What the line item actually is
The ABB 1SAP214200R0001 is the TU507-ETH interface terminal unit on the AC500 distributed automation I/O line — a backplane-facing termination block that carries Ethernet protocols into the rack through screw terminals, not a CPU or a communication module in its own right. Function is "For Ethernet protocols. Screw terminals". The same text appears in the title and description, so this order code maps the field-side Ethernet wiring onto the TU507 terminal carrier.
Electrical and cabinet envelope
Supply is 24 V DC from the backplane, which means it pulls no separate field power and slots straight into the standard AC500 power budget. Degree of protection is IP20, so the unit belongs inside a closed cabinet — no direct panel-door mount, no field-side exposure. Ambient air temperature for operation is 0... +60 °C; derating beyond that is not on the spec row, so anything hotter needs an enclosure strategy, not a software tweak.
Lifecycle and paperwork the desk will be asked for
RoHS compliance is recorded against EU Directive 2011/65/EU and Amendment 2015/863 dated July 22, 2019, and the REACH declaration carries a 2024-12-06 date, which is the freshest evidence a parallel-import desk typically asks for at goods-in. REACH disclosure is marked "True - contains substances > 0.1 mass percentage", so the SCIP entry fd57bbb7-ce16-4ef8-9dba-83720ed19276 is the document of record for the EU database and should travel with the shipment. WEEE classification is Category 5, small equipment with no external dimension over 50 cm, sold business-to-business — the take-back scheme on the invoice is B2B, not consumer.
How it sits against the TB521 coupler
The closest ABB AC500 neighbour by part class is the TB521 backplane coupler (1SAP112100R0270), which is a 2-slot communication module with Ethernet plus two serial interfaces RS232/RS485 — a different role on the same rack. The TU507-ETH is the terminal interface unit that lands wiring on the carrier; the TB521 is the coupler that hosts the communication modules themselves. They sit in series on the rack, not as alternatives, so cross-shopping the two order codes would not be a substitution move.
