Figure 2-18 DP/RS-232C Link for PROFIBUS-DP

The DP/RS-232C link consists of a compact 70 mm housing for standard rail mounting. Ideally the module should be installed vertically. The modules can be inserted one beside the other without gaps being necessary. The module is attached to PROFIBUS-DP via a 9-pin sub-D female connector. The RS-232C interface is implemented as a 9-pin sub-D connector.
