This is a rugged Profibus DP
Repeater which enables connection of over 32 Profibus slaves thus
expanding and segmenting Profibus DP networks. The GRP housing is
shock and vibration tested and all electronics are encapsulated. The
housing is rated IP67.Bus cables should be terminated
at both ends with a Terminating Resistor to avoid signal reflection.
These Bus Terminating Resistors are specifically designed for Profibus
DP and both are 5 pole,
reverse-keyed, IP67, with male connectors.
