The Siemens 6ES7193-6TP00-0TP1 is a potential distributor terminal block for the ET 200SP distributed I/O system, designated PotDis-TB--R. It distributes 18x bus potential to the connected I/O modules via push-in terminals, carrying up to 10 A on the and bus.
What the ratings mean for fit
The 15 mm width and 34 mm depth match the standard ET 200SP form factor — it occupies one slot on the mounting rail and mates directly to the backplane bus without additional wiring for the potential group. The 10 A rating on the and bus is the current budget for the downstream modules in that potential group. Exceed 10 A total draw and the bus bar or the external 10 A circuit breaker (type B or C) upstream will trip. Sixteen process terminals connect to the I/O module's field wiring; the block itself carries no add-on terminals. The push-in terminals accept 0.14–2.5 mm² solid or 0.2–1.5 mm² ferruled stranded — standard for ET 200SP field wiring. Horizontal installation range is -30 °C to 60 °C; vertical derates the max to 50 °C. The -30 °C floor is the same in both orientations.
