The DVPPF02-SL is a PROFIBUS DP Slave Communication Module for Delta PLCs, handling fieldbus connectivity via a DB9 connector and high-speed RS-485 transmission. It requires shielded twisted pair cable for the bus line and provides 500VDC electrical isolation between the module and the network, which helps protect the PLC backplane from ground loops and transient spikes on the fieldbus. Rated for operation from 0°C to 55°C with 50% to 95% humidity and pollution degree 2 — typical for a control cabinet environment without aggressive atmospherics.
Integration note
The DB9 connector and RS-485 physical layer mean this module drops into a standard PROFIBUS DP segment without special adapters. The 500VDC isolation is worth noting if the panel shares a backplane with non-isolated devices — it adds a barrier that a bare transceiver does not.
