorporates S5–S8 switch settings associated with transient suppression for the relay outputs. This provides installation flexibility when the card is connected to external loads that may generate switching transients, while the actual suppression configuration should follow the applicable SAMI STAR wiring and application documentation.

The ABB SAFT175RDO is particularly relevant to maintenance teams supporting long-service SAMI STAR equipment. As a dedicated hardware output card rather than a modern networked I/O module, it allows compatible legacy drive systems to retain their existing control architecture without requiring an immediate complete drive replacement.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What firmware or software dependencies does the ABB SAFT175RDO have?
The ABB SAFT175RDO is a dedicated hardware output card rather than an independently programmable controller. It does not provide its own Ethernet, fieldbus or user-facing firmware environment; output behavior is determined by the compatible SAMI STAR drive control architecture and its application configuration.
Does the ABB SAFT175RDO support Ethernet, PROFIBUS, Modbus or other fieldbus protocols directly?
The ABB SAFT175RDO does not provide an independent fieldbus communication interface. Its primary function is relay and digital output signaling within the SAMI STAR control architecture; network communication, where present, belongs to the host drive and its associated communication/interface equipment.
How should the ABB SAFT175RDO relay outputs be wired?
The ABB SAFT175RDO relay contacts are selectable as NO or NC and should be wired according to the applicable SAMI STAR connection diagram. The external circuit must remain within the documented 250 V AC, 5 A continuous and 10 A inrush contact limits.
Does the ABB SAFT175RDO provide galvanically isolated relay contacts?
The ABB SAFT175RDO uses relay contacts to provide potential-free output signaling. This allows the relay contact circuit to be used as an interface to external circuits, but the complete isolation and safety characteristics must be evaluated according to the actual drive wiring and application.
How deep are the diagnostics provided by the ABB SAFT175RDO?
The ABB SAFT175RDO is primarily an output interface rather than a standalone diagnostic module. Troubleshooting should therefore combine relay/output measurements with the diagnostic functions of the associated SAMI STAR drive and its control panel or service documentation.
