The Siemens 6ES7193-6TP00-0TP2 is a SIMATIC ET 200SP potential distributor module — specifically the PotDis-TB--B terminal block that distributes the bus potential to 16 process terminals on the connected I/O module. It carries 18 terminals total: 2 for the and bus feed, and 16 for the process terminals to the I/O module. The push-in terminals accept 0.14–2.5 mm² conductors (1.5 mm² with ferrule), so it handles standard control wiring without tools.
The and bus bars are rated 10 A max at 48 V, and the process terminals also carry 10 A max. That 10 A figure is the total current the distributor can pass to the module — it's not per-terminal. If the I/O module draws more than 10 A across its 16 terminals, you need to split the load or use a second distributor. The spec also calls for an external 10 A miniature circuit breaker with type B or C tripping characteristic on the supply lines, so the distributor itself is not a protection device — it's a pass-through bus bar in terminal form.
Physical fit and installation
At 15 mm wide, 74 mm tall, and 34 mm deep, this block takes up one standard ET 200SP slot width. It mounts onto the DIN rail as part of the I/O assembly — no separate DIN-rail footprint beyond the backplane bus. The push-in terminals face forward, so wiring access is straightforward even in a dense cabinet. Horizontal installation is rated -30 to 60 °C; vertical drops to 50 °C max. Above 2 000 m altitude, derate per the manual — the module is certified up to 5 000 m with restrictions.
