The RM-1 Redundancy Manager is designed for Ethernet redundant ring systems utilizing the company's rail hubs and switches
The RM-1 Redundancy Manager is designed for Ethernet redundant ring systems utilizing the company's rail hubs and switches. The manager automatically supervises the ring structure, and is responsible for detection and bypass of network faults within 300 ms of their occurrence. The unit provides eight twisted-pair ports on 10BASE-T with shielded RJ45 connectors to connect operator stations, PLCs, I/O blocks, or other twisted-pair inputs, plus two free slots for 100 Mbit modules or fiber optic links. If 100 Mbit modules are utilized, the user may select between 100BASE-TX or 100BASE-FX.
The RM-1 is built on a fully front-accessible 19-in. chassis, suitable for control rooms or standard rack-mounts. It operates on 24 V DC supplied over the rail terminal block, and which may also be configured for redundancy. It is also designed to function in harsh industrial environments.
