SpeedSys T20 - two channel tachometer

Istec SpeedSys T20 · 2-channel tachometer · 0.025 Hz to 35 kHz · speed monitor and switch · DIN-rail mount · speed signal to relay (4x), open collector (2x) and analog output (2x) · Modbus · accepts 2-wire and 3-wire voltage sensors

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 SpeedSys T20 has four relays. The system accepts signal inputs from 3-wire voltage sensors (Hall-effect & proximity), 2-wire voltage sensors (MPU), and digital input signals from speed encoders.

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.
