Istec SpeedSys T20
The SpeedSys T20 is a dual-channel speed monitor and switch that delivers speed monitoring and protection functions to rotating equipment. It converts the signals from speed sensors to processed outputs. Its small technical footprint allows for a low-impact installation, to enable speed monitoring to a wide range of applications. The T20 is part of the SpeedSys tachometer series with the T10, T11 and T30.

Any speed function
The SpeedSys T20 provides overspeed, underspeed and acceleration protection, and has extensive monitoring functions, including dynamic sensor monitoring (comparing channels), reverse rotation, creep and standstill.
Standalone protection & monitoring
The system has redundant inputs for direct sensor connections and digital input signals, a redundant power supply, multi-channel integrated switching, and Modbus TCP & RTU communication.
Small technical and financial impact
The SpeedSys T20 is a DIN-rail module that provides a cost-effective solution for speed monitoring functions on rotating machinery.
Design
The SpeedSys T20 has four relays. The system accepts signal inputs from 3-wire voltage sensors (Hall-effect & proximity) and 2-wire voltage sensors (MPU).
Due to its compact design the T20 has a small technical footprint and features a low-impact installation. The T20 comes with easy to use push-in connectors and is mounted on a DIN-rail.
