1.3.2 Low-Side Power Switches
The PB-DOUT8 module is provided with four two-channel Siemens TLE 5224 G2 smart
power transistors for low-side switching having the following features:
• overload protection
• power limitation
• short-circuit protection
• overtemperature monitoring
• overvoltage protection
• ESD protection
1.3.3 Board Interfaces
The PB-DOUT8 piggyback module is provided with two digital I/O connectors. The one
on the input side is a 15-pin double-row connector, the one on the process side a 12-pin
double-row connector. The input connector is wired via the carrier board to a 50-pin
DSUB or to a 50-pin FB connector, while the process interface is wired to the carrier
board’s VMEbus socket.
