Function is stated as for CS31 protocol with screw terminals, so the wiring side is a conventional rising-cage or screw clamp that a wireman can torque with a standard blade — no special tooling, no ferrules required on solid conductors. Supply voltage is 24 V DC, drawn from the same PSU feeding the rest of the slice; no independent feed is specified. ## Where it physically lives Degree of protection is IP20, so the TU551 is a cabinet-resident device — it sits inside a closed enclosure behind the panel door, not out in the field. Ambient air temperature for operation is 0…+60 °C, which is the standard cabinet interior envelope; derating kicks in only if the enclosure is unventilated and packed with heat-generating siblings, but the device itself does not impose a tighter window. For field-side mounts, conduit entries and a NEMA-rated cabinet carry the real IP work; the IP20 figure on the TU551 is the panel-internal rating and is the correct number to spec against for the indoor cabinet build. ## Production status and sourcing posture Lifecycle status for 1SAP210600R0001 is recorded as active, so the BOM line does not need a last-time-buy flag and a panel currently spec'd on this terminal unit can be re-ordered against ongoing production. ## What the buyer actually takes away For a procurement line already calling out the TU551-CS31 with screw terminals on a CS31 distributed-I/O build, the 1SAP210600R0001 is the order code that closes the BOM: active, RoHS/REACH-declared, 24 V DC, IP20, 0…+60 °C operation. Spec it in by that exact code where the wiring schedule calls for screw terminations; if the wiring schedule was originally drawn around the spring-terminal TU516, the 1SAP212000R0001 is the same-function equivalent but it is not a no-rewire swap.","metaTitle":"ABB 1SAP210600R0001 TU551 CS31 Interface, 24 V DC, IP20","metaDescription":"ABB 1SAP210600R0001 TU551-CS31 interface terminal unit, screw terminals, 24 V DC, IP20, operation 0…+60 °C.
