SpeedSys® T10 to replace Jaquet T401 SpeedSys® is a tachometer (Speed transmitter, monitor & switch) The SpeedSys T10 is a single-channel speed monitor and switch that delivers speed-monitoring 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 T10 is part of the SpeedSys tachometer series with the Speedsys T20 and the SpeedSys T30. Functions: Speed, overspeed, underspeedInputs accepted: Hall effect sensor, electromagnetic sensorOutputs: 1x 4-20 mA analog output, 1x open collector frequency output Relay: 1x DPST relay, 1x SPST relayInterface: Modbus TCPHumidity protection: Conformal coatingHousing: DIN rail with push-in connectorsCertifications: CE, UKCA, DNV The SpeedSys T10 is used as a monitoring and switching device for speed conditions on rotating machinery. Typical applications of T10 are: Aeroderivatives Micro turbines Wind turbines Gas- and steam turbines Hydro turbines (Kaplan, Francis, Pelton) Compressors Expanders Marine applications Elevators General automation If you were looking after Jaquet (TE) T401 has been made obsolete = discontinued. You can extend the life of the current installations simply swapping a T10 on place! The SpeedSys T10 is a functional replacement for the T401 series. Jaquet T401 replacement by SpeedSys T10 by IstecThe SpeedSys T10 is developed to replace the Jaquet transmitter series declared obsolete by manufacturer TE connectivity (Jaquet). SpeedSys T10 can be used to replace the following Jaquet parts: T401 series, T402 series, FTW113 DC 24I, FTW113 DC 24U, FTW123 DC 24, FTV 1398 Line driver. SpeedSys T10 and consult the datasheet for all deviations and to assess suitability for your application. If you have any questions about the conversion, please consult your Istec representative. Disclaimer The SpeedSys T10 has additional features, but some functionalities deviate from the Jaquet T401. Additional features: Remote reset TCP Modbus Marine class certification Dual relay output Deviations Not suitable for 2-wire Hall sensors Not suitable for Namur sensors No voltage (0-10 V) output option Key advantages of the new SpeedSys T10 tachometer products: Easy replacement: Our new tachometers are designed to be a direct replacement for the Jaquet T-series. Minimal modifications are required during installation, saving time and resources. Enhanced functionality: Our new tachometer line features several improvements to boost operational efficiency, including enhanced relay features and Modbus TCP.
