Moore Industries SFY Functional Safety Frequency-to-DC transmitter

May 7, 2017 – Moore Industries has released the SIL 3 capable SFY Functional Safety Frequency-to-DC Transmitter with display.

Part of the FS Functional Safety Series, the SFY boasts “reliable and accurate” monitoring of frequency or pulse signals in Safety Instrumented Systems (SIS) that help provide over speed protection by sending signals that warn the logic solver to alarm or shut down the monitored device for plant, process and personnel safety. The SFY converts the input signal to a proportional input-to-output isolated 4-20mA output ready for direct interface with a Safety System, readout instrument, recorder, PLC, DCS, or SCADA system. It is designed and approved for use in a variety of processes and factory automation SIS including turbine flow meters, magnetic pickups, dry contact closures, variable frequency drives, turbine tachometer generators, rotating equipment, motor and conveyor speed as well as pulse and frequency output transducers. Moore says the SFY has been certified by exida to ensure conformance with IEC 61508:2010 standards for safety-related applications.
