What This Board Does in the Assembly
This ABB 1SAP187000R0001 is the TA5101-4DI option board — four 24 VDC digital inputs on a spring-cage terminal block. Each channel draws 5 mA, with a nominal delay between 4 and 8 ms. The IP20 enclosure keeps it inside a clean panel; no wet-area rating.
Mounting and Connection
Spring terminals included on the terminal block. Power and signal come from the backplane connector; no separate supply wiring needed. Input voltage range is 0 to 30 V DC.
