          PRODUCT DESCRIPTION

          SPTU 240 R2 Power-Supply and Output-Relay Module

          ABB SPTU 240 R2 combines an auxiliary power supply with output relays for compatible SPACOM protection assemblies. Its isolated converter accepts AC or DC auxiliary power and generates internal voltage rails, while the R2 version provides a normally open trip contact.

          The withdrawable module includes relay-drive circuits and an interface for external control signals. Stabilized amplifier and relay-coil supplies are separate from the unstabilized logic rail; the measuring module generates its own 5 V supply. Contact loading depends on the output group and switching duty.

          SYSTEM & REPLACEMENT CHECK

          Information needed before ordering

          SYSTEM INTEGRATION

          Integrate SPTU 240 R2 in the documented SPACOM arrangement

          SPTU 240 R2 combines the power converter, output relays, relay-drive circuits and external-control input electronics. In the SPAM 150 C assembly it is the withdrawable module behind the front panel. It supplies the measuring module but does not itself provide all of that module's protection functions. The motor-current measuring inputs and their frequency ratings must not be presented as SPTU auxiliary-supply specifications.
          The converter accepts 80...265 VAC/DC and separates its primary and secondary circuits galvanically. Its stabilized rails are +24 VDC for relay coils and +12/-12 VDC for amplifiers; the +8 VDC logic feed is unstabilized. The measuring module generates the final +5 V logic rail and supervises the electronics supply. The primary F1 fuse is rated 1 A, slow.
          The SPAM 150 C connection reference assigns the normally open trip/restart contacts to 65-66 and 74-75, while signalling uses 70-71-72, 68-69, 77-78 and 80-81. These groups have different short-time and DC-breaking limits. The 30 A value applies only to a 0.5-second make-and-carry duty, not continuous loading. Use the correct host-relay diagram; the terminal numbers are not a universal pinout for every SPACOM assembly.

          Features:

          • Isolated converter with three distinct supply functions
          • Separate trip/restart and signalling contact duties
          • Host-specific external-control and terminal mapping
          The 80...265 VAC/DC auxiliary circuit can carry hazardous voltage. Work must follow the applicable ABB isolation and electrical-safety procedure; contact ratings and terminal assignments require the correct host-relay reference.
          INTERCHANGEABILITY

          Verify SPTU 240 R2 before replacement

          Match the complete SPTU 240 R2 designation before selecting a replacement. The 240 version accepts 80...265 VAC/DC, whereas the SPTU 48 R2 version is intended for 18...80 VDC. R2 has a normally open trip contact; R3 has a normally closed contact. Similar appearance and a matching case do not make those variants interchangeable.
          The ABB SPAM 150 C manual lists SPTU 240 R2 under ordering number RS 941 021-AA; the SPAJ 160 C manual lists RS 911 021-AA. These are different source contexts, not an authorized equivalence statement. Compare the host relay, its applicable parts list and the offered module marking before a distributor substitutes one ordering reference for another.
          Inspect the connector and contact condition, mechanical damage, contamination and corrosion under the responsible maintenance procedure. ABB warns that the electronics are sensitive to electrostatic discharge and that the modules require protection from moisture and mechanical stress. After replacement, qualified personnel should verify the appropriate supply, supervision and output-contact functions before return to use; a lit auxiliary-power indicator alone is not a complete acceptance test.

          Features:

          • R2 contact form and 240-series input-range match
          • Host-specific ordering number and module identity
          • ESD-aware inspection and functional acceptance
          Do not replace an R2 normally open trip arrangement with R3 or assume that all SPTU 240 R2 ordering references are interchangeable. Verify the host-relay parts list and the intended trip-contact behavior first.

          FREQUENTLY ASKED QUESTIONS

          Questions buyers ask about SPTU 240 R2

          Direct answers about identity, compatibility, stock, warranty, payment and shipping.

          • Can SPTU 240 R3 replace an R2 module without changing the trip circuit?

            Not as an assumed direct replacement. ABB identifies R2 with a normally open trip contact and R3 with a normally closed trip contact. The contact-duty limits also differ. Match the intended trip behavior and the exact host-relay variant before any substitution.

          • Does SPTU 240 R2 support a 48 VDC auxiliary supply?

            The specified auxiliary range for the 240 R2 is 80...265 VAC/DC, so 48 VDC is outside that range. ABB separately identifies SPTU 48 R2 for 18...80 VDC. The number 240 is a variant designation, not a 240 W output-power rating.

          • Where is the 5 V logic supply generated?

            SPTU provides an unstabilized +8 VDC feed. The measuring relay module contains the stabilizer that produces its required +5 V logic supply. The SPTU amplifier rails at +12/-12 V and its +24 V relay-coil rail are stabilized separately; these are different internal supply functions.

          • How should the 30 A output-contact figure be interpreted?

            For the SPAM 150 C normally open trip/restart contacts, 30 A is the make-and-carry limit for 0.5 seconds. The continuous rating is 5 A, and the three-second make-and-carry limit is 15 A. DC breaking capacity has its own voltage and circuit-time-constant conditions; 30 A is not a continuous or interrupting rating.

          • Which fuse protects the primary side of the module?

            ABB identifies F1 on the module PCB as a 1 A slow fuse. That is a fuse specification, not the module's continuous input-current rating. Follow the applicable manufacturer maintenance and isolation procedure; the fuse value does not provide a safe energized troubleshooting method.

          • Are the 4 W and 6 W figures available output power?

            No. The SPAM 150 C technical table gives approximately 4 W under quiescent conditions and 6 W under operating conditions as consumption figures. They are not usable DC output-power ratings and do not establish the current available from each internal supply rail.

          • Is this a complete SPAM 150 C motor protection relay?

            No. SPTU 240 R2 is the power-supply and output-relay module. ABB lists the SPCJ 4D34 measuring/protection module, the relay case and other assemblies separately. A distributor quotation for SPTU alone should not imply that those additional assemblies or a complete protection relay are included.

          • Why do the ABB manuals show different SPTU 240 R2 ordering numbers?

            The SPAM 150 C reference lists RS 941 021-AA, while the SPAJ 160 C reference lists RS 911 021-AA. This evidence establishes two manual-specific listings but does not explain or authorize interchangeability. Resolve the required ordering reference against the customer's host relay and applicable parts list before confirming a substitute.
