9300 9852 9852 Fieldbus Redundant Link Module

9300 9852 The 9852 is a Profibus DP protocol fieldbus redundant link module that converts a single bus (port M) and a dual redundant bus (ports A and B) to each other, either a single cable bus to a redundant Profibus DP bus or a redundant Profibus DP bus to a single cable bus.

9300 9852 9852 Data received from port M is broadcast to ports A and B, but data from ports A or B are forwarded to port M on a first-come, first-served basis, so that only one working path is established at the same time. The device monitors the communication status in real time, and switches to the redundant port when the receiver of the working port detects a bus fault, and vice versa. The device supports dip switches to set fixed or adaptive rates and supports the 10 common rates of the Profibus DP bus.

9300 9852 The 9852 can be placed directly after a Profibus DP master to convert a single-cable bus to a redundant bus, or in a slave to convert a redundant bus to a non-redundant cable, with optical isolation and interference reduction. The product is industrial grade design, IP30 protection level, wave pattern aluminium reinforced chassis, 35mm rail mounting, DC (12~36V) wide power input, with relay alarm output, dual power supply redundancy protection and other advantages.
