Drop Connectors


StoneL offers a range of drop connectors for the various Fieldbus networks (Profibus PA,
Modbus, Foundation Fieldbus, AS-Interface, DeviceNet) with a protection circuit on each
drop, ensuring that a short circuit on a drop will not affect the rest of the bus. A trip of
240 mA for AS-Interface and 40mA for PROFIBUS PA and FF isolates the drop from the
rest of the network, and visibility indicates the short by means of LED.
