MBT 9600
Four Wire Modem for Teleprotection Applications
The MBT9600 is a dedicated four wire modem designed for use with Schweitzer Engineering Laboratories Inc. protective relays which use "Mirrored Bits" Relay-to-Relay logic communications. These relays use 9600 bps asynchronous communications as an integral part of mirrored bit logic communications for protection, monitoring and control.
Application specific features set the MBT9600 apart from conventional high speed modems. Conventional modems typically have retrain times in excess of 15 seconds and absolute data delays in excess of 25 milliseconds. These critical parameters make conventional modems unusable for most relaying applications.
Its compact size and ease of installation make it an ideal low cost alternative to conventional audio tone teleprotection systems. The circuitry is ideally suited for use over private networks such as conventional voice channels over analog microwave.
The MBT9600 is also suitable for application in other voice frequency systems which require environmentally hardened, dedicated four wire modems. The MBT9600 meets or exceeds all applicable ANSI/IEEE and IEC standards.
