ROTASLIP PU1TZAI/PU1TRHAI Underspeed Monitor
ATEX EN 60079/IECEx 60079

atex-iecex-appROTASLIP Underspeed Monitor EN 60079/IEC 60079 (Dust zone20/Gas zone0)
The Rotaslip PU1TZAI & PU1TRHAI underspeed monitors from SYNATEL are designed to detect a stud or bolt on a shaft and indicates a fault condition (open circuit) if the input speed reduces by 20% or more below set running speed. Available as a 2 wire, 24-240V ac/dc supply, FET output – PU1TZAI or a 5 wire, 15-240V dc/24-240V ac supply, relay output – PU1TRHAI underspeed sensor. Ideal for belt driven applications.
ATEX EN 60079 & IECEx  IEC 60079 dust & gas hazard area use approved. (Rotaslip PU1TZAI & PU1TRHAI underspeed Monitor).
