Description
Istec SpeedSys® T30 – 3-Channel Speed Monitor, Transmitter & Switch
Monitor rotating machinery with three independent speed channels, configurable relay outputs and Modbus TCP connectivity. The DIN-rail-mounted T30 supports standalone monitoring or additional monitoring functions alongside SpeedSys 200/300 systems.
Key functions
Overspeed, underspeed, acceleration, standstill, creep, reverse rotation and dynamic sensor monitoring. Suitable applications include turbines, compressors, expanders, marine machinery and industrial automation.
