Design and Performance
Reliable Physical Layer for PA/Fieldbus Networks
The FDC 157 provides the physical interface connecting PROFIBUS DP to PROFIBUS PA or FOUNDATION Fieldbus H1 segments, supplying bus power directly to field devices while maintaining signal integrity across the network.
High-Capacity Bus Power with Redundancy
An integrated bus supply delivering up to 1,000 mA supports a substantial number of connected field devices, while built-in redundancy capability helps maintain network availability in critical process applications.
Comprehensive Status Visibility
Dedicated LED indicators for DP and PA bus activity, bus faults, group errors, and supply voltage give operators immediate visual diagnostics without needing separate monitoring tools.
Robust Electrical Isolation
Full potential separation between the backplane bus, PROFIBUS DP, PROFIBUS PA, and the power supply — tested to 600 V DC — protects the control system from field-side electrical disturbances.
Extended Temperature Range Operation
Rated IP20 for a -25 °C to +60 °C operating range, the FDC 157 is built for reliable performance in demanding process automation environments beyond standard indoor conditions.
