What the 6ES7193-6UP00-0DP2 does in an ET 200SP rack
The Siemens 6ES7193-6UP00-0DP2 is a potential distributor base unit for the ET 200SP distributed I/O system — it feeds the P1 and P2 bus potentials to downstream I/O modules without creating a new potential group. It carries 18 terminals: one connected to the P1 bus and 17 to the P2 bus, with the AUX rail also passed through from the left neighbor. That means a single module can distribute 24 VDC sensor supply or 48 V max to up to 17 adjacent I/O slices, keeping the field wiring common across the group.
Push-in terminals and 10 A bus capacity
Termination is push-in style, accepting 0.14 to 2.5 mm² conductors — solid or ferruled stranded wire pushes straight into the cage without a tool. Both the P1/P2 bus and the process terminals are rated 10 A max, so the module handles the combined load of a full I/O group without exceeding the bus current ceiling.
