SpeedSys T11 - Description

Building upon the capabilities of the SpeedSys T10, the T11 is a single-channel speed monitor and switch with display. This display allows real-time speed values to be directly read, enhancing user convenience. Operators can quickly and easily view speed information without the need for additional equipment. This makes the SpeedSys T11 ideal for situations where fast and accurate visual feedback is essential for monitoring rotating machinery.

It features advanced signal conditioning, supporting both 3-wire and 2-wire voltage sensors. The system provides fast response times for overspeed and under-speed detection with configurable relay and analog outputs (4-20 mA). The T11 includes a Modbus TCP interface for seamless integration into automation networks and adds a TCP/IP communication port. With a measurement accuracy of 0.05%, a wide frequency range (0.025 Hz to 35 kHz), and robust housing, it is ideal for demanding industrial environments. The device operates on a 24 VDC power supply and offers comprehensive sensor monitoring functions, including open circuit and short circuit detection.
