2MLL-PMEA Profibus-DP Master Module RS485 12 Mbps

2MLL-PMEA Profibus-DP Master Module

The 2MLL-PMEA is a Profibus-DP master module built for PNET interface racks. It carries one configuration port and one communication port. The physical layer is RS485, so standard Profibus cabling and connectors apply. Speed ranges from 9.6 kbps up to 12 Mbps. Segment distance reaches 1.2 km at low speed. The module addresses up to 126 nodes, with 32 nodes per segment. It ships as an open type unit, which suits panel builders and retrofit work.
