The DS200SDCCG1AGD DS215SDCCG1AZZ01B is a Profibus DP protocol-based fieldbus redundant link module that interchanges a single bus (port M) with a dual redundant bus (ports A and B), converting either a single-cable bus to a redundant Profibus DP bus or a redundant Profibus DP bus to a single-cable bus. Profibus DP bus to a single cable bus.

DS200SDCCG1AGD DS215SDCCG1AZZ01B Data received from the M port is broadcast to the A and B ports, but data from the A or B ports are forwarded to the M port 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 over to the redundant port when the receiver of the working port detects a bus fault, and vice versa. When the receiver of the working port detects a bus failure, it switches to the redundant port 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.

The DS200SDCCG1AGD DS215SDCCG1AZZ01B can be placed directly after the 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.
