Profibus DP I/O Modules

Each 900PB Profibus DP I/O module provides a direct network interface for your I/O signals. Unlike “block I/O” devices that combine large, expensive processor blocks with snap-on I/O terminal blocks.  The 900 PB modules handle the network interface and I/O processing in one, compact multi-channel module. A space saving yet cost effective product for systems, that need to add a small quantity of I/O channels at existing control sites or network to new remote sites.

To ensure high performance, modules feature an advanced microcontroller techology. On-board address switches and automatic baud rate detection (up to12 Mbps) simplify installation. Four-way isolation prevents ground loops and increases noise immunity. Indicator LEDs and self-diagnostics help to quickly catch problems.
