Matching the module code alone is not enough when every channel may serve a different input, output or counter function.
Document the DI/DO assignment and fast-counter channels used by the existing program.
Confirm the S500 terminal unit, one-wire field terminals, auxiliary supply points and cabinet mounting.
Record DC523, 1SAP240500R0001 and the full nameplate.

The user program defines each of the 24 channels as a digital input or digital output, so the installed channel map must be preserved during replacement.
ABB specifies 24 V DC configurable DI/DO channels with a 0.5 A output rating per channel; verify the complete load and protection design.
Confirm the S500 terminal unit, one-wire field connections, process supply, channel allocation and any fast-counter use before ordering.
No automatic interchangeability should be assumed. DC523-XC is the extreme-condition version and the environmental approvals and installed assembly must be checked.
ABB lists 1SAP240500R0001 as Active and also lists the separate DC523-XC variant; the cited data sheet does not name a direct successor.
Send the nameplate, order code, terminal-unit model, DI/DO map, output loads, quantity, destination and required delivery date.
